GROUND WATER PROSPECT OF SURENDRANAGAR DISTRICT
Presented byAlka Beura & Nikita Raval
AIM The Aim of present project work is to find out ground water prospect of surendranagar district of Gujarat by using Remote sensing and GIS technique.
OBJECTIVE ďƒ˜
The study has been carried out with the following objectivesLULC and geomorphology mapping of the study area by using LISS-III satellite imageries in Remote Sensing and GIS environment. Using GIS tool (Union & resolve) to generate ground water prospect of Surendranagar district.
INTRODUCTION
Surendranagar is located at 22° 43’ 53” N latitude and 71° 38’ 12” E longitudes, belongs to the semi-arid region of Gujarat .
The district is of area 10436.30 Sq Km having population 15,15,147.
The annual average rainfall is very low.
Groundwater is generally saline. Irrigation is totally dependant on rain.
The district has lowest amount of industrial investment, due to scarcity of water.
METHODOLOGY
Selection of area .
Geo referencing of available satellite imagery (LISS-III of DOP 26 Jan 2010) .
Imagery interpretaton in Arc GIS environment to produce:Base Map (Transport, Water body & drainage) LULC Map Geomorphological Map
BASE MAP
ADMINISTRATIVE MAP
LISS-III DATA (SUBSET)
TRANSPORT MAP
DRAINAGE MAP
WATER BODY MAP
LAND USE LAND COVER ďƒ˜
Land use includes, everything land is used for by the residents, from farms to hospitals, parks and grave lands. Land cover refers to, vegetation and artificial construction covering the land surface . land use describes how a parcel of land is used, whereas land cover describes the materials, that are present on the surface.
LULC MAP
GEOMORPHOLOGY Definition Geomorphology is an area of geology concerned with the study of landforms, with the forces and processes that have shaped them, and with the description and classification of various physical features on Earth. ďƒ˜
Different classes of geomorphology are depicted in geomorphological map.
GEOMORPHOLOGICAL MAP
METHODOLOGY ďƒ˜
Using union tool of Arc GIS to generate Union of LULC & Geomorphology layer.
METHODOLOGY
Generation of Matrix from Union.
METHODOLOGY
Assigning of GWP (Ground water prospect).
METHODOLOGY ďƒ˜
Calculation of resultant ground water prospect values in union file .
METHODOLOGY ďƒ˜
The dissolving process of GIS on ground water prospect values of union file is carried out in order to generalize the GWP polygons.
ďƒ˜
The statistic type used to summarize attributes is added to the output features class as a single field.
METHODOLOGY ďƒ˜
Generation of final output i.e. ground water prospect map.
CONCLUSION ďƒ˜
The study has shown that by using the Remote Sensing and GIS technique, the GWP map of selected Surendranagar district could be generated with less effort and in less time along with limited field checks as compared to the conventional methods.
