1. INTRODUCTION
1.1. The assignment
This report is part of the set of reports describing the results of the long-term measurements This
report is part of the set of reports describing the results of the long-term measurements conducted
in Deurganckdok aiming at the monitoring and analysis of silt accretion. This measurement
campaign is an extension of the study “Extension of the study about density currents in the
Beneden Zeeschelde” as part of the Long Term Vision for the Scheldt estuary. It is complementary
to the study ‘Field measurements high-concentration benthic suspensions (HCBS 2)’.
The terms of reference for this study were prepared by the ‘Departement Mobiliteit en Openbare
Werken van de Vlaamse Overheid, Afdeling Waterbouwkundig Laboratorium’ (16EB/05/04). The
repetition of this study was awarded to International Marine and Dredging Consultants NV in
association with WL|Delft Hydraulics and Gems International on 10/01/2006. The project term was
prolonged with an extra year from April 2007 till March 2008.
Waterbouwkundig Laboratorium– Cel Hydrometrie Schelde provided data on discharge, tide,
salinity and turbidity along the river Scheldt and provided survey vessels for the long term and
through tide measurements. Afdeling Maritieme Toegang provided maintenance dredging data.
Agentschap voor Maritieme Dienstverlening en Kust – Afdeling Kust and Port of Antwerp provided
depth sounding measurements.
The execution of the study involves a twofold assignment:
 Part 1: Setting up a sediment balance of Deurganckdok covering a period of one year, i.e.
04/2007 – 03/2008
 Part 2: An analysis of the parameters contributing to siltation in Deurganckdok
1.2. Purpose of the study
The Lower Sea Scheldt (Beneden Zeeschelde) is the stretch of the Scheldt estuary between the
Belgium-Dutch border and Rupelmonde, where the entrance channels to the Antwerp sea locks
are located. The navigation channel has a sandy bed, whereas the shallower areas (intertidal
areas, mud flats, salt marshes) consist of sandy clay or even pure mud sometimes. This part of the
Scheldt is characterized by large horizontal salinity gradients and the presence of a turbidity
maximum with depth-averaged concentrations ranging from 50 to 500 mg/l at grain sizes of 60 100 m. The salinity gradients generate significant density currents between the river and the
entrance channels to the locks, causing large siltation rates. It is to be expected that in the near
future also the Deurganckdok will suffer from such large siltation rates, which may double the
amount of dredging material to be dumped in the Lower Sea Scheldt.
Results from the study may be interpreted by comparison with results from the HCBS and HCBS2
studies covering the whole Lower Sea Scheldt. These studies included through-tide measurement
campaigns in the vicinity of Deurganckdok and long term measurements of turbidity and salinity in
and near Deurganckdok.
The first part of the study focuses on obtaining a sediment balance of Deurganckdok. Aside from
natural sedimentation, the sediment balance is influenced by the maintenance and capital dredging
works. This involves sediment influx from capital dredging works in the Deurganckdok, and internal
relocation and removal of sediment by maintenance dredging works. To compute a sediment
balance an inventory of bathymetric data (depth soundings), density measurements of the

deposited material and detailed information of capital and maintenance dredging works will be
made up.
The second part of the study is to gain insight in the mechanisms causing siltation in
Deurganckdok, it is important to follow the evolution of the parameters involved, and this on a long
and short term basis (long term & through-tide measurements). Previous research has shown the
importance of water exchange at the entrance of Deurganckdok is essential for understanding
sediment transport between the dock and the river Scheldt.
1.3. Overview of the study
1.3.1. Reports
Reports of the project ‘Opvolging aanslibbing Deurganckdok’ between April 2007 till March 2008
are summarized in Table 1-1. An overview of the HCBS2 and ‘Opvolging aanslibbing
Deurganckdok’ (between April 2006 till March 2007) reports are given in APPENDIX K.
This report 2.14, is one of a set of reports that gains insight in sediment and water transport
between Deurganckdok and the river Scheldt, which belongs to the second part of this project.

2. THE MEASUREMENT CAMPAIGN
2.1. Overview of the parameters
The first part of the study aims at determining a sediment balance of Deurganckdok and the net
influx of sediment. The sediment balance comprises a number of sediment transport modes:
deposition, influx from capital dredging works, internal replacement and removal of sediments due
to maintenance dredging (Figure 2-1).
Figure 2-1: Elements of the sediment balance
A net deposition can be calculated from a comparison with a chosen initial condition t0 (Figure 2-2).
The mass of deposited sediment is determined from the integration of bed density profiles
recorded at grid points covering the dock. Subtracting bed sediment mass at t0 leads to the change
in mass of sediments present in the dock (mass growth). Adding cumulated dry matter mass of
dredged material removed since t0 and subtracting any sediment influx due to capital dredging
works leads to the total cumulated mass entered from the Scheldt river since t0.

The main purpose of the second part of the study is to gain insight in the mechanisms causing
siltation in Deurganckdok. The following mechanisms will be aimed at in this part of the study:




Tidal prism, i.e. the extra volume in a water body due to high tide
Vortex patterns due to passing tidal current
Density currents due to salt gradient between the Scheldt river and the dock
Density currents due to highly concentrated benthic suspensions

Figure 2-3: Transport mechanisms
These aspects of hydrodynamics and sediment transport have been landmark in determining the
parameters to be measured during the project. Measurements will be focussed on three types of
timescales: one tidal cycle, one neap-spring cycle and seasonal variation within one year.
Following data are being collected to understand these mechanisms:
 Monitoring the freshwater input (discharge) from the tributaries into the river Scheldt.
 Monitoring salinity and sediment concentration in the Lower Sea Scheldt at permanent
measurement locations at Oosterweel, up- and downstream of the Deurganckdok.
 Long term measurement of salinity and suspended sediment distribution in Deurganckdok.
 Monitoring near-bed processes (current velocity, turbidity, and bed elevation variations) in the
central trench in the dock, near the entrance as well as near the current deflecting wall location.
 Dynamic measurements of flow pattern, salinity and sediment transport at the entrance of
Deurganckdok.
 Through tide measurements of vertical sediment concentration profiles -including near bed
high concentrated benthic suspensions.

2.2. Description of the measurement campaign
2.2.1. Purpose of the measurement campaign
The purpose of the measurements was to determine the cross-section distribution of the
suspended sediment concentration, sediment flux, flow velocity and water discharge over a sailed
transect DGD during a complete tidal cycle. The final purpose is to make a water and a sediment
balance from the river Scheldt at Deurganckdok during a tidal cycle by integrating the water
discharge and sediment flux.
To get up a water and sediment balance at Deurganckdok, 3 transects were sailed during the
same tidal cycle on the 11th of March at the river Scheldt (Figure 2-4): at the entrance of
Deurganckdok (transect DGD), upstream of Deurganckdok (transect I) and downstream of
Deurganckdok (transect K). This report focuses on the through tide measurements at the entrance
of Deurganckdok (transect DGD) and the two others measurement campaigns are described in
IMDC reports 2008i and 2008j.

2.2.2. Measurement procedure
Flow velocity, Turbidity, Salinity and Temperature measurements were conducted on the 11th of
March from 7h00 MET until 20h00 MET. From the survey vessel Parel II a measurement cycle was
completed every 30 minutes. The vessel with a mounted ADCP sailed a fixed transect from the
right bank to the left bank and vice versa as a backup transect (Table 2-1). Profiles were gathered
to calibrate the ADCP transects for temperature, salinity and suspended sediment concentration to
be used in Sediview.
Two calibration profiles were collected for each transect (Table 2-2):
 One before sailing the transect at the bank where the start of the transect was
 One after sailing the transect at the bank where the transect ended
During these calibrations, a fish with a CTD-OBS was lowered to the bottom. The downcast was
interrupted at three depths, one in the upper half of the water column (between 4 and 7 m from the
water surface), one at 4 meters above the bottom and the last one at the water bottom. At the two
first depths samples were taken for calibration, and are used as ‘ground truth’ for all suspended
sediment concentration measurements (OBS and Sediview). The turbidity measurement at the
third depth is used to estimate the SS concentration at the bottom (see 4.2.4.1.2). The other
instruments logged continuously during the downcast. Conductivity, Temperature and Depth was
logged by the CTD-probe, while turbidity was recorded by the OBS.

2.3. The equipment
2.3.1. ADCP
The current measurements were conducted using an RD Instruments ADCP 600 kHz Workhorse.
For positioning the GPS onboard the vessel Scheldewacht II was used. For the measurement of
the heading a gyrocompass was installed.
This 600 KHz ADCP system was mounted on a steel pole underneath the central axis of the
vessel. The transducer set was looking vertically downwards to the bottom. Transceiver unit and
computer system were connected to peripherals such as the differential GPS-receiver, the heave
compensator and the gyrocompass.
During the measurements the ADCP constantly measured upstream from the vessel. The
acquisition software of Winriver was used. The main settings are given in Table 2-3.
Table 2-3: Main Configuration Settings of ADCP
Main configuration settings of ADCP 600kHz Worhhorse:
Cell depth: 0.5 m
Number of cells: 50
Number of Water pings per ensemble: 2
Number of Bottom Track pings per ensemble: 2
Time between ensembles: 0
Averaging: None
Speed of Sound: Fixed 1500 m/s
Salinity 0 psu
3-beam solution: enabled
2.3.2. OBS - CTD
A D&A type OBS 3A was used to measure depth, conductivity, temperature and turbidity.
Measured parameters by the OBS 3A sensor: temperature (°C), conductivity (µS/cm), absolute
pressure (m), turbidity (NTU).
On Parel II, the OBS 3A device was mounted on a tow fish. The resulting record is filled-up with
GPS-time, sample number, and planimetric position of the GPS-receiver. Sampling frequency is 1
reading per second.
The technical details on the OBS 3A are given in the winter calibration Report of the HCBS 1
measurement campaign. (IMDC, 2006a)
2.3.3. Pump Sampler
A water sampler was attached nearby the turbidity sensor taking water samples. Samples were
collected in 1 litre sampling bottles. The pumping speed of the water sampler was tested at the
start of the measurement campaign on board. Dye was used to time the duration between the
intake of the dye and exit at the sampling end of the sampler on board. The duration between
intake and exit at the end was 30 seconds.

be classified as spring tide.
3.2.2. Meteorological data
Meteorological data at Deurne was obtained from the Weather Underground website
(Wunderground, 2008).
The weather on the 11th of March 2008 was stormy and the wind blew from the west at an average
velocity of 22 km/h with maximal gust velocity of 67 km/h. The air temperature varied between 5
and 12°C. The sky was cloudy with precipitation.
3.3. Navigation information
An overview of the navigation at the measurement location is given in APPENDIX C.
3.4. Remarks on data
Shipwakes were removed from the data where possible. Transect 3095 was excluded for

4. PROCESSING OF DATASETS
4.1. Calibration of the OBS turbidity sensor
A crucial aspect of the accuracy and reliability of the data concerns the calibration of the OBS
turbidity sensor. The calibration of the OBS sensor is necessary to convert turbidity into
Suspended Sediment Concentration (SSC). We use here an in situ calibration, which is more
representative of the actual measurement conditions at that moment. At some depths water
samples were taken by the pump sampler and were analysed by a laboratory for SSC. These SSC
were used as ‘ground truth’ to calibrate the OBS turbidity sensor. The calibration curve can be
found in APPENDIX D.
4.2. Methodology of processing of the ADCP data with Sediview
DRL Software’s Sediview was used to process the ADCP data. Sediview is designed to derive
estimates of suspended sediment concentration throughout the water column using acoustic
backscatter data obtained by ADCPs manufactured by RD Instruments of San Diego, California.
4.2.1. Acoustic backscatter theory
The acoustic theory governing backscatter from particles suspended in the water column is
complex, but the following simplified formula serves to introduce the main factors that are relevant:
E = SL + SV + Constant - 20 log(R) - 2 w R
Where:
E
=
echo intensity,
SL =
transmitted power,
SV =
backscatter intensity due to the particles suspended in the water column,
w =
a coefficient describing the absorption of energy by the water,
R
the distance from the transducer to the measurement bin.
=
The term 20log(R) is a simple geometric function which accounts for the spherical spreading of the
beam. The constant is required because each ADCP has specific performance characteristics.
In order to measure the suspended sediment concentration in the water column it is necessary to
relate the backscattered sound intensity to the mass concentration in the water. For the purposes
of measuring solids concentration on site, it can be shown that the relationship is as follows
(derived from Thorne and Campbell, 1992 and Hay, 1991 in DRL (2003)):
Log 10 M r  dB  2r  w   s   K s S 1
Where:
M(r)
=
mass concentration per unit volume at range, r
S
=
relative backscatter coefficient
Ks
=
site and instrument constant
dB
=
the measured relative backscatter intensity (corrected for beam spreading)
w
=
water attenuation coefficient
s
=
sediment attenuation coefficient, which is a function of the effective particle size

Report 2.14: Through Tide Measurement Sediview 11/03/2008 Transect DGD
In this expression there are four unknowns: S, Ks, w and s. These parameters are to be
determined within Sediview (APPENDIX F).
4.2.2. Water sampling and transect sailing
To calibrate Sediview for suspended sediment concentration, two water samples are taken at the
beginning and at the end of each transect (see 3.1). Both samples are taken within the range of
reliable data of the ADCP. For the near-surface sample this means in bin 3 or 4, for the near-bed
sample this means at about one or two meter above the sidelobe.
Water sampling is done together with CTD-OBS measurement in order to have two independent
suspended sediment concentration measurements for each sample. OBS measurements were
compared to the water samples and recalibrated as mentioned in § 4.1. The water samples were
used for Sediview calibration, while cross-calibrated OBS measurements were used as a back up
check. The salinity and temperature was used to compute the acoustic water absorption (water
attenuation coefficient). All water samples were analysed as is described in 4.2.3.1.
4.2.3. Calibration for suspended sediment concentration within Sediview
4.2.3.1.
Calibration workset
The calibration workset consists of ADCP-files, sampling times, sampling depths, SSC obtained
from water samples and SSC, temperature and salinity obtained from CTD-OBS readings.
The suspended sediment concentration of the water samples was determined. One-litre samples
were filtered over a preweighed desiccated 0.45 micron filter, after which the filter is dried in an
oven at 105°C, cooled and weighted (NEN 6484).
4.2.3.2.
SSC calibration per ensemble pair
In the Sediview calibration process the following parameters must be defined: the site and
instrument constant (Ks), the relative backscatter coefficient (S) and the effective particle size per
ensemble-pair (near-surface sample and near-bed sample) in order to fit the Sediview-estimate
with the suspended sediment concentration of the water samples. These parameter sets may not
differ too much from the previous parameter sets, as the environmental conditions will not change
that much over a small time interval. To obtain a smooth progress in time of Ks, S and effective
particle size an iterative approach is used.
4.2.4. Sediview configuration
4.2.4.1.
Discharge and suspended sediment concentration estimates
The ADCP measures most of the water column from just in front of the ADCP to 6% above the
bottom. The shallow layer of water near the bottom is not used to compute discharge and
suspended sediment concentration due to side-lobe interference. When the ADCP sends out an
acoustic pulse, a small amount of energy is transmitted in side lobes rather than in the direction of
the ADCP beam. Side lobe reflection from the bottom can interfere with the water echoes and can
give erroneous data. The thickness of the side lobe layer is 6% of the distance from the
transducers to the bottom.
Near the banks the water depth is too shallow for the ADCP to profile.
For each of those unmeasured regions, Sediview will make an estimate of the discharges and
suspended sediment concentration. The measured and unmeasured regions in the cross section
are shown in Figure 4-1 and Figure 4-2.

4.2.4.1.1
Top/bottom estimates
The sediment concentration and discharge at the top of the water column is assumed to be the
same as the concentration and discharge in the first measured bin.
The sediment concentration between the bottom and the lowest valid bin is assumed to be an
increase of the lowest valid bin. The SSC increase between the lowest valid bin (position of the
sidelobe) and the bottom is calculated from the CTD-OBS profile, which was lowered in the
unmeasured sidelobe layer. The CTD-OBS profiles show that the bottom value of the SSC at the
calibration points transect I vary during a tidal cycle between approximately 99 and 194% of the
SSC-value at the position of the sidelobe. As the concentration grows approximately linear from
the lowest valid bin to the bottom, and as Sediview uses a constant concentration factor for these
deepest bins, we use a concentration factor that varies between 100 and 147% (Figure 4-3). An
overview of the used power concentration factor is given in APPENDIX F.

Edge estimates
The shape of the edges of the cross section is assumed to be near triangular due to the banks of
the river Scheldt. Five data ensembles are to be averaged to determine the left and right bank
mean velocities used for calculation of edge estimates.
The distance from start- and endpoint to the bank is calculated from the theoretical start- and
endpoint at the bank to the effective start- and endpoint. The theoretical points are taken at the
banks.

Contour plots of the transects
All contour plots show perpendicular and parallel projected values on the straightened sailed
transects. The heading of the straightened sailed transect is defined by picking 2 points in the
straight part of the line after having corrected the heading of the ADCP compass. The compass
offset is derived from a comparison of the ADCPs bottom track with the external GPS data.
4.2.5. Output
General transect information containing start-stop coordinates of each sailed transects with stop
time, track length and heading is given in APPENDIX A.
In APPENDIX G, four contourplots were generated for each transect showing the distribution of
suspended sediment concentration & sediment flux as well as the flow velocity perpendicular and
parallel to the transect. The following conventions were used:
 Distances on the X-axis were referenced to the starting point of the transect, the start of the
sailed transect is always at distance equal to zero.
 Left bank is always shown left, right bank on the right side. For transect DGD, left bank was
taken to be the western quay wall and the right bank to be the eastern quay wall considering
the dock as being a tributuary to the Scheldt river.
 Perpendicular flow velocities and fluxes are positive for downstream flow (ebb, out of
Deurganckdok), negative for upstream flow (flood, inbound).
 Parallel flow velocities are positive for flow going from the left bank to the right bank, and
negative for flow going from the right bank to the left bank.
 Absolute Depth is given in meters above TAW.
Also a depth-averaged velocity plot was generated for the flow velocity perpendicular to the
transect. (see APPENDIX G).
Tables in APPENDIX H give the values for discharges and sediment fluxes for the total crosssection and the average measured SSC is shown in APPENDIX I.

5. PRELIMINARY ANALYSIS OF THE DATA
5.1. March 11th 2008 survey
As Deurganckdok is situated along the part of the Scheldt river under tidal influence, it is subject to
complex current fields near its entrance. The measured current field shows a vortex pattern
depending on the tidal phase. During ebbing tide the vortex at the entrance of the dock is a
counter-clockwise one and during rising tide it is a clockwise one. This is shown in the contour
plots by inflow (negative) on the western side (left) and outflow on the eastern side of the entrance
during ebbing tide and vice versa for flooding tide. (APPENDIX G).
During slack water we see a current field with opposing current directions in the upper part of the
water column compared to the lower part of the water column. For high water we see inflow
(negative) near the bottom and outflow (positive) near the surface. This particular pattern is
probably an example of the expected salt density currents occurring near the entrance of
Deurganckdok. The same event is seen at low water when the dock contains waters of higher
salinity than the river; here we see an outflow near the bottom and inflow near the surface.
From the backscatter interpretation into suspended sediment concentration we see in general a
higher concentration during slack water and during rising tide compared to during ebb tide.
Considering the sediment fluxes APPENDIX J shows that incoming transport is dominating during
flood while a residual outgoing sediment transport can be observed from HW until the end of the
measurement.
It appears from the recorded data that the highest water velocities occur near the navigation
channel at about 1 hour before HW in which velocities exceed 1 m/s. The total calculated
discharge ranges between 19 and 931 m³/s.
The depth-averaged suspended sediment concentrations range from 41 mg/l up to 166 mg/l. The
highest SS concentrations occur about 1h00 after HW.
The maximum calculated flux during ebb occurs 1h10 after HW and is about 107 kg/s. During
flood, the highest flux is about -110 kg/s, 4h40 before HW.
5.2. Intercomparison with earlier surveys on November 17th 2005,
March 22nd 2006, September 27th 2006 and October 24th 2007
On November 17th 2005 (HCBS1), March 22nd 2006 (HCBS2 winter), September 27th 2006
(HCBS2 summer) and October 24th 2007 (DGD1) the same transect has been sailed during
through tide measurements, a description is given by IMDC (2005), IMDC (2006c), IMDC (2006d)
and (2008a). Conditions near the entrance of Deurganckdok have been simulated in Delft3D and
processed by IMDC (2006g) in order to compare simulation with observed data.
In order to make a comparison possible all results were referred to HW. The previous HCBScampaigns (HCBS1 & HCBS2-winter) show a comparable tidal amplitude (tidal coefficients about
0.75) corresponding to neap tide. The HCBS2-summer campaign (27/09/2006) and DGD1
campaign (24/10/2007) on the other hand, have a comparable tidal coefficient of about 1.02 and is
more corresponding to an average tide. The current campaign has a tidal coefficient of 1.14-1.19,
which is higher than the average spring tide (Table 3-2).

Report 2.14: Through Tide Measurement Sediview 11/03/2008 Transect DGD
It is important to underline that lower fresh water discharges from the tributaries were recorded
during the measurement campaigns (Figure 5-1, Figure 5-2, Figure 5-3 and Figure 5-4): on
17/11/2005 and 22/03/2006 the discharges prior to the measurements were about 90 m³/s; on
27/09/2006 about 30 m³/s, on 24/10/2007 about 45 m³/s and on 11/03/2008 about 285 m³/s.
The results presented in Figure 5-6 are based on a long-term simulation over a period of 30 year
(1971-2000) with the SIGMA-model for MKBA (IMDC, 2006g). The mean discharge is the annual
average ten days’ discharge, calculated with simulated long-term measurements. The high and low
discharges are also annual ten days’ discharges, and are calculated as mean discharge +2 and
mean discharge -2.

Figure 5-6: Mean fresh water discharge
The same circulation pattern as described above is found to have occurred at those days. In
Figure 5-7 and Figure 5-8 the five measurements have been compared for about 3h after high
water. Sediment distribution as well as current pattern in the cross section are almost identical for
the former campaigns whereas the current flow shows higher sediment distribution The western
side of the dock is situated at the left of these figures, the eastern side at the right.
In Figure 5-9 and Figure 5-10 the circulation pattern and sediment concentration have been
compared for the same days but at about 1h after high water. Again the current pattern is almost
identical on both days with a salt wedge intruding near the bottom of the dock and compensatory
outflow of fresher water near the surface.

The volume of water, crossing the dock’s entrance during flood or ebb on a measurement day,
was calculated by integrating the discharge curve during flood and ebb respectively. (Figure
5-11) and (Table 5-1) show the results. During flood on the 11th of March 2008, 5 642 000m³
water crossed the entrance and during ebb 11 872 000 m³. Comparing to the other campaigns,
the volume during ebb is a lot higher and during flood rather average. The (Table 5-1) shows
also the theoretical expected estimates of the volume during ebb and flood, which is result of a
multiplication of area of Deurganckdok and tidal difference. The expected volume of water
during ebb is smaller than the calculated water volume and during flood the expected volume is
more or less equal to the calculated volume. The differences mean that the calculated values
during ebb are probably an overestimation of the reality.

Report 2.14: Through Tide Measurement Sediview 11/03/2008 Transect DGD
The mass of the suspended sediment, crossing dock’s entrance during flood or ebb on a
measurement day, was calculated on a similar manner as the volume. The flux curve was
integrated (Figure 5-12) and (Table 5-2) show the results. During ebb on the 11th of March
2008, 655 tonnes SS crossed the entrance and during flood 1163 tonnes. 508 tonnes SS was
deposited in the dock during the tidal cycle. Comparing with other campaigns, 508 tonnes are a
high average (Table 5-2). Since flux is calculated with discharge and SS concentration, a similar
overestimation and underestimation as the water volumes will achieve in the calculated SS
masses.

R = ratio of measured conductivity to the conductivity of the Standard Seawater Solution
Conductivity Ratio R is a function of salinity, temperature, and hydraulic pressure. So that we can factor R into three parts i.e.
R = Rt x Rp x rt
R = C(S,t,p)/C(35,15,0)
C = 42.914 mS/cm at 15 deg C and 0 dbar pressure ie C(35,15,0) where 35 is the salinity
Ocean pressure is usually measured in decibars. 1 dbar = 10^-1 bar = 10^5 dyne/cm^2 = 10^4 Pascal.
