the modeling can provide a quantitative approach and consistency in the estimationsoil erosion and sediment yield by a wide range of conditions. in this study, the integration method of revised universal soil loss equation model, geographic information system and remote sensing techniques were used in order to identify the spatial distribution of soil erosion and sediment yield in the talar wat...

AgroEcoSystem-Watershed (AgES-W) is a modular, Java-based spatially distributed model which implements hydrologic/water quality (H/WQ) simulation components under the Object Modeling System (OMS3) environmental modeling framework. AgES-W has recently been enhanced with the addition of nitrogen (N) and sediment modeling components refactored from various agroecosystem models including SWAT, WEPP...

This paper examines the effect of raster cell size on hydrographic feature extraction and hydrological modeling using LiDAR derived DEMs. LiDAR datasets for three experimental watersheds were converted to DEMs at various cell sizes. Watershed boundaries and stream networks were delineated from each DEM and were compared to reference data. Hydrological simulations were conducted and the outputs ...

Significant advances in upland erosion modeling have been achieved in the past decade. The TREX (Two-dimensional Runoff, Erosion, and Export) watershed model has been developed at Colorado State University for the simulation of surface runoff from spatially and temporally distributed rainstorms on watersheds. The model has been applied in several countries with different climatic conditions. TR...

Geospatial databases built with geographic information systems served as primary sources of input data to the Agricultural NonPoint Source pollution model of watershed hydrology. Elevation, land cover, and soil data for four watersheds are the base from which we extracted the 22 input parameters required by the Agricultural NonPoint Source model. The study demonstrates the utility of employing ...

assessment of watershed management activities is one of the main subjects for future planning of practical projects and natural resources management. due to the lack of any tool for assessment of watershed processes in many cases, distributed hydrological models can be useful. the purpose of this study was evaluation of watershed management activities in kan watershed by hec-hms (hydrologic mod...

Abstract. The Taguibo River Watershed and Forest Reserve (TRWFR) is the primary source of water supply in Butuan City. However, intermittent became a problem for years now especially dry seasons. Hence, this study intended to assess impacts LULC change TRWFR by generating predict temporal land covers determine impact these current future watershed. This used Google Earth Engine (GEE) generate m...
