“…To sum up, a fast and effective emergency plan generation method plays an important role in supporting government emergency decision-making and command and improving emergency work efficiency. Building a unified emergency resource structure model is a basic link in the construction of an emergency resource system, such as the construction of an emergency resource input guarantee mechanism and the improvement of emergency resource guarantee and mobilization mechanism [ 11 ]. It is conducive to improving the support capacity of emergency rescue, realizing the effective integration and optimal allocation of emergency resources under the background of the urban comprehensive emergency platform and oriented by emergency demand, and realizing the agile response under the state of emergency rescue [ 12 ].…”

Due to the global climate anomaly, ecological environment damage, human activities, and other reasons, flood disaster has become a major threat to mankind. The emergency rescue resources under different subject management and different emergencies have different characteristics, attributes, and management modes, which restrict the unified dispatching, overall management, and efficient utilization of the comprehensive rescue command platform. The frequent occurrence of natural disasters can not only easily affect the public security of society but also pose a great threat to the safety of Chinese people’s lives and property. As the first-line person in charge of China’s response to natural disasters, local governments cannot deal with natural disasters well. More than thousands of people die from natural disasters in China every year. The economic losses caused amounted to hundreds of billions. The occurrence of various floods and natural disasters not only affects the local economic and social development but also relates to the production and life of the local people, and the stability of the local society and national unity. How to effectively deal with flood disaster is also an important index system to test the execution and management ability of the Party and the government. Therefore, it is necessary to deeply study flood disaster from the theoretical height, hoping to provide reference theoretical support and practical guidance for local county-level government flood disaster emergency management. At the beginning of the urban flood disaster, how to choose an appropriate response plan and implement it in time is an important way to effectively reduce disaster losses. Starting with the basic concept of flood disaster, this study studies and discusses the related theories of flood disaster emergency management, introduces the general situation of flood disaster emergency management, and analyzes the application of scenario construction technology in emergency management.

“…We believe it is an effective approach to apply emergy theory to disaster risk evaluation. In prior research, Wu utilized emergy to assess flood disaster risk in Zhengzhou [46]. Based on the outcomes from the integrated typhoon hazard index, Jiangsu Province appears as a significant demarcation, with the northern region bearing considerably less risk than its southern counterpart.…”

The evaluation of typhoon disaster risk is a widely discussed global topic. Currently, the index system method has become a common approach for the evaluation of typhoon disaster risk. However, the indices within the system are calculated independently, and subjective human factors significantly influence the assignment of index weights. The existing studies lack purely quantitative assessment methods, which makes the studies less precise and more difficult for other researchers to replicate. To bridge this gap, this study employs emergy analysis methods based on thermodynamics to develop a typhoon disaster risk evaluation index system for China’s coastal zone. Without the interference of weights and other human factors, the system contains various quantitative indices, including aggregate impelling energy, typhoon intensity emergy, adaptability emergy, the vulnerability index, and the integrated typhoon hazard index. Subsequently, these indices and socio-economic data were spatialized, and the evaluation of typhoon disaster risk was conducted at the city grid level in the coastal zone of China. The findings reveal that the high-risk areas for typhoon disasters in China are concentrated in prefecture-level cities along the southeast coast. The typhoon disaster risk index is higher in the southern region compared to the northern region, with a decreasing trend in the distribution of the integrated typhoon hazard index from coastal to inland areas. The aim of this study is to use a new quantitative evaluation method (emergy) to evaluate typhoon disasters. It also serves as a theoretical foundation and technical support for national and local governments in the formulation of policies for disaster prevention and reduction.

“…Flood hazard maps typically depict a range of flood‐related characteristics, including flood extent and depth, flow velocity, inundation duration, and sediment or pollutant load. Inundation maps provide plans for flood‐prone areas during rainfall events, enabling early warning and implementation of structural and structural measures to mitigate the risk (Mzava et al, 2021; Wu et al, 2020). For preparing flood hazard maps, it is needed to develop a hydrological model.…”

The rapid and frequent mapping of flood areas is crucial for monitoring and mitigating flood disasters. This study aimed to devise a flood inundation map for Nandigama City, located in the state of Andhra Pradesh, India. To analyze flood inundation, the HEC‐HMS hydrologic model was used to assess the effects of land‐use changes on runoff. The analysis of land use and land cover (LULC) revealed a significant increase in urban expansion around the study area over the last 30 years. The rise in urbanization and impervious surfaces has led to an 11.85% increase in the average peak discharge, from 4.39 m3/s in 2000 to 4.91 m3/s in 2020. These findings can provide significant insights for urban policymakers in the planning and management of flood control infrastructure in Nandigama.
