Garde’s Model was used for sediment yield estimation in Sonwal watershed, of Shahadataluka, Nandurbar district, Maharashtra with an area of 9934 ha, located in 74° 53´ to 74°75´ N and 21°54´ to 21°62´ E. The observed sediment yield of the Sonwal watershed in 2002-03 was 5.88 t/ha/yr and 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 percent 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 percent change in observed and estimated sediment yield, 45. The rate of increase of sediment yield can be reduced by increasing agriculture area and reducing the area under wastes land besides, besides the watershed development program need to be implemented effectively to reduce the sediment yield or soil loss.
