Assessing The Performance Of A Spatially Distributed Soil Erosion And Sediment Delivery Model For Han River Basin Of South Korea, Chung Gil Jung, Ji Wan Lee, So Ra Ahn, Seong Joon Kim Jul 2016

Assessing The Performance Of A Spatially Distributed Soil Erosion And Sediment Delivery Model For Han River Basin Of South Korea, Chung Gil Jung, Ji Wan Lee, So Ra Ahn, Seong Joon Kim

International Congress on Environmental Modelling and Software

When assessing the total sediment yield of a watershed through sediment transport from soil erosion process, the ratio of sediment delivery is a critical and uncertain factor during modelling. This study is to estimate watershed scale sediment yield with the evaluation of RUSLE (Revised Universal Soil Loss Equation) rain erosivity R factor for 15 years (2000 ~ 2014) using 1 minute data from 16 rainfall gauging stations in Han River basin (34,148 km2) of South Korea. The average R value in this study was evaluated as 4,708 MJ/ha mm/year with range of 1,652 ~ 10,143 ...


Hydrological Water Resources Assessment Of Cega-Eresma-Adaja Watershed System Using Swat Model, David A. Rivas, Angel De Miguel, Bárbara Willarts Jul 2016

Hydrological Water Resources Assessment Of Cega-Eresma-Adaja Watershed System Using Swat Model, David A. Rivas, Angel De Miguel, Bárbara Willarts

International Congress on Environmental Modelling and Software

In the hydrological assessment of water bodies, modeling is a key fact in water management strategies of watersheds and serves as a tool for decision making considering environmental issues as the core of sustainable development in the region. In this direction, SWAT model (Soil and Water Assessment Tool) was used to assess the water availability related with agricultural management in the watersheds of the tributary rivers Cega, Eresma and Adaja of Duero’s River in Spain both in the current and future climate change scenarios. To define the HRUs, land use maps from remote-sensing processes were used, extracting the agricultural ...


Improved Simulation Of Evapotranspiration For Land Use And Climate Change Impact Analysis At Catchment Scale, Ann Van Griensven, Samita Maharjan, Tadesse Alemayehu Jun 2014

Improved Simulation Of Evapotranspiration For Land Use And Climate Change Impact Analysis At Catchment Scale, Ann Van Griensven, Samita Maharjan, Tadesse Alemayehu

International Congress on Environmental Modelling and Software

Evapotranspiration is not only one of the major components of the hydrological cycle, it also controls impacts of drivers such as climate and land use changes. One of the widely used simulation tools for climate and impact studies is the Soil and Water Assessment Tool {SWAT). This study evaluates the evapotranspiration processes in SWAT in the Kenyan Mau forest within the Mara basin that drains to Lake Victoria. The study reveals that typical SWAT applications have flaws as in the implementation or parameterisation of tropical forests.

To improve the use of SWAT for land use and climate change studies, the ...
