One of the most pressing global issues currently being faced by the mankind is the increase in world’s population and its impact on the availability of freshwater.

As ground water forms an important component of the total water supply (e.g. about 90% in rural areas and 30% in urban areas of India (NRSA 2000).

The aquifers are often under stress, resulting in lowering of the water table and drying up of springs and wells at many places.

This has attracted the attention of find appropriate and efficient techniques to locate potential sites for drilling of wells and for putting up artificial recharge structures in order to ensure sustainability of well yields and counter the problem of water table depletion.

Introduction

Remote Sensing (RS) and Geographic Information System (GIS) techniques have emerged as handy, complementary tools in assessing, monitoring and conserving ground water resources.

Ground prospects zonation means identifying and mapping the prospective groundwater zones in an area by qualitative assessment of the controlling and indicative parameters.

controlling parameters Lithology (texture, origin, distribution), Geological Structures (bedding, faults, fractures, shear zones, folds) Geomorphology(origin and assemblage of different landforms, depth of weathering, thickness of deposited material, etc.) Hydrology (surface water bodies, surface and ground water irrigated areas, depth to water table and fluctuation, well yields and rainfall).

• Developing thematic maps related to geomorphology, lithology, landuse,

rainfall, slope and groundwater level for an area.

• Generating of groundwater prospects mapping for an area.

• Recommending the groundwater management plans based on the

groundwater prospects maps developed

Objectives

Naveenkumar et al., (2015) • The objective of this study is identifying the groundwater availability for agriculture

in a part of Malaprabha river basin. • Remote sensing data and Geographic Information System (GIS) are used to locate

potential zones for groundwater in the part of Malaprabha river basin. • Various maps are prepared using remote sensing and ArcGIS. It determines the

influence of each parameter on the potentiality. • Each category of a particular map is assigned ranks according to their suitability and

each parametric map is given certain weightage based on its influence on the ground water availability.

• Higher ranks are given to most suitable category and ranks decrease as per the decrease in suitability.

• Find that area having moderate ground water prospect zone.

Literature review

paper deals with the preparation of ground water potential zones for Bengaluru urban District Karnataka.The various thematic maps of geomorphology, geology, lineament density, drainage density, slope and landuse/landcover (LULC) were generated using the resourcesat data and survey of India (SOI) toposheets of scale 1:50000.

The thematic layers will be integrated using ARCGIS-10 software to identifying the overlay analysis & yield of the ground water potential zone map of the study area.

ground water potential zones are identified in to 5 classes namely ‘good’, ‘good-moderate’, ’moderate’ , ‘moderate-poor’ and ‘poor’.
