Evaluation of Emergency Response Capacity of Urban Pluvial Flooding Public Service Based on Scenario Simulation

Abstract

The evaluation of emergency response capability under different pluvial flooding scenarios is an essential approach to improve the emergency response capability of flood disasters. A new evaluation method of emergency response capacity of urban public services is proposed based on urban pluvial flooding scenario simulation. Firstly, inundation area and depth under different pluvial flooding scenarios are simulated based on the SCS-CN model. Following that, space densities of all indicators include inundation area and depth, road network and the emergency public service institutions. Then, the indicator weight is determined by the combined weighting method of entropy weight and coefficient of variation. Finally, the emergency response capacity index (of each pixel) is calculated based on the graph stacking method. Taking Erqi District, Zhengzhou City as an example, the emergency response capacity of public service under different urban flooding scenarios is evaluated. The results show that the spatial distribution difference of public service emergency response capacity in Erqi District, Zhengzhou City is obvious, and with the increase of the precipitation return period, the high value area of public service emergency response capability decreases gradually and the low value area increases gradually. This method takes into account the specific urban flooding scenario and the layout of public service institutions and road networks that have strong practicability. the results of the evaluation can provide a reference for the construction of urban flood emergency response capacity and provide support for emergency decision-making.

A Study on the Accessibility of the Emergency Medical Services for Urban Kindergartens and Nursing Homes Based on Urban Pluvial Flooding Scenarios

“…At the same time, more medical resources should be allocated to the south and west of the Erqi District of Zhengzhou, especially the Wangzhuang community and Shuimo community, to achieve a balanced and fair distribution of medical resources. 3 Rational planning and construction of roads around medical institutions and densely populated areas to increase the density of the road networks, thereby improving road accessibility. 4 Medical institutions, kindergartens, and nursing homes located in low-lying areas with water accumulation should be relocated to reduce the risk of flooding.…”

“…In particular, the frequency and intensity of extreme precipitation events have shown a significant increasing trend, leading to an increased risk of urban pluvial flooding disasters [1,2]. In addition, with the continuous advancement of China's urbanization process, the urban population and social wealth continue to increase, problems related to urban pluvial flooding in cities are becoming more prominent, and the losses caused by urban pluvial flooding disasters are also increasing [3,4]. In recent years, serious urban pluvial flooding disasters have affected the service functions of urban traffic and caused significant casualties and economic losses in more than 62% of large-and medium-sized cities in China.…”

Mapping Tools for Flood Risk Rescue and Assistance Management

“…With a similar objective to the present research on rescue and assistance, there are studies by Sortino and Perles (2017) [46], Coles et al (2017) [47], Yin, Yu, and Liao (2021) [48], and Zhang et al (2022) [49]. These studies develop methods that combine flood modeling with network analysis to assess intra-urban accessibility by emergency services during flood events.…”

Scenario-Based Simulation Learning as a Tool of a Problem-Based Approach to Improving the Quality of Emergency Care in Ukraine

“…Сценарій-орієнтоване симуляційне навчання повинно бути широко імплементоване в освітній процес з підготовки та підвищення кваліфікації медичних кадрів і активно використовуватися під час викладання усіх клінічних дисциплін, насамперед з надання екстреної медичної допомоги. Такий підхід має стати невід'ємною частиною медичної освіти та безперервного професійного розвитку, оскільки дає здобувачам освіти можливість неодноразово практикувати й удосконалювати свою професійну компетентність без будь-яких ризиків для пацієнтів [6][7][8].…”
