Actual Evapotranspiration Comparison in Hanjiang River and Weihe River Basin Based on Multiple Methods by LI Tongtong, LIU Dengfeng, MING Guanghui, HAN Songjun, MENG Xianmeng, HUANG Qiang

“…Accurate actual evapotranspiration assessment in a basin is important for revealing climate change trends and serving regional water resources management.The Hanjiang River and Weihe River are typical representatives of semi-humid and semi-arid watersheds on the north and south sides of the Qinling Mountains.This paper estimates and verifies the mean annual actual evapotranspiration of basins in the Hanjiang River and Weihe River basins by multiple methods including the water balance method, B2015 evapotranspiration complementary model, SWAT hydrological model, and evapotranspiration data products.The results show that the B2015 evapotranspiration complementary model is well applied to both study areas, and the calculated actual evapotranspiration error is less than 10%.The SWAT model performs well in the daily runoff simulation in both study areas, and the determination coefficient is larger than 0.63.The comparison results of multiple methods show that the annual actual evapotranspiration calculated by the water balance method and the SWAT model is closer to the actual value, and the calculated values of the B2015 evapotranspiration complementary model in Hanjiang River and Weihe River are 3.79% and 2.46% smaller than the actual values respectively.The actual evapotranspiration from the TEDAC and GLDAS evapotranspiration products is 31.08% and 36.54% larger in Hanjiang River and 13.72% and 5.06% larger in Weihe River, and the evaluation performance of the two products is better in the Weihe River than that in Hanjiang River.Additionally, it is still difficult to calculate the accurate actual evapotranspiration by current datasets and methods in specific basins.…”

Joint Operation of Reservoir Group in Longxi River Basin Considering Agricultural Water Demand by CHEN Si, XU Wei, ZHAO Siqi, YIN Shiming, YANG Yi

“…Water resources in small- and medium-sized basins are often not reasonably allocated,and the utilization rate of water resources is not high.In this paper,five reservoirs in the Longxi River Basin are taken as an example.Firstly,the hydrological model is constructed,and the parameters of the model are calibrated and verified by the 12-year measured runoff of Liujiantan Hydrological Station.The NSE can reach 0.89,the R² is 0.87,and the relative error (RE) is 5.4 %.The inflow process to the reservoir interval is obtained.Secondly,three representative crops of corn,rice,and sweet potato in the basin are selected to construct the reservoir irrigation water demand model.The crop coefficient method and Penman-Monteith formula are adopted to calculate the crop water demand and the USDA-SCS method was used to calculate the effective precipitation.Finally,the joint and single reservoir operation models of the Longxihe reservoir group to maximize the comprehensive water supply and power generation are built,and the POA solution and fuzzy analytic hierarchy process are utilized to optimize the scheme.The results show that the joint operation is more capable to balance the distribution of water resources between upstream and downstream reservoirs,improve the power generation efficiency and water supply guarantee rate,and reduce the amount of abandoned water than the single reservoir operation.…”

Study on Hydrological Prediction of Qingshui River Basin Based on PRECIS Regional Climate Model by MA Wenjing, PAN Zhangrong, LIU Zhenlu

“…Frequent occurrences of extreme weather will lead to unstable changes in rivers' hydrological conditions.The SWAT hydrological model is used to simulate and verify the runoff at the Quanyanshan hydrometric station in Qingshui River,and then the runoff change at the Quanyanshan station in the Qingshui River Basin by the middle and end of the 21st century is simulated based on the PRECIS regional climate model.The results show that by the middle and end of the 21st century,with the increase in temperature and the decrease in rainfall,the runoff volume of the Qingshui River will drop.Specifically,by the middle of the 21st century,the simulated runoff volumes are basically the same under two scenarios.However,by the end of the 21st century,the simulated runoff volume is larger than that under the SSP4.5 scenario due to the higher predicted rainfall under the SSP8.5 scenario.…”
