Evaluation of Runoff‧Peak Rate Runoff and Sediment Yield under Various Rainfall Intensities and Patterns Using WEPP Watershed Model

Runoff and sediment yield modeling using WEPP in a semi-arid environment (Case study: Orazan Watershed)

Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...

Evaluation of soil erosion and sediment yield estimation various empirical model by observation values (Case study: Babolroud watershed, Mazandaran Provienc)

In this study where done in Babolroud basin, seven models include MPSIAC, EPM, Fournier, Douglas, Kirkby, Geomorphology and Hydrophysical was evaluated to determine the best model  for estimation of soil erosion and sediment yield. These models have not been compared together as integrated in the previous researches. The zoning soil erosion intensity map was prepared for each model using GIS. T...

Investigation of Effective Factors on Runoff Generation and Sediment Yield of Loess Deposits Using Rainfall Simulator

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
