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...

متن کاملUncertainty and sensitivity analysis of runoff and sediment yield in a small agricultural watershed with KINEROS2
Using the Monte Carlo (MC) method, this paper derives arithmetic and geometric means and associated variances of the net capillary drive parameter, G, that appears in the Parlange infiltration model, as a function of soil texture and antecedent soil moisture content. Approximate expressions for the arithmetic and geometric statistics of G are also obtained, which compare favourably with MC gene...
متن کاملGeographic information system and process-based modeling of soil erosion and sediment yield in agricultural watershed
BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...
متن کاملmodeling of sediment yield and bicarbonate concentration in kordan watershed
in the present study, the soil and water assessment tool (swat 2000) model was tested on both a monthly and yearly basis and applied to the kordan watershed, located in iran. the main objective of the research was to assess the accuracy of the model in sediment-yield and surface water bicarbonate concentration estimation. the attributes of sub-watersheds, tributary channels and the main channel...
