REMOTE SENSING AND GIS BASED WATER QUALITY ESTIMATION FOR THIMMAPALLY WATERSHED

Groundwater resources are dynamic in nature as they grow with the expansion of irrigation activities, industrialization, urbanization etc. As it is the largest available source of fresh water lying beneath the ground it has become crucial not only for targeting of groundwater potential zones, but also monitoring and conserving this important resource. The expenditure and labour incurred in developing surface water is much more compared to groundwater, hence more emphasis is placed on the utilization of groundwater which can be developed within a short time. In the study about the area we have learned about the archean rocks, structure, sub-surface lithology, geomorphology, hydrology, identifying the ground water potential zones
