Soil water content and streamflow were not significantly changed compared to the baseline scenario of existing land use. Land use change LUC involving different crop types or management can influence ecosystem level hydrological processes. The use of bioenergy crops for renewable energy generation can help to reduce reliance on fossil fuels and attain climate change objectives Chum et al. Temperate grasslands comprise a third of the utilized agricultural area across Europe and present a large potential area for the deployment of energy crops Eurostat, a. These traits could be of benefit in landscape flood mitigation schemes Environment Agency, ; Stephens et al. Resulting impacts of LUC to energy crops will be dependent on the extent of the area planted within river catchments and on regional climate, soil type, slope and altitude and stage of crop maturity Hastings et al. This is reflected in previous studies of the impacts of land use conversions involving grassland to Miscanthus and SRC.

Nago irrigation water. The increase in population causes the population to move to a higher area green zone. Batang Kuranji watershed has experienced a reduction in the area of forest land due to changes in land use activities by the population movement. As a result, land that was not watertight at first became watertight, the mainstay discharge or expected discharge is always available, always increasing during the rainy season and decreasing during the dry season. This study was conducted to determine the extent of land use change in the Batang Kuranji watershed, also to determine the main discharge that occurred in , , and using the Soil and Water Assessment Tool SWAT model.

Show all documents Sensitivity analysis of the Soil and Water Assessment Tools SWAT model in streamflow modeling in a rural river basin The uncertainties present in hydrological models have made them difficult and often impossible to apply. Four sensitivity analysis tests differing by the length of hydrological series, number of iteration and fluviometric station locations resulted in different sensitivity levels of input parameters used in the model. In this way, the present study emphasizes the need for a greater detailing of methodological processes used in the sensitivity analysis , so that different hierarchies of parameters can be obtained through the same tool. RBRH vol. In this context, hydrological models stand out as tools for several assessments. The results indicated that the SWAT model was eficient in simulating water low and sediment transport processes.

Wang, Y. In: Guido-Aldana, P. Under the influences of climate change and human activities, the water cycle under changing environment and distributed hydrological model based on physical mechanism have become the focus of hydrology research. The paper used CiteSpace to analyze the research progress based on previous literatures. The results of high frequency keywords and co-word analysis show that the research hotspots of SWAT model include water quality problem, sediment yield, model calibration, uncertainty analysis and sensitivity analysis. The literatures related to SWAT were divided into model application, model accuracy and model coupling.

SWAT was developed to predict the impact of land management practice on water, sediment and agricultural chemical yields in large complex watersheds with varying soils, land use and management conditions over long periods of time. It was designed to predict the impact of proposed or alternative land management practices on water, sediment and agricultural chemical yields within complex watersheds of varying soils, land use and management conditions over extended periods of time. The model operates on a daily time step, it is process based, computationally efficient, and capable of continuous simulation over long time periods. SWAT has the capability of incorporating a number of differing physical processes major model components in water shed modelling, these include;.
