Evaluation of Scheduling Schemes for Ecological Water Supplement of Rivers in Guangdong-Hong Kong-Macao Greater Bay Area Based on MIKE 11 by GAO Huayong, ZHAO Bikui, GUO Xiaojuan, TAN Chao

“…The results show that in the daily water supplement scheduling, if the estuarine sluice and ecological water supplement are not jointly scheduled, the water renewal efficiency of the Yachong River is low, and if they are jointly scheduled, the water quality is better improved when water is supplied for two hours per day in the first five days of the dry season, along with a lower electricity cost and the best comprehensive evaluation index. In the flood season with flood control and drainage scheduling, there is no need for ecological water supplement scheduling. …”

Spatial Dimension Analysis and Judgement of Abnormal Rainfalls by GAO Yueming, LIN Qinghua, LIU Shupiao, XU Chaoyang

“…The automatic reporting system of water levels and rainfalls is widely used in flood control,hydrology,and meteorology in China.The automatically measured rainfall data is one of the conditions triggering flood control early warning,and its quality and accuracy directly affect the credibility of the warning.In order to avoid false warnings,it is necessary to analyze and filter abnormal rainfalls in real time.This paper explored the correlation of rainfalls in spatial planes and compared the application effects of four statistical methods including the Pauta criterion,Chauvenet criterion,Grubbs test,and Dixon test in the spatial dimension,so as to infer whether the rainfall at a certain point is abnormal.Specifically,the Chauvenet criterion has the optimal comprehensive performance,and its accuracy,precision,recall rate,and F1 score are 0.86,0.78,0.83,and 0.80,respectively.In addition,the Grubbs test and Dixon test obtain similar results,but they both are slightly worse than the Chauvenet criterion since there may be many abnormal rainfalls in regional groups.The Pauta criterion has the worst performance,but its precision is the highest,which is 0.97.In addition,it is effective to optimize rainfalls that have been judged to be abnormal many times by algorithm flows,and the algorithm precision can be significantly improved.It has been proved that it is feasible to judge whether the rainfall at a certain point is abnormal from the spatial plane,which can effectively help water conservancy supervision departments to improve the quality of early warning and reduce labor costs.…”

Analysis of the Hydrological Regime in Small Basins within the Three Gorges Reservoir Area During the Impoundment Period by YIN Siwei, HU Huiling, WANG Yuefeng, LEI Chaogui

“…Hydrological regime is an important problem brought about by the Three Gorges Project and directly influences the development and utilization of water resources and ecological sustainable development in the Three Gorges Reservoir Area.Existing studies mainly focus on the influence of water storage on the main stream of the Yangtze River,with little attention to the runoff variations in small basins of the reservoir area.Based on the daily hydrological data of three typical small basins (Daning River,Pengxi River,and Modaoxi River) in this area from 2003 to 2017,by adopting the methods of trend analysis,runoff concentration degree, and runoff concentration period,the multi-time scale change characteristics of runoff are identified from the aspects of runoff and dispersion degree.Meanwhile,the runoff characteristics before and after 175 m water storage (2003—2008,2009—2017) are revealed,and the influencing factors of runoff variations are discussed.The results are as follows.① The average annual runoff of the Daning River Basin and Pengxi River Basin shows a downward trend,but there are no obvious variations in the Modaoxi River Basin.The monthly average runoff in the three basins varies greatly.The runoff of the Daning River Basin and Pengxi River Basin has a significant decrease in the flood season (July),while that of the Modaoxi River Basin has significant increases in the non-flood season (February),and the extreme value of runoff mainly shows a non-significant downward trend.② The runoff concentration degree and runoff concentration period of each basin show a non-significant decrease or increase respectively.③ After water storage,the runoff concentration period of each basin obviously lags behind the precipitation,the annual runoff distribution tended to be uniform,and the precipitation-runoff correlation decreases.The correlation coefficient of monthly average runoff decreases about 2%~6%,while that of annual extreme value decreases about 3%~12%.The research results can provide a scientific basis for hydrological and water resources management in small basins in the Three Gorges Reservoir Area.…”

Characteristics of Runoff Variation of Heishui River Basin in the Upper Reach of Minjiang River in Changing Environment by WANG Ning, WANG Wensheng, YU Siyi

“…This paper systematically analyzed the variation characteristics of runoff in the Heishui River Basin,the first tributary on the right bank upstream of Minjiang River,in a changing environment.The variation characteristics of runoff series were studied by using an improved heuristic segmentation algorithm,Mann-Kendall trend test,R/S analysis and wavelet analysis with the runoff data of Shaba hydrological station from 1960 to 2015.The results show the followings:① The abrupt change of annual runoff occurred in 1995.② The annual runoff showed a significant decrease trend with a decreasing rate of 0.32 m³/(s·a) in the past 56 years and may keep the decrease trend in the future.During 1960—1995,the annual runoff showed an insignificant decrease trend with a decreasing rate of 0.12 m³/(s·a),and the period of 1996—2015 witnessed an insignificant increase trend with an increasing rate of 0.80 m³/(s·a).③ Under the influence of environmental changes,the average annual runoff before the change point was larger than that after the point,whereas the inter-annual variation was smaller before the abrupt change.The intra-annual distribution form showed a double-peak curve before 1995 and a single-peak curve after 1995.The intra-annual variation range of runoff was significantly different before and after the change point,which could reduce flood control pressure in the basin but was not conducive to the utilization of water resources in non-flood seasons.④Annual runoff had multi-time-scale variation characteristics.During 1960—2015,the annual runoff had noticeable periods of 6 years,16 years and 28 years.Periods of 7 years and 16 years were found for 1960—1995 and 2 years and 5 years for 1996—2015.…”
