| Abstract | Solapur District is a district in Maharashtra state of India, with Solapur city as its headquarters. It's located on the southeast edge of the state and lies entirely in the Bhima and Sina river basins. Solapur district is located in a monsoonal rain shadow area of Maharashtra and has an average annual rainfall of approximately 584.3 mm. However in 2025 September, it received about 70-to 100 mm in a day at different places. Simultaneously in the upstream basin?s recharge area, the rain spells were abnormally heavy and sudden. The medium irrigation projects on main 3-4 tributaries overflowed and discharged water, into Sina River haphazardly. Rainfall data analysis for Solapur district in 2025 monsoonal period indicates periods of extremely heavy cyclonic rains, especially in last week of September 2025, that resulted in serial flooding, crop damage, and high water discharge from medium and major dams in both the river basins. In recent decades the ephemeral Sina River was converted into perennial link canal, through Bhima ? Sina link canal project, with aim to distribute water from Ujani Dam to drought prone region around Sina basin- which is actually part of major Bhima basin. This has effected and affected the land use and geohydrological properties around, in the Sina River basin area. The Sina River joins Bhima River, nearly in right angle, at the state boundary of Maharashtra and Karnataka. Bhima was flowing beyond its extreme capacity and acted as bund for Sina excess water mixing at the confluence, resulting in backwater voluminous historic floods, in the broader flood plain areas of Sina River. Attempts have been made to analyze holistically, through detail studies of the various geological, geomorphological, geohydrological and man imposed activities in the total Sina River basin, to investigate the causes and further proposing suggestions to mitigate the problem solution for minimizing the flood hazards in future. |
