As one of nature’s most destructive calamities, floods cause fatalities, property destruction, and infrastructure damage, affecting millions people worldwide. Due to its ability accurately anticipate successfully mitigate the effects floods, flood modeling is an important approach in control. This study provides a thorough summary modeling’s current condition, problems, probable future directions. The includes models based on hydrologic, hydraulic, numerical, rainfall–runoff, remote sensing GIS, artificial intelligence machine learning, multiple-criteria decision analysis. Additionally, it covers heuristic metaheuristic techniques employed evaluation examines advantages disadvantages various models, evaluates how well they are able predict course impacts floods. constraints data, unpredictable nature model, complexity model some difficulties that must overcome. In study’s conclusion, prospects for development advancement field discussed, including use advanced technologies integrated models. To improve risk management lessen society, report emphasizes necessity ongoing research modeling.

Quantitative flood hazard assessment methods: A review

Journal of Flood Risk Management, Год журнала: 2022, Номер 16(1)

Опубликована: Окт. 19, 2022

Abstract Flood hazard assessment is a fundamental step in flood risk mapping. Quantitative requires hydrodynamic modelling of the flooding process order to calculate spatial distribution suitable indicators representative intensity and frequency, hence its potential result harm. are usually defined by combining relevant parameters, mainly depth flow velocity, but also arrival time, duration, sediment or contamination load, so forth. A classification commonly introduced assign level areas potentially subject flooding. This article presents systematic review quantitative methods proposed scientific literature prescribed government authorities assess associated with natural anthropic listed compared specifying their underlying approach (heuristic, conceptual, empirical), exposed element which they were designed for (people, buildings, vehicles, etc.), fields application (river overflow, dam‐break, levee breach, debris flow). Perspectives future challenges analysis discussed. aims help modellers practitioners select most method case study interest.

A review of recent advances in urban flood research

Water Security, Год журнала: 2023, Номер 19, С. 100141 - 100141

Опубликована: Июль 13, 2023

Due to a changing climate and increased urbanization, an escalation of urban flooding occurrences its aftereffects are ever more dire. Notably, the frequency extreme storms is expected increase, as built environments impede absorption water, threat loss human life property damages exceeding billions dollars heightened. Hence, agencies organizations implementing novel modeling methods combat consequences. This review details concepts, impacts, causes flooding, along with associated endeavors. Moreover, this describes contemporary directions towards flood resolutions, including recent hydraulic-hydrologic models that use modern computing architecture trending applications artificial intelligence/machine learning techniques crowdsourced data. Ultimately, reference utility provided, scientists engineers given outline advances in research.

Toward Street‐Level Nowcasting of Flash Floods Impacts Based on HPC Hydrodynamic Modeling at the Watershed Scale and High‐Resolution Weather Radar Data

Water Resources Research, Год журнала: 2023, Номер 59(10)

Опубликована: Окт. 1, 2023

Abstract In our era, the rapid increase of parallel programming coupled with high‐performance computing (HPC) facilities allows for use two‐dimensional shallow water equation (2D‐SWE) algorithms simulating floods at “hydrological” catchment scale, rather than just “hydraulic” fluvial scale. This approach paves way development new operational systems focused on impact‐based flash‐floods nowcasting, wherein hydrodynamic simulations directly model spatial and temporal variability measured or predicted rainfall impacts even a street Specifically, main goal this research is to make step move toward implementation an effective flash flood nowcasting system in which timely accurate impact warnings are provided by including weather radar products HPC 2D‐SWEs modelling framework able integrate watershed hydrology, flow hydrodynamics, river urban flooding one model. The timing, location, intensity street‐level evolution some key elements risk (people, vehicles, infrastructures) also discussed considering both calibration issues role played resolution. All these analyzed having as starting point event hit Mandra town (Athens, Greece) 15 November 2017, highlighting feasibility accuracy overall providing insights field.
