This paper summarizes research on the Krishna River Basin in southern India, including physical and agricultural geography, remote sensing, hydrology, water management, and environmental
issues. Discharge from the Krishna into the ocean decreased rapidly from 1960-2003 due to irrigation expansion. Annual runoff to the ocean fell from a pre-irrigation average of 56 cubic
kilometers (km3)(1901-1960) to 13 km3 (1994-2003), despite no significant change in rainfall. By the late 1990s, the cumulative reservoir capacity in the basin approximated the annual runoff

The wetlands, a term which includes water bodies of different types ranging from lakes, estuarine area, and riparian flood plains to tidal mud-flats, play a vital role in ensuring

The geochemistry of ponds was studies around Jharia coal mining area. The high concentrations of cations and anions revealed the enrichment of pollution and thick population of E.coli bacteria. The pond waters are alkaline at all sampling sites and control the weathering pattern and availability of dissolved solids in Jharia pond water.
