Abstract The study was conducted, in Sonwal watershed of Shahada taluka, Nandurbar district, Maharashtra with an area of 9934 ha, located in 74° 53´ to 74°75´ N and 21°54´ to 21°62´ E for estimation of sediment yield using Garde’s method. The observed sediment yield of the Sonwal watershed in 2002-03 was 5.88 t/ha/yr. However, it was found 10.22 t/ha/yr in 2008-09, with an increase of 4.34 t/ha/yr. The estimated sediment yield of the watershed for the year 2002-03 using Garde’s equation was found to be 12.37 t/ha/year with per cent change in observed and estimated sediment yield, 110.37. The estimated sediment yield of the watershed for the year 2008-09 was found to be 14.82 t/ha/year with per cent change in observed and estimated sediment yield, 45. To reduce the rate of increase of sediment yield, the agriculture area needs to be increased by decreasing the wastes land besides, the watershed development program need to be implemented effectively to reduce the sediment yield or soil loss. Keywords: Sonwal watershed; Garde’s method and sediment yield.
