Discussion on Prevention Measures and Remedy Options in Evaluation of Flood Control by DONG Hui

“…With China's economic and social development and expanding urban infrastructure construction,there are more and more construction projects within the scope of river channel management.The project construction usually occupies the flood discharge section,produces backwater,changes the local flow regime,and destroys the embankment section,affecting the safety of flood discharge and embankments.At the same time,floods scour the river channel and endanger the safety of the project.The evaluation of flood control should be carried out,and prevention measures and remedy options should be implemented simultaneously with the construction projects to reduce the influence of river-related projects on the river channel and ensure the flood control safety of the projects.This paper analyzes the river-crossing project and estuary mouth in terms of river-related concern,the key points of technical review,and the influence mechanism.Combined with project examples,the paper summarizes the prevention measures and remedy options in various evaluations of flood control according to their characteristics,including the layout method,scope of implementation,and design principle.It can provide a reference for the similar evaluation of flood control.…”

Analysis of Hydrodynamic Characteristics of Semi-Enclosed Harbors—a Cause Study of Xiangzhou Port by YANG Yugui, XUAN Xiaoming, LIU Guozhen, TONG Xiaolei, YUAN Fei

“…Affected by the construction of a series of projects,the semi-enclosed harbor often appears the phenomenon of weakening hydrodynamic force and worsening water exchange.In order to study the impact of project construction on the hydrodynamic environment of semi-closed harbors,a typical semi-enclosed port,namely Xiangzhou Fishing Port,in the Pearl River Estuary was taken as an example,and the impact of detailed control planning of the surrounding areas on flood discharge,tidal influx,and water exchange in Xiangzhou Fishing Port was studied.The results show that after the implementation of the planning scheme,the water level of the water area near the planning area and the upstream entrance gate,as well as the tidal volume of the tidal channel on the west side of Lingdingyang change slightly,but the tidal volume in the area of Xiangzhou Port decreases by about 1%.The hydrodynamic force is further weakened,and the semi-exchange cycle of the water body increases by about 3.2%.In particular,the water exchange capacity in the northwest corner of the port area is relatively poor,which is unfavorable to the water environment for a long time,and it is necessary to take hydrodynamic enhancement measures.The research results can provide a reference for hydrodynamic improvement in the water area of Xiangzhou Port.…”

Numerical Simulation of the Effect of Long-Term Reclamation on the Flow and Sediment Concentration in Binhai Port,Yancheng by ZHU Siyu, LU Dan

“…Binhai Port is located at the most obvious corrosive coastline of the abandoned Yellow River delta in the north of Jiangsu Province,where the near-shore wave and flow dynamic is strong,the sediment movement is relatively active,the underwater terrain is complex and the slope erosion is obvious.Based on the measured hydrological and sediment data and a two-dimensional mathematical model for wave,tidal current and sediment,this paper quantitatively analyzes the influence of the long-term reclamation project on the flow and sediment concentration in the study area and the surrounding estuary,and emphatically discusses the back silting characteristics and deposition causes of the 300 000-ton channel during normal and rough weather.The results show that:After the implementation of the reclamation project,the flow and sediment characteristics of the study area don't change in a large scale,and mainly the flow and sediment near the project site is affected.The sediment is deposited after the channel dredging and a sediment deposit centered at the area with peak sediment concentration is formed in the channel,with decreasing deposition thickness to the port and outer sea channel.During rough weather,the maximum deposition thickness can reach 8~24 times of that in normal weather,but it is less than 0.2 m/d and there is no sudden silting and navigation blocking.…”

The Impact of Breakwater Type on Hydrodynamic Environment in Semi-Closed Harbor by WU Qiong, LI Mugui, LUO Huan

“…Affected by breakwater construction,the water exchange of semi-closed harbor is often not smooth,and the self-purification ability is weak.To study the influence of different types of breakwater on the hydrodynamic environment in semi-closed harbor,the article took a typical semi-enclosed port in the Pearl River estuary,Xiangzhou fishing port as an example to analyze the differences of water exchange ability and the transport law of pollutants under the layout scheme of breakwater with opening width including 20、40、60、100 m.The results showed that,compared with the fully closed breakwater scheme,under the scheme of opening width of 20、40、60、100 m,the half exchange period of water in the harbor increased by 5.0 hours,11.0 hours,14.0 hours and 14.5 hours.The scheme with opening more than 40m was better than 20 m.However,there was no significant difference in the effect of the three schemes of opening 40、60、100 m.Considering the influence of regional pollution source input,under the scheme of breakwater opening,the concentration of inorganic nitrogen increased by 0.2~0.4 mg/L in the area near the opening.It further aggravated the pressure of inorganic nitrogen pollution in the northern part of the harbor,while the quality of water environment in the southern part of the harbor was improved due to the enhancement of water exchange ability.…”

Flood Disaster Control in Urban Watersheds Based on a Coupled Model-A Case Study of a Region in Guangzhou by ZHU Bifang, GAO Yanzhe, LAI Chengguang

“…Urban flood disasters have become one of the major disasters affecting urban development.Therefore,studying urban flood disasters is of great practical significance.Taking a region in Guangzhou as an example,this study constructs a coupled hydrodynamic model that comprehensively considers the rivers,the pipe network,and the surface under a holistic view of the watershed system to evaluate the effect before and after flood control measures.The results suggest the following conclusions:① The simulated risk points are basically consistent with those in the static flood risk map,indicating that the results of the constructed coupled model are reasonable.② Under the current conditions,the study area is exposed to a high flood risk in the case of a once-in-a-century rainstorm,and corresponding measures should therefore be taken urgently to mitigate the flood risk in this area.③ The implementation of reconstruction measures,such as pipe network reconstruction and pump station expansion,well alleviates the flood risk in the study area,indicating that the reconstruction scheme is reasonable.The reconstruction of the pump station at the Hengsha Chong Estuary effectively mitigates the waterlogging in downstream Hengsha Chong,which proves that approaching flood disaster control in the watershed from a holistic view of the watershed is more scientific and reasonable.…”
