Enumerating the Effects of Climate Change on Water Resources Using GCM Scenarios at the Xin’anjiang Watershed, China

Abstract: The present study developed a novel approach to study the climate change impact on the water resources and generation of hydropower optimally using forecasted stream flows for the Xin’anjiang water shed in China. Future flows were projected using six large-scale Global circulation models (GCMs) with RCP4.5 and RCP8.5 scenarios. A newly developed mathematical modeling using particle swarm optimization was incorporated to work out the projected optimal electricity generation from the Xin’anjiang hydropower stati… Show more

“…The streamflow generated by using these datasets also shows uncertainties. In the prospect, as interpreted by [31], the projection of climatic parameters using CMIP5 GCM is considerably uncertain. In the present research, five GCMs of distinct variation in resolutions are used to predict future climatic scenarios.…”

“…The main objectives of SWAT model development are to simulate the quality and quantity of surface and groundwater and to predict the environmental impact of land use, land management practices, and climate change [56]. Previously, numerous researchers utilized the SWAT model for hydrological modeling studies in the various basin and sub-basin scales [29,31,45,[57][58][59][60][61]. The digital elevation model (DEM) is used for watershed delineation to investigate several properties of the basin, such as soil, slope, elevation, length of flow, streams created the longest path, etc.…”

“…The model integrates the state-of-the-art of remote sensing (RS), geographic information system (GIS), and digital elevation model (DEM) technologies and is able to simulate the water cycle with a high level of spatial detail. SWAT was widely applied on medium to large scale basins to assess the impact of management measure and climate change on hydrological processes, agricultural chemical yield, and sediment [42][43][44][45]. The water cycle simulated by SWAT is based on water balance equation which includes precipitation, surface runoff, lateral flow, actual evapotranspiration, percolation, baseflow, and change of soil water content [42].…”

“…Climate change can lead to changes in global hydrological processes, including melting glaciers, rising sea levels, and deterioration of the living environment [3]. The impact of climate change on water resources is mainly reflected in temperature and precipitation [4]. Precipitation is usually the most important source of water in a river, and it determines the amount of runoff [5].…”
