Introduction
Wetlands are highly productive
ecosystems that afford various ecosystem
services.
The significant natural reservoirs forms a large proportion of water in
the primary wetlands thus their identification and management
should be the focus for sustainable wetland ecosystem and
economic services.

Function Mapping
Tool to identify recharge zone
The goal of the mapping is to provide a
product to aid watershed managers,
state and local agencies and
emergency responders to deal with
water management issues.
Problem Statement
Understanding the continue flow of stream and identification of the
recharge point is necessary, to focus on the regulation and management
of the wetland.
But
the occurrence of recharge point
in mountain 3 is unidentified
the studies of stream
recharge zones and
discharge points are not
focused in the wetland area
Objectives
To identify recharge
zone and discharge
points of Khotokha
wetland from mountain
3.
To identify
management regimes
for Khotokha wetland.

To recommend
strategic plans for
management of
Khotokha wetland
Methods and Materials
Sampling
samples were selected through purposive
sampling and opportunistic survey of the
outcrops while walking through the terrains of
mountain 3.
Sample size
24 outcrop readings
were taken
from an unknown
population.

Mountain 3
Data collection
SW Map
To record
elevations,
gradients (latitude
& longitude).
RockD
To measure strike
and dip direction.
Clinometer
To measure slope
Additionally rock types and any noticeable special features (eg. Fire
burnt and totally exposed) were also recorded.
Data analysis
The Following Apps and software were used;
Covert the excel data into KML
Google Earth Pro:
• Collected data was imported.
• All 24 rock outcrops were plotted on. the map using the add
path tool, strike and dip direction were drawn for each
point.
• The outline was drawn to adjoin it with
the points.
.
• Using the Snip tool took the map picture
CorelDRAW:
•
•
•
•
Import the Snipped file in the CorelDraw
Represent the landscape through elevation view
Draw the Dip amount for each point
Group all the points and using Smart Fill, assign distinctive colours to
different polygons
• Extrude the map into 3-D
Once the geophysical parameters are standardized through lithology
information, the observed variations are interpreted to reflect the geological
variations.
Result
The occurrence of recharge point in mountain 3 is unidentified
The potential zones for ground water recharge were explored by
analyzing the parameter geology through geospatial technology.
The results indicate that lithology is the significant variable controlling
the recharge of the study area.
Dip directions of the mountain 3 were mostly towards NNE
which contribute spring water to the wet land.
The plot 4 to 20 was granite schist, plot 21 was muscovite and
plot 2 & 3 falls in the recharge zone.
The study revealed that the mountain 3 contributed springs to
the wetland

Conclusion
• The geometry of the area inferred using above mentioned
tools.
• The recharge zone identified aided in prescribing the
management regimes.
Recommendations
Areas above and below the
recharge zone should be
included for management.
Quantify the significance of
the contribution of recharge
point to the RAMSAR site
Timber extraction near the
recharge zone area to be
restricted.
Other factors such as drainage
density and land use
landcover to be considered.
