    Analysis of Variation Characteristics of the Annual Maximum Flood Flow of Main Streams in Guangdong Province by LIANG Yuanyuan

    Published 2022-01-01
    “…In order to understand the variation characteristics of the annual maximum flood flow at the main hydrological stations in Guangdong province and reduce the production,living,and ecological environment problems caused by floods,the annual maximum flood flow series from 1977 to 2014 at seven hydrological stations in Guangdong province,namely,Sanshui Station,Makou Station,Gaoyao Station,Shijiao Station,Boluo Station,Huazhou Station,and Chaoan Station,are studied.MK test and Pettitt test are used to carry out study or wavelet analysis on the characteristics of the trend,variability,and cycle changes of the annual maximum flood flow at typical stations in the main streams of Guangdong province.The results show that:① the annual maximum flood flow at Boluo Station and Chaoan Station decreases slightly,while that at the other five stations increases,with that at Shijiao Station and Sanshui Station rising significantly.② Four of the seven stations have variability,and they are Gaoyao Station (in 1991 and 1992),Shijiao Station (in 1992,2011,and 2012),Makou Station (in 1993),and Sanshui Station (in 1993),and the variability occurs more than once at Gaoyao and Shijiao stations.In terms of spatial and temporal distribution,the four stations with variability mostly belong to the Xijiang and Beijiang river systems in the 1980s,1990s,and the 21st century.③ Sanshui Station has two main cycles of 2~10 a and 20~30 a,and Makou Station has cycles of 2~9 a and 9~27 a.Gaoyao Station experiences a cycle of 4~10 a and 10~24 a,and Shijiao Station owns a cycle of 2~12 a and 12~20 a.Boluo Station has a cycle of 5~12 a and 12~24 a.In addition,Huazhou Station experiences three cycles of 3~7 a,7~18 a,and 18~26 a,and Chaoan Station experiences cycles of 3~10 a,10~14 a,and 14~23 a,respectively.…”

    Ecological Water Level Determination and Safeguard Measures for Rivers in Northern Jiangsu Plain by WANG Zhenqi, FANG Hongyuan, XU Guangdong, ZHU Ye, WANG Chengjie

    Published 2022-01-01
    “…Effective methods of calculating the threshold of river ecological flow (water level) need to be employed to obtain measures of controlling the ecological state of rivers in a plain river network and to build a robust long-term mechanism of ecological flow control.The Zongliutang River in the river network area of Northern Jiangsu Plain is divided into upper,middle,and lower reaches according to its objective environment and its actual operation and management situation.Then,the controlling condition of the ecological water level of each reach is analyzed respectively.Considering the hydrological characteristics,hydrodynamic characteristics,and observed hydrological data conditions of rivers in this river network area,several methods are utilized to calculate the ecological water level threshold of the middle reach of the river respectively.Those methods include the annual minimum water level method with a 90% guarantee rate,the wetted perimeter method,the minimum monthly average water level method,and the lowest survival water depth method.Through the comparative analysis of actual river operation and management schemes,the ecological water level targets of the upper,middle,and lower reaches of the river are comprehensively determined as 17.40 m,8.96 m,and 7.50 m respectively.After the control value of the ecological water level of the river is obtained by comprehensive analysis,the actual operation and management situation of the river is taken into account to propose specific safeguard measures for maintaining the ecological water level (flow) target of the river from multiple perspectives.Some of the measures are constructing a robust and feasible ecological flow control system,accelerating the construction of an information monitoring system of ecological flow and water intake and an early warning system safeguarding the ecological water level target,and strengthening the supervision and assessment of the implementation of river and lake ecological flows (water levels).…”

    Study on scour simulation and boundary condition conversion technology for a shallow foundation bridge by Gangping Fan, Huanzhe Li, Tianzhuo Wang, Jian Che, Xing Li, Chunyang Dou, Tong Wu

    Published 2025-02-01
    “…To prevent and mitigate scouring risks, this paper investigates the riverbed scouring characteristics of shallow foundation bridges under different hydrological conditions.The study found that under high water levels and flow velocities, scour depth significantly increased.Under extreme hydrological conditions, a horseshoe vortex forms at the base of the front end of the bridge pier, causing scour pits on both sides of the upstream face of the foundation, which is the main cause of foundation voids that first appear at 2580 s with a maximum scour depth of -2.51 m and a void area of 0.5%, continuing to increase over time.Based on simulated scouring data, this study proposes a method for converting boundary conditions from a scouring model to a mechanical model. …”
