Effect of Land Slopes on Soil Erosion under Simulated Rainfall

Abstract

This study was aimed at understanding the effect of land slopes on soil erosion under simulated rainfall
characteristics. The experimental set up consisted of three units viz., the runoff plot, the rainfall simulator and the runoffsediment collection unit. Twelve runoff plots with twelve different slopes of 1.5, 2.0, 2.6, 3.0, 3.2, 4.0, 5.0, 6.0, 9.0, 10, 12
and 13 per cent in different locations, each plot with a size of 2 x 1.5 m were prepared. The results showed that soil loss
and runoff was found to increase with increase in land slopes and there were no much variations on runoff and soil loss
at 6 to 10 per cent land slopes
