The estimation of sediment yield from the catchment helps in understanding the morphodynamic condition of the river. The present study deals with the application of soil erosion model in particular the RUSLE model and integrated with Sediment Delivery Ratio (SDR) to estimate the average annual sediment yield from the year 2011 to 2020 at the different gauging stations of Seonath River basin. Seonath River in Chhattisgarh state is one of the major left joining tributaries to the Mahanadi. It has a catchment area of about 33,000 km2. The average sediment yield at the gauging station of the Seonath River at Jondhara, Kotni, and Simga is about 3.43, 0.50, and 1.09 million tons (MT) respectively. Andhairkore and Ghatora gauging station on river Hamp and Arpa respectively, which is a tributary of Seonath River shows annual average sediment yield of about 0.71 and 0.22 MT respectively. The study concludes with a depiction of percentage change in sediment yield obtained from RUSLE model from the year 2011–2020 with respect to previous year. The change varies from −30% to +50% at all the gauging sites of Seonath River basin.

摘要

The estimation of sediment yield from the catchment helps in understanding the morphodynamic condition of the river. The present study deals with the application of soil erosion model in particular the RUSLE model and integrated with Sediment Delivery Ratio (SDR) to estimate the average annual sediment yield from the year 2011 to 2020 at the different gauging stations of Seonath River basin. Seonath River in Chhattisgarh state is one of the major left joining tributaries to the Mahanadi. It has a catchment area of about 33,000 km2. The average sediment yield at the gauging station of the Seonath River at Jondhara, Kotni, and Simga is about 3.43, 0.50, and 1.09 million tons (MT) respectively. Andhairkore and Ghatora gauging station on river Hamp and Arpa respectively, which is a tributary of Seonath River shows annual average sediment yield of about 0.71 and 0.22 MT respectively. The study concludes with a depiction of percentage change in sediment yield obtained from RUSLE model from the year 2011–2020 with respect to previous year. The change varies from −30% to +50% at all the gauging sites of Seonath River basin.
