Comparison of two MPSIAC and MMF models in soil erosion mapping of Ardebil Agh Gouni watershed
Extended abstract 1- Introduction Soil erosion is the most important cause of land degradation and the cause of water loss, soil loss, sedimentation in water resources, and maximum flood intensification (Liu et al., 2019). Models are the most important tools for estimating and mapping of erosion at the watershed level. As the experimental models are dependent on used coefficients and region c...
متن کاملComparing WEPP and Hydro Physical Models to Estimate Soil Erosion and Sediment Production: A Case Study of Chardavol Watershed
Extended abstract 1- Introduction Soil erosion and sediment production include fundamental limitations in the use of soil and water resources. The sediment yields watersheds in addition to the loss of soil fertility, causing water quality reduction. Therefore, evaluation processes that govern their behavior to better understand and assess the systems of watershed management practices are imp...
متن کاملassessing the effects of erosion on long-term soil productivity potential in kohin watershed, ghazvin province
maintaining soil productivity is one of the key factors in sustainable agriculture. soil erosion reduces soil productivity over a long-term period of time. therefore, determining soil erosion tolerance is necessary for sustainable agriculture production. in this study, the long-term effects of erosion on soil productivity in the typical kohin watershed were evaluated. the soil productivity inde...
متن کاملEstimation of Soil Erosion in Sefidrood Watershed by Emphasis on the Role of Landforms
Among the various processes that destroy lands, soil erosion is a complex and hazardous environmental process that constitutes a serious threat to preservation of soil and water resources in Iran and has inflicted its negative effects on the vital ecosystem with the intensified utilization of nature by human beings. The present descriptive and analytic research employed the PSIAC model to study...
متن کاملEffect of soil erosion on available phosphorus losses in a Hyrcanian watershed
One of the most important main environmental problems is soil erosion and its affects. Eutrophication, low oxygen levels and `high nutrient (nitrogen and phosphorus) concentrations in reservoirs, channel and other water courses, is a common water pollution feature. Phosphorus (P) is one of the major plant nutrients and also the major nutrients controlling eutrophication of surface water. The ai...
