Summary: Existing research on the impact of climate change on urban sanitation systems is limited and predominantly focuses on the effects on centralized sewerage systems in high-income contexts. Research on the impacts on nonsewered, complex, fragmented, and decentralized sanitation systems is lacking, as well as considering the interdependencies with other sectors and combinations of climate effects.

Summary: This study evaluated the capability of convolutional neural network (NNETC) and recurrent neural network (NNETR) models for flood hazard mapping in urban areas. The NNETC model showed slightly better prediction performance than the NNETR model, with terrain ruggedness index identified as the most important predictor.

Summary: Urban flood damage results in significant costs for private house owners, insurance companies, and water and wastewater utilities. This study analyzed 3113 damage claim cases over 30 years in the city of Malmo, Sweden, and identified the characteristics and causes of flood damage, highlighting the importance of sewer system types in flood damage claims. Furthermore, the study revealed an imbalance in claim counts between insurance companies and owners per event, emphasizing the need for further investigation and better planning to minimize flood damage.

Summary: This paper presents an integrated modeling framework for accurate predictions of flood hazard from heavy rainfalls. By integrating complementary models and utilizing GPU acceleration, the accuracy and simulation time of the model are improved. The framework is validated and tested in various scenarios, showing significant acceleration and the ability to simulate a large urban area in real-time.

Summary: This study employed the GIS-MCDA model, combining remote sensing, GIS, and analytical hierarchy technique, to identify flood-prone zones and determine the weights of various factors affecting flood risk in Chennai. The results indicated that regions close to rivers, with low elevation, slope, and high runoff density, were more susceptible to flooding. The flood susceptibility map generated by the GIS-MCDA accurately depicted the flood-prone regions in the study area.

Summary: This study calculated water losses in agricultural products due to flooding and created a flood risk map using GIS, highlighting elevation as a critical factor. Geographically weighted regression was also employed to evaluate the relationship between agricultural land use and flood risk, providing valuable insights for crop management and flood damage reduction for stakeholders and policymakers.

Summary: The main objective of this study is to develop a numerical model for the sewerage network of the central catchment area of Algiers. The model was evaluated and showed acceptable performance, indicating its potential application in other regions. This model can assist policymakers and managers in improving flood mitigation measures based on sewerage network predictions.

Summary: This article reviews the literature on urban flood modeling approaches and discusses hydrodynamic and microbial models for quantitative microbial risk assessment. The literature contains various hazards posed by urban flooding, but there are fewer examples of microbial risk from sewer system exceedance. So far, there is no perfect model or technique for quantitative microbial risk assessment from hydrodynamic simulations. The literature details many different methods, and we intend to detail the advantages and limitations of each method. The uncertainty in hydraulic data is a major issue in this research field, and any advancement in this discipline is likely to aid future research.

Summary: The blockages in gully systems increase the flood risk in urban areas. This study used a sophisticated hydraulic model to simulate water transportation and optimize cleaning strategies for different components of the gully system. The results showed that gully channels have the greatest impact on floodwater volume, but street inlets should be cleaned first for cost-effectiveness. Increasing cleaning frequency is more effective than increasing the budget to prevent a nonlinear increase in floodwater volume at high gully blockage ratios.

Summary: This paper demonstrates the use of numerical hydrologic and hydraulic modeling in quantifying flash flood risks, evaluating flood mitigation measures, and building operational warning systems for small urban communities. Case studies from Tegucigalpa, Honduras, and Istanbul, Turkey, showcase the application and transition of these models in real-world scenarios. Limited data and budget constraints are discussed, and feasible flood mitigation plans are recommended based on cost-to-performance analysis.

Summary: Urban flooding has become a significant disaster due to the inadequate flood control and drainage infrastructure to keep up with urbanization. This paper proposes a comprehensive methodology for urban flood risk assessment and management, which combines scenario simulation, risk assessment, and allocation optimization. The methodology is applied in the Xiaozhai area of Xi'an, China. By establishing an accurate coupled model of flooding, the current situation and design scenarios were simulated. Multi-factor flood risk levels were assessed based on the hazard-vulnerability framework, and an optimal scenario was obtained through NSGA-III. The results demonstrate accurate urban flood risk zoning and significant flood control effects.

Summary: In rapidly urbanizing developing countries, there is a distinct disparity between planned and informal urban development, with informal settlements often located in flood-prone areas. Managing flood risk in informal areas poses challenges and may exacerbate social inequality. Research indicates that reducing vulnerability of informal communities to flooding can help alleviate social inequality and promote sustainable economic growth.

Summary: Urban flood poses a serious threat to urban safety and sustainable development, necessitating the understanding of potential changes for risk mitigation. Existing studies have mainly focused on physical characteristics and post-disaster reconstruction, while neglecting the potential risk consequences of flood risk propagation.

Summary: This study examined the applicability of the SFD method in combination with ADVM data at the Sejong-weir on the Geum River in Korea. The experiment found that the SFD rating curve developed using ADVM data showed higher agreement with measured data in terms of hydrograph reconstruction, compared to the conventional simple rating curve, and that uncertainties were higher at lower flow rates for all rating curves.
