Summary: This paper proposes an integrated model for urban flood modeling that accurately predicts the occurrence and impacts of urban flooding. By incorporating the Storm Water Management Model (SWMM) and the Dominant river tracing-Routing Integrated with VIC Environment (DRIVE) model, the integrated model successfully simulates urban rainfall-runoff and pipe drainage processes, while considering natural river basin runoff generation and routing processes. The validity of the integrated model is confirmed through three case studies in Haikou City, China.

Summary: In this study, a simulation-optimization model was used to find the optimal combination of LID controls for reducing urban stormwater runoff and pollutants. By linking SWMM to MOPSO, the model could identify potential solutions to achieve maximum reduction in peak runoff, TSS, and TN with minimum number of LID controls applications. The study found that peak runoff, TSS, and TN were reduced by 13%, 38%, and 24% respectively, and 25 LID controls were optimal for the BUNUS catchment area.

Summary: This study modeled the impacts of land use and land cover changes on runoff in urban wetland catchments. The results showed that the increase in impervious surfaces and decrease in pervious area led to an increase in runoff volume. To mitigate the negative impacts, the study suggested the distribution of rain gardens as a best management practice.

Summary: This paper presents a methodology to quantify the change in rainfall patterns and select the most feasible low-impact development (LID) design. Green roof and infiltration trenches showed better performance, and a combination of infiltration trenches, permeable pavement, and rooftop disconnection was found to be more efficient for extreme rainfall events. Implementing this feasible combination also provides the additional benefit of water recycle and reuse.

Summary: This article provides a global sensitivity analysis for the PP type of LID control in SWMM, aiming to support practitioners in calibration tasks by identifying the most influential parameters and those that can be neglected. The analysis focuses on flow volume and peak, while also exploring the influence of storm length and drain layer. Ultimately, it shows that fewer parameters can be focused on during calibration than initially expected.

Summary: This study evaluates the robustness of water quality modelling in sponge city construction using automatic calibration technique and field monitoring data. Results show that greenbelts and rain gardens perform the best, while barrels and green roofs are less robust. The modelling performance tends to be better under heavy rain and significant pollutant concentrations, indicating a potentially more stable and reliable design of infrastructures.

Summary: This study investigates the effects of LID systems in mountain regions using Lijia Mountain in Nanjing City, China as a case study. The author models and compares two LID systems schemes, namely segmental detention and retention, and terminal detention and retention, using SWMM software. The findings show that the terminal detention and retention scheme effectively delays peak flooding time and reduces peak discharge, while the segmental detention and retention scheme significantly reduces peak discharge.

Summary: This study evaluates the effectiveness of permeable pavements in mitigating urban runoff. Numerical simulations were used to investigate the runoff mitigation performance of different types of permeable pavements under rainfall events. The results show that porous asphalt, bounded at the bottom by an impermeable layer, is practically ineffective, while the other three types of permeable pavements demonstrate noticeable runoff mitigation effects. Additionally, the location of the permeable pavements in the study area has significant impacts on runoff.

Summary: This study presents a numerical appraisal of the performance of flexible, slit, and rigid barriers in mitigating natural geophysical mass flows. The study reveals that flexible barriers perform the best under runup mode, while existing analytical models may underestimate the peak impact for slit and rigid barriers and overestimate it for flexible barriers.

The numerical predictions show reasonable consistency with large-scale experiments. Systematic simulations are performed to examine the load-deflection mechanisms and quantify the load-deflection modes. The study improves understanding for practical design of flexible barriers in mitigating debris flows.

Summary: Urbanization has various impacts on river water quality, and understanding these impacts is crucial for effective river management. This study investigates the relationship between urbanization and two key pollutants in stream flows: nutrients and pathogens. Instead of using traditional economic or demographic metrics, our approach considers anthropogenic activities as indicators of urbanization and evaluates their effects on water quality parameters. The study also assesses the impact of urbanization on nutrient and pathogen trends in river waters in Hong Kong.

Summary: Nature-based solutions and similar natural water retention measures are commonly used by cities to manage urban runoff and improve sustainability. However, their performance is often not thoroughly assessed before construction or properly monitored and evaluated afterwards. This study investigates the field-scale performance of road runoff filters in managing stormwater quantity and quality. The results show that the filters effectively control runoff volume and shape, but the pollutant attenuation is relatively modest. The addition of biochar in the filter has no significant hydrological impact, but it does affect the effluent water quality.

Summary: Land drainage induces the oxidation of iron sulfide minerals, leading to acidification of fields and posing environmental hazards. This study developed a model to investigate the effects of mineral oxidation and cation exchange capacity (CEC) on soil water and drain discharge. The model was implemented and tested in an acid sulfate soil profile. Results showed that CEC played a crucial role in simulating pH profile, while oxidation of metastable iron sulfide minerals was faster than pyrite oxidation. The HP1 modeling platform facilitated the analysis of chemical transformations in response to drainage.

Summary: This study develops a two-dimensional hydrodynamic model framework that integrates hydrological and hydraulic processes for simulating urban floods, particularly in the presence of complex urban surfaces and subsurface drainage systems. By properly treating the bed source term and quantifying the drainage flow, the model is able to accurately predict urban surface inundation and flood hydrographs, as validated by five benchmark cases. The model framework has been successfully applied to simulate flood events in a rural-urban catchment, demonstrating its robust capability even in the absence of drainage information.

Summary: Urbanization and climate change will increase pressure on urban stormwater network. Accurate modeling of urban stormwater changes is necessary for predicting and mitigating the effects. This study uses climate models and a hydraulic Storm Water Management Model to analyze future seasonal changes in hydrological behavior. The results show notable changes in winter processes, with less snow days and increased flow events. There is also an increase in annual maximum hourly flow, particularly in winter. Monthly average runoff is predicted to increase during the cold period. Convection-permitting regional climate models provide added benefits throughout the year. Overall, there is a need to shift towards more advanced stormwater management strategies.

Summary: In this paper, the relationship between landslide properties and induced tsunami wave characteristics as well as the energy transfer between the landslide and waves was systematically investigated. A meshless smoothed particle hydrodynamics (SPH) framework was developed and validated for reproducing the complex processes of landslide-induced tsunami wave generation. Numerical simulations were conducted to study the effects of landslide deformability, relative initial positions, densities, landslide size, and downstream water depths on the maximum wave height. The results provide valuable insights into the understanding of landslide-induced tsunami waves and contribute to risk assessment and mitigation efforts.
