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

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...

Variability of Sediment Removal in a Semi-Arid Watershed

Flood-Runoff in Semi-Arid and Sub-Humid Regions, a Case Study: A Simulation of Jianghe Watershed in Northern China

This paper presents a modeling application of surface runoff using the Hydrologic Modelling System (HEC-HMS). A case study was carried out for the Jianghe watershed, a typical semi-arid and sub-humid geo-climatic region in northern China. Two modeling schemes using different descriptive sub-mechanism models provided by HEC-HMS for runoff volume, direct runoff and routing (channel flow) were inv...

Estimating river suspended sediment yield using MLP neural network in arid and semi-arid basins Case study: Bar River, Neyshaboor, Iran

Abstract Erosion and sedimentation are the most complicated problems in hydrodynamic which are very important in water-related projects of arid and semi-arid basins. For this reason, the presence of suitable methods for good estimation of suspended sediment load of rivers is very valuable. Solving hydrodynamic equations related to these phenomenons and access to a mathematical-conceptual mode...

Modeling of Rainfall-Runoff Relationship in Semi-Arid Watershed in the Central Region of Jordan

As a result of quick progression in computer and information technologies, computer modeling has become a vital tool in watershed research and management practices. Stanford Watershed Model (SWM) is an integrated physically based Watershed model that can be used to simulate water flow stream/canal network and overland runoff, interflow and evaporation by considering the interaction between surf...

Comparing 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...
