The importance of erosion in relation to variability of water and soil losses from a parcel of land can be revealed in the measurements of the sediment yield and runoff under a comparable collection tanks within the land. This experiment is aimed at assessing the variability of runoff and soil loss within and among runoff plots. This study involved three plots of measurement out of six plots (40 m x 3 m each) randomly distributed over a land area of 0.072 ha. The study was conducted on a 7% slope experimental plot, during the 2007 raining season.Runoff and soil loss were measured after every...
