WEIGHTED OVERLAY ANALYSIS FOR DELINEATION OF GROUND WATER POTENTIAL ZONE: A CASE STUDY OF PIRANGUT RIVER BASIN

Groundwater is the major natural resource of drinking water in both urban and rural India. Besides, it is an important source of water for the agricultural and the industrial sector. The aim of the present study is to delineate ground water potential zone and identifying land suitability for improving agricultural productivity over the area of Pirangut river basin catchments using remote sensing and GIS technology. GIS technology is helpful to prepare a various base layer and maps viz. such as, geology, geomorphology, Land Use Land Cover, slope, digital elevation model(DEM), worthy - non worthy, drainage line density, rainfall runoff, soil cover depth, drainage stream order, well density, ground water fluctuation, village proximity. GIS techniques were used for Weighted overlay analysis and integrated with multi-criteria analysis. This all layers are generated using a Light Imaging Self Scanner (LISS IV) sensor satellite image with 5.6m resolution and Survey of India (SOI) topographical maps with 1:50000 scale. Morphometry technique is performing to access the geo hydrological qualitative and quantitative characteristics of drainage basin. Hydro geological technique used to determine ground water fluctuation or flow of ground water conducting well location on field with well inventory analysis. The final groundwater potential map was prepared by assigning appropriate weightage to different thematic maps and superimposed by weighted overlay method....

GEOSPATIAL TECHNIQUES IN LAND RESOURCE INVENTORY AND MANAGEMENT: A REVIEW

Available natural resources govern the basic development of any country. Among many; land and water resources are most important that support survival of individuals on the earth. Due to rapid increase in population, these resources are over stretched often leading depletion constantly. In recent times, geospatial techniques are being effectively used for more precise mapping and judicious management of land resources. Geospatial technology concerned with spatial information about features at a place or, in space, collected in real time. Geospatial techniques is the combination of Remote Sensing (RS), Geographic Information System (GIS), Global Positioning System (GPS), cartography, and spatial statistics that capture, store, manipulate and analyze to understand complex situations of environment and solve the problems for sustainable development. In the study an attempt has been made to review the application of geospatial techniques in land resource inventory, analysis, mapping and management. The review shows that these techniques have immense potential and being used in various aspects of land resources inventory such as digital terrain analysis, soil resource inventory, land use/land cover mapping, wastelands mapping, water resources and environmental management. Keywords Geospatial techniques, land resource inventory, remote sensing, GIS, GPS...
