Pluvial flooding, driven by increasingly impervious surfaces and intense storm events, presents a growing challenge for urban areas worldwide. In Baltimore City, MD, USA, climate change, rapid urbanization, aging stormwater infrastructure are exacerbating flooding impacts, resulting in significant socio-economic consequences. This study evaluated the effectiveness of soil profile rehabilitation scenario using 2D hydrodynamic modeling approach Tiffany Run watershed, City. utilized different extreme high-resolution (1 m) LiDAR Digital Terrain Model (DTM), building footprints, hydrological data. These datasets were integrated into fully coupled model, City Catchment Analysis Tool (CityCAT), to simulate flood dynamics. The pre-soil simulation revealed maximum water depth 3.00 m most areas, with hydrologic groups C D, especially downstream area. post-soil was targeted at vacant lots public parcels, accounting 33.20% total area watershed. resulted reduced 2.50 m. Additionally, baseline runoff coefficient 0.49 decreased 0.47 following rehabilitation, model consistently recorded peak reduction rate 4.10 across varying rainfall intensities. validation contingency matrix demonstrated true-positive rates 0.75, 0.50, 0.64, 0 selected confirming model’s capability capturing real-world occurrences.

The overuse of concrete in historical areas, currently observed various urban watersheds Poland, may pose a significant threat to the water balance catchments, leading even pluvial flooding. distorted be, some extent, restored by sustainable green architecture designs. This paper presents an attempt at numerical assessment changes caused revitalization three main squares cities Lublin Voivodeship, Poland. A proposal for rain garden installation, allowing partial restoration balance, is also introduced. Numerical calculations runoff generation were performed SWMM 5 software real weather conditions recorded during period 1 June–31 August 2024. simulations show that increase imperviousness studied catchments results characteristics, with 78.2–90.9% volume and 108–141.7% peak flows. introduction proposed gardens allows reduction flows, down 18.1–30.2% 17.9–32.0%, respectively.

Abstract Every year, extreme rainfall events cause human deaths and economic losses around the world. Risk reduction strategies may involve implementation of structural measures that are widely extended financial relevant. Despite high reliance on these mitigation measures, there might occur instances overload, i.e. with intensities exceeding design value structures, have catastrophic consequences. In this framework, it is crucial to improve hydraulic works management, thus, we introduce a procedure at rain gauge scale for revising variables throughout their operational lifespan. This enables us enhance assessment probability failure works. Finally, investigate where experience overload during recording period, thus assessing occurrence rare yet possible events. To aim find most-suitable distribution describe daily maxima in Italy. Specifically, test performance four used bi-parametrical distributions different tail behaviour, by analysing an impressive dataset consisting 2282 gauges observations from 1860 2022. Our results show that: (1) 78% empirical samples exhibits heavy-tail behaviour; (2) when update applied, 64% shows higher-than-expected failure; (3) least one case associated 100-years return period recorded almost all regions. Based our results, existing designed safeguard populations activities face higher risk than initially expected.

Jagakarsa is one of the districts in South Jakarta that has a rainwater catchment area. Problems arise as result high rate population growth, which an impact on changes land use and increased surface runoff, causing flooding. On other hand, absence clean water provision facilities from government means people groundwater-drilled wells to meet their daily needs. Sustainable groundwater consumption subsidence vulnerability availability. Therefore, it necessary carry out research. This research seeks assess potential for harvesting based field observations. The was carried by analyzing rainfall data, surveys, program socialization, community socio-economic analysis.

Abstract. Flooding is an endemic global challenge with annual damages totalling billions of dollars. Impacts are felt most acutely in low- and middle-income countries, where rapid demographic change driving increased exposure. These areas also tend to lack high-precision hazard mapping data which better understand or manage risk. To address this information gap a number flood models have been developed recent years. However, there substantial uncertainty over the performance these products. Arguably important component model digital elevation (DEM), must represent terrain without surface artifacts such as forests buildings. Here we develop evaluate next generation hydrodynamic based on recently released FABDEM DEM. We compare it previous version using MERIT DEM at three study sites Central Highlands Vietnam two independent validation sets household survey remotely sensed observations flooding. The consistently outperformed MERIT, agreement between remote sensing was greater than sets.

Expanding urbanization has led to an increased risk of urban flooding, which poses a hazard humans. Scientific assessment flooding vulnerability (UFV) is essential protect human health and reduce losses. In this study, UFV was assessed using the Analytic Hierarchy Process-Press-State-Response (AHP-PSR) model in Jining City, China. The index (UFI) calculated from 13 indicators. Based on magnitude UFI, classified into five classes. Among them, areas very high, medium, low are 897.21 km2 (8.02%), 3192.14km2 (28.53%), 2063.22km2 (18.44%), 39773.96km2 (35.52%) 1060.47km2 (9.48%), respectively. Finally, suggestions were proposed for further management based results. results study can provide important reference government prevent mitigate flooding. Meanwhile, modeling framework be easily transferred other cities, providing new ideas assessment.
