Flood Period Classification Forecast Based on Information Fusion and Recognition by XIE Zhigao, LIU Xia, WU Hengqing, LIU Jin

“…To solve the low simulation accuracy of flood forecast models caused by limited historical flood data in river basins,this paper employs the K-means clustering method to cluster typical floods by taking reservoir A as the research object.Meanwhile,it analyzes hydrological influencing factors such as rainfall intensity,rainfall center,and weather system,calculates various parameters of confluence models through a genetic optimization algorithm,and adopts a rough set method to explore the relationship between influencing factors and flood period confluence patterns.Finally,the flood period classification forecast based on information fusion and recognition is conducted.The results are as follows:① The absolute and relative errors of the four selected typical floods calculated by the classification forecast method are 9.01 m³/s and 2.95%,116.46 m³/s and 6.78%,30.92 m³/s and 17.55%,and 6.12 m³/s and 1.86% respectively;② The simulation accuracy of the flood classification forecast model built in this paper is higher than that of the traditional forecast methods,and the determination coefficients of different typical floods are all above 0.8.The results can provide references for the flood period classification and forecast in north China and other regions with less flood data.…”

Waterlogging Simulation and Drainage Countermeasures of Aotou Yuanpan Area in Daya Bay Based on MIKE URBAN by TAN Yuxin, WU Duanwei

“…Under the multiple impacts of urbanization,extreme rainstorms,and tidal level,the waterlogging situation in coastal cities is severe.To effectively assess the risk of waterlogging in coastal cities and propose targeted waterlogging prevention and control strategies,this study employs MIKE URBAN to analyze the drainage capacity of the pipe network and simulate urban waterlogging in Aotou Yuanpan of Daya Bay.The results show that the design frequency of 86% current pipe network is less than once a year,and the total waterlogged area is 631 824 m²,with the water retention time exceeding 24 h in Aotou Yuanpan.Therefore,the waterlogging is caused by the low drainage standards of the pipe network and the riverway.The waterlogged water can be directly discharged to Danao River by setting up a 32 m³/s pumping station and building new culverts on Zhongxing Central Road,Beiao Road,and Jingang Road in the independent Yuanpan catchment area.Meanwhile,the total waterlogged area can be reduced to 5 248 m²,and the water depth and retention time can be lowered to less than 0.15 m and 0 h respectively,thus effectively alleviating the waterlogging in Aotou Yuanpan.This study provides a solution for the reconstruction of drainage facilities and the prevention and control of waterlogging disasters in Aotou Old Town,which carries certain reference significance for engineering projects of the same type.…”

Research Progress and Prospect of Extreme Water Increase by Storm Surge in Estuaries — A Case Study of Guangdong-Hong Kong-Macao Greater Bay Area by LIU Yuexuan, LI Huijing, LI Lanbin, LIU Xiaojian

“…Significant increases in water and extreme tide levels caused by typhoon storm surges are the primary threat to flood safety in estuarine areas,and are also the main cause of major natural disaster losses in the Guangdong-Hong Kong-Macao Greater Bay Area in recent years.This paper reveals the evolution patterns of water increase in storm surges over the years and introduces corresponding research methods.Meanwhile,it systematically reviews research achievements on the formation mechanism of extreme tide levels in storm surges from both foreign and domestic perspectives.Combined calculation models of extreme tide levels formed by astronomical tides and storm surges in China and abroad are also summarized,with a focus on achievements in dynamic mechanisms during extreme water increase in storm surges.Additionally,a two-dimensional nested mathematical model of storm surges in the South China Sea and the Pearl River Estuary is built,and the most unfavorable typhoon intensity and path are designed.The maximum water increase distribution in the Guangdong-Hong Kong-Macao Greater Bay Area is preliminarily simulated and obtained.Finally,it is urgent to put forward a set of safe,concise,and applicable formula for calculating the extreme tide levels of storm surges as soon as possible based on the understanding of the physical mechanism of the interaction between astronomical tides and storm surges.…”

Analysis of No.1 Flood Disaster in Poyang Lake Basin in 2020 Based on Natural Disaster System Theory by LIAN Yuechen, GAO Lu, MA Miaomiao, WANG Lan, LIN Hui

“…China is one of the countries most hit by flood disasters in the world.Flood disasters have the highest frequency,are distributed in the widest scope,and cause the largest loss in China.It is of great guiding significance to analyze the characteristics of disaster system elements for a better understanding of the evolution process of flood disasters.This study collects the disaster-formative environment (topography and river network),disaster-bearing body (socioeconomy),disaster-inducing factor (daily rainfall),and disaster losses in the core area of the Poyang Lake Basin.Moreover,it investigates the disaster mechanism and evolution process of the No.1 flood disaster in the Poyang Lake Basin in 2020 and discusses the flood prevention and control measures for the Poyang Lake Basin.The results show that the high-intensity rainfall since June was the precondition of the No.1 flood disaster in 2020 in the Poyang Lake Basin,which led to almost saturated soil moisture.Under the joint action of extremely heavy rainfall from 1 to 8 July (strong disaster-inducing factor) and low elevation (high sensitivity of disaster-formative environment) in the core area of the Poyang Lake Basin,the floods spread quickly and flooded the socioeconomic system (disaster-bearing body) of the lake area in a short time.Case analyses of typical flood disasters from the perspective of disaster systems will help improve the capabilities for risk identification,disaster prevention,and disaster mitigation of regional flood disasters.…”

Evaluation and Forecast of Sustainable Utilization of Water Resources in Beijing by LI Congxin, XIANG Chunyu

“…Taking Beijing as the study area,this paper constructs an ecological footprint model and an ecological carrying capacity model of water resources in Beijing depending on the theory of ecological footprint of water resources.Further,it analyzes the changing trend and sustainability of water resources of the city.The grey prediction GM (1,1) model is used to predict the ecological footprint of per capita water resources in Beijing in the next three years.Reasonable suggestions are given according to the prediction results.The results indicate that the ecological footprint of water resources in Beijing shows a slow upward trend from 2000 to 2019,and the ecological footprint of water resources is much larger than the carrying capacity,which makes Beijing always in a state of ecological deficit.Moreover,the ecological pressure index of water resources is much greater than the critical value of 10,and the safety factor of water use is low.The ecological footprint of water resources of 10 000 yuan GDP presents a downward trend,indicating that the utilization rate of water resources in Beijing is increasing.The load index of water resources is quite large,which manifests that the potential for sustainable utilization of water resources is rather small and thus a large amount of water is needed to be transferred from other river basins.The forecast results show that the ecological footprint of per capita water resources in Beijing has a decreasing trend in the next three years.This is conducive to the sustainable development of water resources in Beijing and suggests that Beijing is in a good development trend.…”
