Flooding has become the natural disaster that causes the greatest losses, with urban flooding restricting the healthy development of cities. The ability to assess a city’s resilience to flooding is very important and would contribute to improving resilience and also help to inform planning and development. The aim of this study was to determine the key urban flood resilience indicators for three different Chinese cities (Wuhan, Nanjing, and Hefei) and to prioritize these for each city. A combined interpretive structure and network analysis method (ISM-ANP) model was used to evaluate and analyze the selected evaluation indicators. A four-level urban flood resilience evaluation network model was constructed to determine the interdependence between indicators and to calculate the priorities of the flood resilience indicators for the three cities. Overall, rescue capacity was found to be extremely important and was defined as the most important index. For Wuhan, indicators related to the distribution of waters were found to be more important, while for Nanjing, spatial planning and spatial structure of land use were found to be key priorities. In Hefei, the level of investment in infrastructure and the level of public resources occupy a more important position. The framework presented in this study contributes to the understanding of urban flood resilience and has the potential to be extended to other natural hazards.

Abstract. In the context of climate change and increasing urbanization, floods are considerably affecting urban areas. The concept of urban resilience may be an interesting means of responding to urban flood issues. The objective of this research is to propose a spatial decision support tool based on geovisualization techniques and a resilience assessment method. The goal is to localize the level of resilience modeled in different territories. The methodology proposed consists in integrating three resilience indicators applied to a case study in Avignon (Provence Alpes Côte d'Azur Region, France) and the use of geovisualization techniques: using GIS for data processing and analysis, visualization, mapping and model processing. The methodology integrates decision-making by identifying characteristics capable of improving urban resilience and facilitating its understanding using a visual tool. The results demonstrate the usefulness of modeling resilience using geovisualization techniques to identify the potential for local resilience, integrate local stakeholders into a process of clarifying the concept through the contribution of visualization, and consider easier access to this concept based on data analysis, processing and visualization through the design of maps.

Rainfall continues to increase due to the influence of global warming and is resulting in an increase in flood damage. The purpose of this study is to propose an approach for reducing urban flood damage and improving urban resilience. Urban flooding vulnerability analysis used land use and building characteristics as evaluation indicators. Disaster resilience analysis of urban planning facilities focused on urban and spatial aspects. The results of these analyses were overlapped to analyze whether urban planning facilities were properly located in areas vulnerable to urban flooding. The result of mapping the two results showed that there are some urban planning facilities with low resilience in the Red Zone, the central commercial area of Changwon, which has the highest vulnerability. This zone should have the appropriate placement of high-resilience facilities, such as disaster prevention facilities and space facilities. This study proposes a method to minimize flood damage in urban space. This system can cope with and systematically manage flood damage by increasing disaster resilience through appropriate land use planning and site selection for urban planning facilities.

Intense Storm

Urban drainage networks should be designed and operated preferably under open channel flow conditions without flux return, backwater, or overflows. In the case of extreme storm events, urban pluvial flooding is generated by the excess of surface runoff that could not be conveyed by pressurized sewer pipes, due to its limited capacity or, many times, due to the poor efficiency of surface drainage systems to collect uncontrolled overland flow. Generally, the hydraulic design of sewer systems is addressed more for underground networks, neglecting the surface drainage system, although inadequate inlet spacings and locations can cause dangerous flooding with relevant socio-economic impacts and the interruption of critical services and urban activities. Several experimental and numerical studies carried out at the Technical University of Catalonia (UPC) and other research institutions demonstrated that the hydraulic efficiency of inlets can be very low under critical conditions (e.g., high circulating overland flow on steep areas). In these cases, the hydraulic efficiency of conventional grated inlets and continuous transverse elements can be around 10–20%. Their hydraulic capacity, expressed in terms of discharge coefficients, shows the same criticism with values quite far from those that are usually used in several project practice phases. The grate clogging phenomenon and more intense storm events produced by climate change could further reduce the inlets’ performance. In this context, in order to improve the flood urban resilience of our cities, the relevance of the hydraulic behavior of surface drainage systems is clear.

Purpose In recent years, cities have been facing economic, social and environmental crises that need to be prevented and dealt with. The new subject that has been brought up to improve city resistance to crises is urban resilience. The purpose of this study is to compare the resilience of Tehran and Mashhad to identify the strengths and weaknesses of these two cities for better planning in critical situations. Design/methodology/approach The research methodology is a comparative survey. The importance of the subject was manifested through a literature review. A questionnaire is designed using “the Rockefeller Foundation and ARUP’s model” and the Delphi method for testing 21 research hypotheses to evaluate resilience in the two cities (12 Delphi questionnaires and 232 urban resilience questionnaires). The data is analyzed using independent samples t-test by SPSS software. Findings The results show that both the cities are weak in terms of resilience indicators and sub-indicators, but Mashhad is more resilient than Tehran. Originality/value This paper compares urban resilience in Iran for the first time through a comparative study between two metropolises in the country. The Delphi method also is used for the first time (in Iranian case studies) to obtain the dimensions of urban resilience. By comparing the two cities, we can better understand their strengths and weaknesses.

In the urban area, flooding becomes the most common disaster that has not been resolved until today. The utilization of river border area into housing and lack of absorption area becomes the trigger factor of urban flooding, as what is happening around Way Halim River on Seroja street. In this area, floods often happen during the rainy season, with the latest events recorded on January 21st, 2021. Analysis of flood intensities and discharges can be parameters for the decision-making of flood mitigation strategies. This study aims to analyze the flood discharges along Way Halim River, Seroja street by comparing the flood discharges resulting from three analysis methods of Synthetic Unit Hydrograph (SUH) including Gama I SUH, Nakayasu SUH, and Snyder SUH. Finally, suitable flood mitigation strategies were also proposed in this study based on the flood discharges and rain intensities. The results showed that Nakayasu SUH had the highest peak flood discharge than Snyder SUH and Gama I SUH. Based on the results of the investigation of land suitability; and analysis of rainfall intensities and flood discharges, the proposed flood mitigation in Seroja street is by installing biopore infiltration holes along Seroja street for storing water and reducing the risk of flooding in the area.

The concept of ‘resilience’ breaks down silos by providing a ‘conceptual umbrella’ under which different disciplines come together to tackle complex problems with more holistic interventions. Acknowledging the complexity of Davoudi’s approach (2012) means to recognize that ‘spatial resilience’ is influenced by many phenomena that are difficult to measure: the adaptation and transformation of a co-evolutive system. This paper introduces a pioneering approach that is propaedeutic to the spatial measure of urban resilience assuming that it is possible to define a system as being intrinsically vulnerable to stress and shocks and minimally resilient, as described by Folke in 2006. In this sense, vulnerability is counterpoised to resilience, even if they act simultaneously: the first includes the exposure to a specific hazard, whereas the second emerges from the characteristics of a complex socio-ecological and technical system. Here we present a Geographic Information System-based vulnerability matrix performed in ESRI ArcGIS 10.6 environment as an output of the spatial interaction between sensitivities, shocks, and linear pressures of the urban system. The vulnerability is the first step of measuring the resilience of the system by a semi-quantitative approach. The spatial interaction of these measures is useful to define the interventions essential to designing and building the adaptation of the built environment by planning governance. Results demonstrate how mapping resilience aids the spatial planning decision-making processes, indicating where and what interventions are necessary to adapt and transform the system.
