Water Quality Status And Geo-spatial Mapping Of Daharabi Dam

Abstract

Water is essential for life but this resource is becoming scarce due to overexploitation of the resources on account of competing land use patterns, degradation of forest cover and lack of conservation in its use. Water use would be beneficial when managed properly amongst the competing interests. Spatial information systems commonly referred to as Geographic Information Systems (GIS), have emerged as a potent investigative tool in securing a layered analysis of the earth resources, land and water included. A study was carried out to evaluate the surface-water quality in the Dharabi dam with the help of GIS and remote sensing techniques. To monitor the water quality of the dam in terms of various physiochemical parameters. The results of the study demonstrated that the physicochemical quality of water was satisfactory where whereas the Biological quality of water was unsatisfactory, while 50 to 87.5% of the samples contained bacteriological contamination before monsoon. This percentage rose to 98.5% after the monsoon. Lack of proper management practices for dam and control of sewage and agricultural discharge into the surrounding locality is also linked with the deterioration of water quality. It is recommended to carry out Mitigation measures to control the quality of water
