“…Another method to understand the effect of the rainfall events on the RBGE catchment is to consider the resilience and system performance, which varies from 0 (total loss of performance) to 1 (no loss). This work uses the measure suggested by Wang et al [37] where each grid square is defined as flooded or unflooded. System performance is defined as the ratio of the number of unflooded grid cells to the total number of grid cells and flood resilience is the aggregation of system performance over the entire simulation.…”

The main pond within the historic Royal Botanic Garden Edinburgh is an important component of urban blue-green infrastructure. This paper reports on flood resilience provided by the pond (simulated using the CityCAT hydrodynamic model), its water residence times (obtained using the Shetran hydrological model), and the ecology and biodiversity (vascular plants, bryophytes, aquatic invertebrates, phyto- and zooplankton, birds) of the pond and the adjacent area. The results show that the pond improves the flood resilience with at least a 27% reduction in the peak discharge during a 1 h, one in 100-year event. The area represents a biodiversity hot spot with a range of native taxa occurring among introduced plant species. The plankton community is dominated by diatoms, reflecting elevated levels of turbulence and a relatively short residence time, with an average value of 10 days. Analysis of macroinvertebrate community indicates a potential for water quality improvement. The results are discussed in relation to multiple societal benefits related to flood resilience, recreation, education, water quality, amenity and biodiversity value. The conclusions may prove particularly valuable for introducing practical measures in the water catchment, preventing waterlogging of the soil and ensuring an uninterrupted supply of public services. This article is part of the theme issue ‘Urban flood resilience'.

“…Numerous methodologies that are presented as a novelty are not found in the current practical activity, as there is no validation of them in real-case scenarios. Some national organizations do not have the technical and economic support to implement such methods in their current activity [129][130][131][132][133][134][135]. Research into the effectiveness of the methods presented in the published articles and their implementation in the current applications of the profile organizations should also be encouraged by giving the minimum requirements of IT infrastructure (hardware and software), professional training, and access to specialized databases.…”

Scientific papers present a wide range of methods of flood analysis and forecasting. Floods are a phenomenon with significant socio-economic implications, for which many researchers try to identify the most appropriate methodologies to analyze their temporal and spatial development. This research aims to create an overview of flood analysis and forecasting methods. The study is based on the need to select and group papers into well-defined methodological categories. The article provides an overview of recent developments in the analysis of flood methodologies and shows current research directions based on this overview. The study was performed taking into account the information included in the Web of Science Core Collection, which brought together 1326 articles. The research concludes with a discussion on the relevance, ease of application, and usefulness of the methodologies.

“…Essentially, resilience is a measure of system performance during or after a failure event, such as, can the system fail slowly, to what extend and magnitude the system can fail, how quickly and to what level can the system recover? There are various resilience measures for water distribution systems (Diao et al, 2016;EPA, 2015;Meng et al, 2018;Zhan et al, 2020), urban drainage systems (Mugume et al, 2015;Wang et al, 2019) and wastewater treatment plants (e.g., Juan-García et al, 2017;Meng et al, 2017;Sweetapple et al, 2017). All these measures aim to minimize the magnitude and duration of failure.…”

Urban Water Infrastructure (UWI) plays a central role in safeguarding water security and public health and welfare. Its main functions include abstracting, treating and delivering drinking water to communities and cities, collecting and treating wastewater to a standard before it can be safely discharged into a receiving water body, and collecting stormwater to prevent urban flooding. Traditionally, UWI consists of water supply systems, water distribution systems, water treatment works, urban drainage systems and wastewater treatment works; these systems were gradually built into a city and were generally designed, operated and managed in isolation without considering their interdependencies and wide impacts on the economy and society.Nowadays, the function of UWI goes far beyond providing water and wastewater services in cities. The potential value of blue green infrastructure, which is part of the UWI, is recognised in climate change adaptation, reduction of heat island impacts, improvement of biodiversity, and community amenity. UWI also plays a key role in reduction, reuse and recovery of resources through optimisation of the water-energy-materials nexus, helping embedding a circular economy in our society. In the era of big data and artificial intelligence, UWI digitalisation is an
