Abstract

In India, about 50 per cent of total irrigated area and 60 per cent of irrigated food production depends upo resources. Moreover, with 16 per cent of world population, 2.45 per cent of the world's land area and 4 per cen water resources, our country is now facing water crisis, which will be more acute by 2025 with per capita wate about 1450 m3 (where, more than 1700 m3 is considered to be the per capita water availability without any Therefore, integrated management of groundwater resources will not only ensure availability of drinking water b agricultural production and productivity. In this context, a Ground Water Information System (GWIS) interface, using the built-in macro programming language of ArcGIS®. The developed GWIS performs three basic function assess regional ground water availability based on water table fluctuation methods and rainfall infiltration meth potential ground water recharge zones based on topology, geology, land use and hydrological responses of the r, propose suitable recharqe technique based on the regional parameters and quantify the recharge for replenish water up to the desired level. The information system was coded in Visual Basic for Applications (VBA) built in rr of ArcGIS® 8.3 using the established recharge technique information and feature class coverage maps of the str hydrological parameters, aquifer geological parameters, soil and land use parameters and ground water tabl GWIS was customized as an interface tool in ArcGIS® 8.3 and was applied to the delineated IARI watershed reg for locating potential recharge zones and water harvesting structure sites for water table augmentation. Howeve tool can be applied to any study region with available input parameters to generate information on ground water recharge requirements for integrated water resources management.
