Flood Mitigation Strategies: Integrating Hydrologic Engineering Systems- River Analysis Systems for Effective Management of Paremang Watershed

Jurnal Sylva Lestari
The Hydrologic Engineering System-River Analysis System (HEC-RAS) model is a model that can display water surface cross-sections in both 1D and 2D forms. That way, HEC-RAS can predict the amount of peak discharge that results in flooding. This study aims

Dam Break Simulation with HEC-RAS and OpenFOAM

, 2021
A dam break is a natural disaster that can cause significant property damage and loss of life. It's useful to identify potential flooding areas downstream in the event of a dam break. In this study both HEC-RAS and OpenFOAM are set up to simulate the inundation map downstream of the Dworshak dam in Idaho.

Diagnosing Post‐Wildfire Flood Governance Gaps Through a Values–Rules–Knowledge Lens: A Case Study From Kineta, Greece

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Post‐wildfire flash floods are an escalating climate‐driven hazard. Advanced technical modelling can now inform impact assessments and evaluate interventions to mitigate these risks, yet such analyses are often not supported by adequate governance frameworks to facilitate the implementation of the proposed solutions.

Development of integrated hydrologic and hydrodynamic models for flood modeling in Radiša catchment at Western Slovakia using HEC-HMS and HEC-RAS

Natural Hazards
Integrated hydrological and hydrodynamic models could help in understanding the dynamics of floods and developing effective strategies for flood management and mitigation to diminish the risk to people, communities, and the environment.

Flood Susceptibility Assessment through Statistical Models and HEC-RAS Analysis for Sustainable Management in Essaouira Province, Morocco

Géosciences, 2023
Floods are natural disasters that often impact communities living in low-lying areas in the northern and central parts of Morocco. In this study, our aim was to create a flood susceptibility map using three methods; the hierarchy process (AHP) frequency ...

Flow resistance parameterization for large wood in two‐dimensional depth‐averaged models: Effects of flow condition, blockage, and sediment

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Using 16 flume experiments and 2D modeling, we show that large‐wood flow resistance is not a fixed property of wood porosity but varies systematically with flow condition, blockage and most strongly sediment‐shaped bed topography. The drag coefficient and Manning's n are interchangeable, but calibration is essential where scour occurs.

Hydraulic reconstruction of catastrophic drainage from the Late Glacial, Lake Fraser, British Columbia, Canada

Journal of Quaternary Science, Volume 41, Issue 6, Page 873-887, August 2026.
ABSTRACT Glacial Lake Fraser, which formed in British Columbia against the retreating Cordilleran Ice Sheet, stored ~520 km3 of water before its near‐total drainage into the Salish Sea during an outburst flood event. Despite the impact of the outburst flood on sediment transport and landscape evolution in the Fraser River valley, its peak discharge and

Operation of Gate-Controlled Irrigation System Using HEC-RAS 2D for Spring Flood Hazard Reduction

De Computis, 2023
Flooding events have been negatively affecting the Republic of Kazakhstan, with higher occurrence in flat parts of the country during spring snowmelt in snow-fed rivers.
