Data Resolution and Model Complexity in Pluvial Flood Risk Assessment: Insights and Trade‐Offs

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT The increasing severity and frequency of urban pluvial floods has prompted numerous research studies on pluvial flood risk assessment. However, the literature reveals significant variability in the data resolutions and model types employed.

Modeling Bridges in HEC-RAS 2D: Comparison with Flume Experiments

Journal of Hydraulic Engineering
A set of experimental measurements with a physical model in a flume, measuring the head loss generated by different bridge geometries in steady and unsteady conditions, is used to test the performance of HEC-RAS 2D in modeling bridge hydraulics, a fundamental component of any flood study.

Building‐Scale Flood Hazard Modelling for Risk Assessment of Cultural Heritage

Journal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flooding is among the most frequent natural hazards threatening cultural heritage sites, yet current flood hazard studies often operate at urban or regional scales. While building‐scale damage models exist, they generally rely on flood depth inputs from large‐scale inundation models, inputs that may fail to capture the internal complexity of ...

An Integrated Modeling Framework for Sediment Dynamics During Urban Flooding: Application to Hurricane Harvey in Houston

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Floodwater can mobilize and redistribute large volumes of sediment from upland to downstream urban areas, threatening infrastructure, water quality, and ecosystem health. However, existing modeling approaches often fail to capture sediment dynamics in urban floodplains due to the lack of integration between upland hydrological processes and ...

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

Linking Remotely Sensed Hydromorphological Conditions With Biological Observations to Estimate Salmon Spawning Capacity

Ecohydrology, Volume 19, Issue 3, April/May 2026.
ABSTRACT Performing ecohydraulic assessments of salmon habitat is essential for planning and evaluating management actions. Current in situ and modelling approaches, although accurate, can be time‐consuming and expensive, which limits the areal extent of the study.

Hydrodynamic Modelling of Flexible Woody Vegetation With Delft3D FM: Implementing Physically‐Based 2D Flow–Vegetation Interaction Processes

Hydrological Processes, Volume 40, Issue 4, April 2026.
We developed and made accessible to end‐users a numerical 2D hydrodynamic modelling approach with several advantages: reliable applicability to flexible woody vegetation from emergent to submerged conditions, and improved estimates of effective bed shear stress for sediment transport. Novelties compared to existing numerical models include a physically

Integrating Modeled Flood Maps From the National Water Model and Diverse Sources for Enhanced Forecasting and Preparedness

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 2, April 2026.
ABSTRACT Flood mapping is critical for flood forecasting, preparedness, and risk management. In the United States, multiple federal agencies and organizations generate or archive flood inundation maps (FIM) using diverse models, data sources, and standards.
