WebbAs mentioned above, we used a dataset obtained from standard erosion plots to test the performance of the RUSLE K-factor, USLE K-factor, and some PTFs (Table 2) that have been developed in recent years in the Middle East. Fig. 5 shows the measured K-factor using standard erosion plots versus the predicted K-factor using the PTFs.As shown in … http://ecoursesonline.iasri.res.in/mod/page/view.php?id=1912

WebbAs a rule of thumb, if no signs of deposition are present on a concave slope, assume that deposition begins at the location where the steepness is 1/2 of the average steepness of the concave area. Another difficulty is determining if a channel is a concentrated flow channel that ends a RUSLE slope length. WebbThe effect of topography on erosion in RUSLE is accounted for by the LS-factor. Erosion increases as slope length increases, and is ... origin of overland flow to the point where either (1) the slope gradient decreases enough that deposition begins or (2) runoff becomes concentrated in a defined channel. Surface runoff will usually concentrate ...
