Designing Resilient Urban Drainage And Floodplain Systems вђ Iris is developing novel techniques for analyzing and designing urban drainage and floodplain systems for increased resilience to extreme events, and how floodplain greenspace networks that improve water quality, increase biodiversity, moderate temperatures, cleanse air, and enhance human well being. The literature review highlights numerous quantitative studies that employ various methodological approaches, including urban resilience and hydrological modelling [21, 69], urban flood resilience and urban drainage systems [14, [70], [71], [72]], flood simulation and resilience [52, 73, 74] and mcdm, gis and flood resilience [58, [75], [76.
Designing Resilient Urban Drainage And Floodplain Systems вђ Reliability, resilience and sustainability are key goals of any urban drainage system. however, only a few studies have recently focused on measuring, operationalizing and comparing such concepts in a world of deep uncertainty. in this study, these key concepts are defined and quantified for a number of gray, green and hybrid strategies, aimed at improving the capacity issues of an existing. Urban drainage systems are designed so that they can accept runoff caused by design rain, i.e. rain of a certain duration and recurrence period (usually 1–5 years). design rain is determined by statistical analysis of historical rain events and does not consider changes caused by climate change recorded after the construction of the system. Rezende (2018) suggests that the search for resilience in the urban system requires the adoption of a continuous and retro fed process, adding values of adaptation and harmonization. in this discussion, we think that urban drainage system plays a crucial role, balancing the needs of the natural environment and the urban demands. This feasibility study demonstrates how utilising a multi objective optimisation approach to integrate the four pillars of suds design; water quality, water quantity, amenity and biodiversity (woods ballard et al., 2015), can, not only improve flood and water quality resilience, but also improve quality of life for the communities inhabiting.

Due to the inevitability of urban flood in presence of the rainfalls exceeding design capacity of urban drainage system, resilience approach has been recently considered instead of the conventional urban drainage management. however, acceptance of resilience approach necessitates considering sustainability in the selection of urban drainage projects due to the various aspect of flood impacts.
