IDENTIFICATION OF GROUND WATER RESOURCE AND ITS CONSERVATION IN PARTS OF AURANGABAD, INDIA

摘要

Various geological and geomorphological factors play a major role at different levels in the occurrence, movement and potential of ground water in hard rock terrain of study area. The problems associated with the ground water resource development can be appreciated with reference to the topographic characteristics. Rainwater or surface water entering into the porous part of rock passes through a zone of aeration and the zone of saturation below is affected by the kind of geologic framework available and the hydraulics of water movement in sub-surface through the soil veneer. Thus, groundwater resources that develop in nature depending upon terrain conditions and the geological composition of terrain material are dissimilar in many respects. This aspect has been given importance for an understanding of the concept of groundwater resource development in the study area. Identification of the ground water potential zone in the study area was done on the basis of different hydro-geomorphic units. Accordingly five categories of groundwater potential zones were delineated as (i) Very Good (ii) Good (iii) Moderate (iv) Poor and (v) Very poor. An integrated approach of Remote sensing and GIS techniques has been used in this study. Methods of conservation of groundwater resource have been further suggested.
