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 I/RA/11283/07.089/MSA 1 versie 1.0 - 12/08/08 IMDC NV i.s.m. WL|Delft Hydraulics Opvolging aanslibbing Deurganckdok en Gems Report 2.13: Through Tide Measurement Sediview 11/03/2008 Transect K 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 2.13, 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.

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 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 I/RA/11283/07.089/MSA 6 versie 1.0 - 12/08/08 IMDC NV i.s.m.

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. Monitoring dredging activities at the entrance channels towards the Kallo, Zandvliet and Berendrecht locks as well as dredging and dumping activities in the Lower Sea Scheldt and Deurganckdok in particular. In situ calibrations were conducted on several dates to calibrate all turbidity and conductivity sensors. I/RA/11283/07.089/MSA 7 versie 1.0 - 12/08/08 IMDC NV i.s.m.

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 K 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 downstream of Deurganckdok (transect K) and the two others measurement campaigns are described in IMDC reports 2008j and 2008k. th Figure 2-4: Map of sailed transect and calibration points at Deurganckdok on 11 of March 2008 I/RA/11283/07.089/MSA 8 versie 1.0 - 12/08/08 IMDC NV i.s.m.

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 Veremans 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 short 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. th Table 2-1:Transect of the Flow Measurements on 11 of March 2008 (UTM31 ED50) Measurement location Transect I Transect DGD Transect K Left Bank Easting 590 318 588 541 588 484 Left Bank Northing Right Bank Easting Right Bank Northing Avg Length [m] 5 683 302 5 684 527 5 684 924 590 771 588 765 589 775 5 684 557 5 684 056 5 685 384 1057 521 1371 Avg Course [degr.] 25 335 70 th Table 2-2: Positions of the calibration points for 11 of March 2008 during flood and ebb.

ADCP The current measurements were conducted using an RD Instruments ADCP 600 kHz Workhorse. For positioning the GPS onboard the vessel Veremans 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.

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 Veremans the OBS 3A device was mounted on a towfish. 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 24 seconds. Around 8h45 MET the hose was screwed into the propeller so a new sampling period had to be measured with the shorter hose: 18 seconds. I/RA/11283/07.089/MSA 10 versie 1.0 - 12/08/08 IMDC NV i.s.m.

Measurement periods At Deurganckdok ADCP tracks were sailed once every 15 minutes for 13 hours, in total 52 crosssections. Calibration profiles were taken at 2 locations (left bank, right bank). During every cycle, 1 calibration profile was taken serving as the second calibration of the previous transect and as the first calibration point of the current transect, resulting in a total of 42 profiles. APPENDIX A gives the start and end points of the tracks, the sailed length and the course. 3.2. Hydro-meteorological campaign conditions during the measurement 3.2.1.

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.

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 covert 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 I/RA/11283/07.089/MSA 13 versie 1.0 - 12/08/08 IMDC NV i.s.m. WL|Delft Hydraulics Opvolging aanslibbing Deurganckdok en Gems Report 2.13: Through Tide Measurement Sediview 11/03/2008 Transect K 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. 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. I/RA/11283/07.089/MSA 14 versie 1.0 - 12/08/08 IMDC NV i.s.m.

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 K vary during a tidal cycle between approximately 99 and 328 % 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 214% (Figure 4-3). An overview of the used power concentration factor is given in APPENDIX F. I/RA/11283/07.089/MSA 15 versie 1.0 - 12/08/08 IMDC NV i.s.m.

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 0, 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 0).

PRELIMINARY ANALYSIS OF THE DATA 5.1. March 11th 2008 survey It appears from the recorded data that the highest water velocities occur near the navigation channel at about 3 hours after HW in which velocities exceed 1 m/s. The total calculated discharge ranges between 350 and -18885 m³/s. Average cross-section concentrations vary from about 172 up to about 612 mg/l. The highest measured concentration from a watersample is 940 mg/l (recorded near the right bank at 7 meters deep about a 5h25 after HW). 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. The maximal calculated flux during ebb occurs around 4h15 after HW and is about 6463 kg/s. During flood, the highest flux is about -5812 kg/s, 0h51 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 5HCB2 winter), September 27th (HCBS2 summer) and October 24th 2007 (DGD2, current report) the same transect has been sailed during through tide measurements, a description is given by IMDC (2005), IMDC (2006c), IMDC (2007c) and IMDC (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. It is important to underline that lower fresh water discharges from the tributaries were recorded during the former measurement campaigns (Figure 5-1, Figure 5-2, Figure 5-3 and Figure 5-4): on 16/11/2005 the discharges prior to the measurements were about 230 m³/s; on 22/03/2006 and 23/03/2006 about 95 m³/s and on 27/09/2006 and 28/09/2006 about 40 m³/s. All measurement days correspond to the mean discharge -1, which is rather low (Figure 5-5). The results presented in Figure 5-5 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. I/RA/11283/07.089/MSA 19 versie 1.0 - 12/08/08 IMDC NV i.s.m.

WL|Delft Hydraulics Opvolging aanslibbing Deurganckdok en Gems Report 2.13: Through Tide Measurement Sediview 11/03/2008 Transect K The fluxes, total discharges and suspended sediment concentrations, of all measurement campaigns at Liefkenshoek are illustrated in Figure 5-6, Figure 5-7 and Figure 5-8. It can be seen that the discharges, fluxes and SS concentrations of this campaign are higher than the previous campaigns. The volume of water, crossing transect K during flood or ebb on a measurement day, was calculated by integrating the discharge curve (Figure 5-7) during flood and ebb respectively. Table 5-1 shows the results. During flood on the 11th of March 2008, 177.653.000 m³ water crossed transect K and during ebb 212.191.000 m³. Comparing to the other campaigns, the volume during ebb is extreme low and during flood a lot higher. The stormy weather causes this phenomenon. The mass of the suspended sediment, crossing transect K during flood or ebb on a measurement day, was calculated on a similar manner as the volume. The flux curve was integrated (Figure 5-6) and (Figure 5-8) shows the results. During ebb 11th of May of 2008, 88.476 tonnes SS crossed the transect K and during flood 52.743 tonnes. 35.733 tonnes SS was deposited in the dock during the tidal cycle. Comparing with other campaigns, 35.733 tonnes are a lot. (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.
