The article proposes a model for integrated management of a regulated watershed. In such systems, it is important to take into account not only the discharge released at the reservoir, but also the natural flows due to rainfall. The proposed model incorporates both inputs, and can be refined by considering different numbers of sub-basins corresponding to tributaries of the river. We discuss the...

degradation model was introduced as an instrument of environmental impact assessment (eia) in iran. several methods are introduced in rapid environmental assessment, but none of them have evaluated landscape level. thus, the main objective of this research is to introduce a new spatial method for eia by using landscape metrics. a benefit of rapid assessment by using ecological landscape metrics...

in this study, the process-based watershed model, soil and water assessment tool (swat), was used for simulating hydrology and sediment transport in the gharesou watershed and for identifying critical areas of soil erosion and water pollution. after model calibration and uncertainty analysis using sufi-2 (sequential uncertainty fitting, ver. 2) method, the outputs of the calibrated model were u...

Abstract Evaluating Best Management Practices (BMPs) in watersheds using hydrologic and water quality models can help to establish an effective watershed management. Soil Water Assessment Tool (SWAT) was applied Big Sunflower River Watershed (BSRW) the Stovall Sherard (SSW) evaluate BMP’s impact at field scale respectively. SWAT calibrated validated for streamflow, sediment yield, total nitroge...

because of insufficient factors including facilities, budget, human resources as well as time watershed operation is not applicable throughout the basin. as a result, watershed operation should be performed in the sub-basins in which is more affectionate and the risk frequency of some events such as destruction, degradation; physical and financial damage and also flooding are considerably high....

This study tests the efficacy of using medium class land cover maps vs. the large class maps produced by the Korean Ministry of Environment for prediction of flow and CBOD, TN and TP concentrations. AVSWAT2000 was chosen as a model to process information for a sample site, Yongdam Lake watershed area, Korea. The watershed was divided into 11 sub-watersheds, as was done for implementation of the...
