HU Dongdong;LIU Junguo;ZHANG Xiaolei;JU Junyan;LI Zhengyang;【Objective】 This study aims to establish an urban flood simulation system applicable to the ″7·20″ extreme rainstorm event, accurately reproduce the flood evolution process, and reveal the formation mechanism and key influencing factors of urban waterlogging, so as to provide a scientific basis for the optimization of urban flood control and drainage and the response to extreme rainstorms. 【Methods】 Based on the basic data of river channel distribution, topographic elevation, and drainage pipe network layout in Zhengdong New District, a three-dimensional coupled urban flood model of ″river channel-surface-drainage pipe network″ was constructed on the MIKE FLOOD platform. The reliability of the model was improved through calibration and validation, and the inundation characteristics and waterlogging causes of the study area under extreme rainstorm conditions were systematically analyzed. 【Results】(1) During the rainstorm, the Jialu River section in Zhengdong New District experienced inflow exceeding the design standard, with a significant risk of dike overtopping, and river overflow further aggravated waterlogging in the surrounding areas.(2) The surface inundation in the study area was characterized by a wide range, large water depth, and long duration, and the inundation risk was prominent in the core areas.(3) At the peak rainfall period, 91.56% of the drainage pipes in the entire district were in overloaded operation, and the drainage capacity was significantly restricted due to the backwater effect of the high river water level.(4) The combination of drainage system overload, river backwater, and dike overtopping risk was the main cause of severe waterlogging, and insufficient coordination between natural water systems and artificial drainage systems further amplified the disaster impact. 【Conclusions】 Under the ″7·20″ extreme rainstorm, the waterlogging in Zhengdong New District is jointly triggered by extreme rainfall, drainage network overload, and insufficient system coordination, among which the insufficient carrying capacity of drainage pipe networks and the low flood control standard of river channels are the key shortcomings. In the future, it is necessary to raise the flood control standard of river channels, strengthen coordinated scheduling between drainage systems and natural water systems, optimize the layout of drainage facilities in flood-prone areas, and improve the comprehensive urban flood control and drainage system.
Assessment of Harmonious Prevention and Control of Water Disasters Oriented to Harmonious Coexistence of Human and Nature
ZUO Qiting;YANG Zhikai;YAN Changwei;【Objective】 The scientific identification and improvement of deficiencies in regional harmonious water disaster prevention and control are vital for achieving harmonious coexistence between human and nature. 【Methods】This study, based on the concept of harmonious coexistence between human and nature, elucidated the definition and connotation of harmonious prevention and control of water disasters. Four discriminant criteria were proposed: controllable disaster risk, ecosystem health, stable disaster-bearing resilience, and prevention and control carrying capacity. An assessment system for harmonious prevention and control of water disasters was constructed, comprising modules such as evaluation indicators, evaluation methods, and factor identification. On this basis, the SMI-P comprehensive evaluation method was employed to quantify the water disaster harmonious prevention and control index(WPI). Methods such as the standardized precipitation evapotranspiration index(SPEI), run theory, and the InVEST model were used to quantify the evaluation indicators, while obstacle degree analysis was applied to identify the influence degree of each indicator. A case study was conducted in Henan Province with regional zoning. 【Results】(1) From 2008 to 2023, the WPI of 18 prefecture-level cities in Henan Province showed an overall steady upward trend, with Jiaozuo City exhibiting the highest multi-year average WPI(WPI = 0.640).(2) During the study period, significant spatial disparities in WPI were observed, with western and northern Henan outperforming eastern and southern regions, while central Henan lagged behind in harmonious prevention and control of water disasters.(3) The proportion of investment in water conservancy facilities was the primary obstacle factor affecting WPI, and ecosystem health was the key criterion driving WPI changes. 【Conclusions】 The constructed assessment system for harmonious water disaster prevention and control can effectively quantify and evaluate regional water disaster prevention and control levels, revealing its spatiotemporal evolution patterns and core constraints, with theoretical rationality and practical operability. The research findings can provide data support and decision-making references for water disaster prevention and control in Henan Province′s prefecture-level cities.
Water Security Evaluation in Beijing Based on Gini Coefficient and Set Pair Analysis
MEN Baohui;WU Xingtao;PANG Jinfeng;LIU Nan;【Objective】 Water security is the foundation of socioeconomic development and a guarantee for human production and life. Conducting in-depth research on the water security situation in Beijing, in order to provide quantitative reference for the optimization and spatial allocation of urban water resources. 【Method】 This study constructed a water security evaluation indicator system for Beijing based on the DPSIR model, used the Gini coefficient to evaluate the overall water security situation in Beijing and to identify the strength of the influence of each indicator, and conducted a comprehensive evaluation of the water security situation of each administrative district in Beijing from 2018 to 2022 based on the set pair analysis method. 【Results】(1) The water security situation of each administrative district in Beijing was 9.09% at level II(relatively safe), 65.45% at level III(basically safe), and 25.45% at level IV(relatively unsafe).(2) Among the two sets of matching relationships, when the water security situation with per capita GDP was the matching object, the multi-year average value was level IV(relatively unsafe), while the water security situation with population size as the matching object was worse, with the multi-year average value being level V(extremely unsafe).(3) The water security situation in Beijing was the best in 2020 and 2021, and the worst in 2022. 【Conclusions】 Regarding the water security situation in Beijing, it is recommended to adjust the spatial layout of Beijing′s water resources, improve the industrial development structure, disperse the dense population concentration, reduce fertilizer application rate, implement soil and water conservation projects, promote water-saving irrigation technology, and strengthen the efforts in controlling soil erosion.
Analysis of Spatiotemporal Variation Characteristics of Groundwater Level and Impact of Climatic Factors in Poyang Lake Basin
YANG Mei;HU Mei;LI Yunliang;XING Zikang;SONG Gang;WU Guangdong;CHEN Jing;CHU Xiaodong;【Objective】 This study aims to reveal the spatiotemporal evolution patterns of groundwater level in the Poyang Lake Basin and the response mechanisms to extreme drought events, thereby providing a theoretical basis and decision-making references for sustainable water resource management and ecological conservation under climate change. 【Methods】 Based on data from 116 groundwater observation wells from 2018 to 2022, this study analyzed the spatiotemporal changes in groundwater level and used a geographically weighted regression model to explore the effects of precipitation, evapotranspiration, and surface water distribution on groundwater level dynamics. 【Results】(1) In over 90% of the Poyang Lake Basin, groundwater depth was within 9 m, and in over 50% it was between 4 and 8 m, with greater depth in autumn and winter.(2) Influenced by topography and geomorphology, the groundwater level in the upstream of the river basin reached 200-300 m, while that in the downstream was approximately 20 m. Groundwater generally flowed from mountainous areas to the near-lake plain areas, and the groundwater level dynamics in plain areas showed greater variability.(3) Multi-factor analysis showed that compared to evapotranspiration(contribution <1), surface water distribution and precipitation had a stronger impact on groundwater level fluctuations(contribution>2).(4) The impact of extreme drought in 2022 on groundwater level mainly occurred after July, manifesting as an increase in groundwater depth and a decrease in storage. 【Conclusions】 Groundwater level in the Poyang Lake Basin is highly sensitive to precipitation changes, and surface water dynamics and precipitation processes are the main driving factors of groundwater level changes. This study can provide a scientific basis for water resource management and ecologically sustainable development in the river basin.
Comprehensive Evaluation of Water Security Patterns in Mountainous Cities and Towns Based on Multiple Objectives
LUAN Chunfeng;WANG Yingzhuo;ZHAO Renjing;ZHANG Yi;【Objective】 This study conducts a comprehensive evaluation of water security and spatial pattern analysis, identifies the key factors affecting water security and improves the operability of formulating spatial strategies for water security in mountainous towns. 【Methods】 Taking Jiyuan City as a case study, a multi-objective framework addressing water resources, water environment, water ecology security, and water hazard mitigation was established to develop an integrated evaluation indicator system for water security patterns. Utilizing geographic information systems(GIS) and remote sensing(RS) spatial analysis techniques, the study areas were classified into high, moderate, and low security levels. Single-element security patterns were subsequently overlaid to derive the comprehensive water security pattern. 【Results】(1) The water resource security pattern of mountainous towns was mainly affected by anthropogenic factors, and urban areas were at an extremely low security level.(2) The water environment security pattern was mainly affected by factors such as surface water quality and water purification capacity, with pollution sources being the key influencing factor.(3) The water ecological security pattern was mainly affected by soil and water conservation and water conservation capacity. The key factors determining soil and water conservation capacity were topography, land use type, and vegetation coverage, while water conservation capacity was strongly influenced by precipitation and land use type.(4) The water disaster avoidance security pattern was mainly affected by the scope of rain-flood inundation, which was closely related to rainfall, land use type, topography, and other factors.(5) The comprehensive water security pattern of mountainous towns was closely related to such elements as topography, land use type, and rivers. 【Conclusions】 The evaluation indicator system of water security pattern under the guidance of multiple objectives expands the depth and breadth of evaluation, enables a refined identification of the action intensity of various influencing factors and their spatial relationships, and provides theoretical support for addressing water security issues in mountainous towns in China.
