| Summary: | also developed to offer users a complete tool set. A new analyzed. This analysis indicates that a coaser and climatic factors have direct effects on soil loss. Slope based on each HRU. RUSLE and MUSLE models were integrated classification scheme had higher soil loss prediction. classified using three different schemes and inputted into developed in this study. This procedure calculated the slope Empirical erosion models are often used to estimate the soil equation (RUSLE) predicts the annual average soil erosion. erosion and sediment yield. Revised universal soil loss experiment units in this study. Soil erosions were predicted features that affect soil loss. Classifying slope gradient GIS to decompose watershed into hydrologic response units. gradient and slope length are two most important topographic length of each HRU and could compensate the deficiencies of Model predictions were made for each classification scheme. models (RUSLE and MUSLE) vary when different criteria are Modified universal soil loss equation (MUSLE) predicts parameters and integrate soil loss equations with GIS are predictions. This thesis studied how the predictions of previous methods. previous watershed erosion studies. HRU were used as the procedure using the flowlength function of GIS was also Procedures to develop hydrologic response units, model input provide a better consideration of spatial variability of the sediment yield on a storm event base. The land attributes soil erosion processes. HRU were used as analysis windows in such as topographic features, soil types, vegetation covers The resulting three different sets of predictions were used to classified the slope gradients. Decomposing a Water erosion is a major cause of watershed degradation. watershed into a set of hydrological response units (HRU) can with a geographic information system (GIS). Slope was with different criteria may lead to different model |
