Temporal and Spatial Trends of Precipitation and Mutation in Guangdong Province over the Past 60 Years by XU Chengyi

“…Based on the Mann-Kendall test,linear regression analysis,and sliding t-test,this study analyzes the daily precipitation data from 32 meteorological stations in Guangdong Province from 1960 to 2019.The results show that except for Guangzhou and Zengcheng in the Pearl River Delta region,which exhibit a significant increasing trend in annual precipitation,there is no significant increasing trend in annual precipitation in other regions of Guangdong Province.The spatial distribution of average annual precipitation shows that the Pearl River Delta and its adjacent areas are the areas with the highest precipitation,which decreases gradually towards the surrounding areas.In the analysis of annual precipitation mutations,eight meteorological stations are found to have different numbers of mutation points in different years.Among these,only the Pearl River Delta region shows an increasing mutation in annual precipitation in 1972.The research results can provide a reference for the management of water resources and flood prevention strategies in Guangdong Province to cope with climate change.…”

Ecological Flow Scheduling Solutions of Beijiang River by CHEN Yan, CHEN Xiang

“…Beijiang River is one of the four major river systems in the Pearl River Basin.The discharge of its control section Shijiao can represent the ecological flow of the Beijiang River.Additionally,it can also cooperate with the water regulation of Xijiang River during the saltwater intrusion in the Pearl River Delta and control the water volume of the Sixianjiao Section entering the delta,which is significant for the water security of Guangdong-Hong Kong-Macao Greater Bay Area.This paper first analyzes the current ecological flow of the control section of the Beijiang River.Then,the paper builds the reservoir group scheduling model according to the existing problems.Finally,it researches the ecological flow scheduling in the basin to propose an ecological flow scheduling scheme for the Beijiang River.…”

Construction and Verification of the Refined Forecast Model for Storm Surges Based on ADCIRC in Guangzhou by LUO Zhifeng, CHEN Gang, DAO Fuhai

“…Considering the joint influence of upstream water,astronomical tides,and storm surges,this paper constructs a refined forecast model for storm surges in Guangzhou based on ADCIRC.Driven by the Jelesnianski typhoon model,this model takes the upstream water and the forecast of tide levels in the open sea as the upper and lower boundary input and uses the irregularly triangular grids to simulate the topographic change of coastlines.The astronomical tides of six representative tide stations in cities near the Pearl River Estuary are compared with the measured water levels of six tide stations in Guangzhou under the influence of Typhoon Mangkhut and Hato for verification.The results show that the refinement degree of this forecast model can reach the hundred-meter level,and the maximum mean absolute error of astronomical tide fitting is less than 13 cm.The water increasing process,maximum water level value, and occurrence time of storm surges of the two typhoons are well fitted.All of these indicate that the model can basically reflect the astronomical tides and the water increasing process of storm surges along the Pearl River Estuary,which can provide a reference for the warning and high-resolution prediction of storm surges in Guangzhou.…”

Simulation on Water Diversion Regulation Effect in the Central Ditch of Hengqin New District,Zhuhai by LONG Xiaofei, WU Yaju, FAN Qunfang, ZHU Song, WANG Hua, ZHU Jinhe

“…The tidal river network area of the Pearl River Delta uses the ebb-and-flow differences between tidal level of the outer river and water level of the inland river to divert clear water for regulation.This is an effective way to improve the water environment of the tidal river network.The central ditch of Hengqin New District is in the tidal river network area of the Pearl River Delta.To improve the water environment of the central ditch in Hengqin New District,this study builds a one-dimensional hydrodynamic mathematical model of water quality and investigates the hydrodynamic regulation scheme for improving the regional water environment.Then,the water exchange effects of the original regulation scheme and the optimized regulation scheme are calculated and analyzed.The simulation results show that the optimized regulation scheme increases the regional flow rate by 0.20 m/s,shortens the half-exchange period by 101.5 h,and increases the water exchange rate by a factor of 1.1,which demonstrates a great improvement effect on the regional water environment.The results can be used as a reference for the implementation of the water diversion regulation scheme in the tidal river network area.…”
