This paper describes the physical geography and hydrology of the Krishna Basin, including runoff production and a basic water account based on hydronomic zones. More than 50 percent of the basin's irrigated area is groundwater irrigation, which is not currently included in inter-state allocation rules. Future water allocation will require inclusion of the interactions among all irrigated areas, including those irrigated by groundwater and surface water.application/pdfOpen Accessriver basinsphysical geographyclimatestream flowhydrologyrainfall runoff relationshipsevapotranspirationirrigation programswater allocationwater transferenvironmental effectswater qualityReport
