Dams play a vital role in supporting agricultural productivity, water supply and flood control in Indonesia. However, their structural failure poses serious threats to human safety and regional development. This study integrates hydrological and hydraulic modelling as part of a comprehensive disaster risk mitigation strategy, focusing on the Keureuto Dam in North Aceh, Indonesia. The dam, a 74-m-high earthfill structure with a total storage capacity of 215.94 million m3, presents significant downstream flood risk in the event of structural collapse disaster risk mitigation. Using the HEC-RAS 5.0.7 model, a dam breach scenario was simulated under overtopping conditions based on Froehlich’s empirical equations. The simulation results revealed a maximum flood depth of 19.577 m, a peak flow velocity of 1.387 m/s and an inundation area of approximately 49.91 km2 affecting 84 villages across four sub-districts. Contribution Beyond quantifying flood characteristics, this study emphasises a decision-support tool for disaster preparedness, enabling hazard mapping, evacuation planning and the development of early warning systems.
Flood hazard maps are a basic instrument of disaster risk management, yet their preparation normally assumes that streamflow, water level and inundation records are available for model calibration. This study therefore aims to establish a flood hazard mapping framework for data-scarce basins, and to examine how far the...

This study investigates the potential flood impacts of a possible failure of the Gödet Dam located in Karaman, Türkiye. Floods resulting from sudden dam failures can spread rapidly, causing significant loss of life and property. In this research, the Hydrologic Engineering Center’s River Analysis System (HEC-RAS) and t...

Timely flood hazard assessment is essential for determining flood risk levels and plays a critical role in flood prevention and mitigation, particularly in extreme rainfall events under global climate change. This study developed a flood risk model (FRM) incorporating sediment deposition as a key factor to address a ga...

Failure of a dam can release a large volume of stored water suddenly and endanger the population and property
downstream. This study presents a two-dimensional dam break analysis and flood inundation mapping of the Polavaram Dam, a
multipurpose project on the Godavari River in Eluru District, Andhra Pradesh, India, usi...

Flood control systems are experiencing increasing pressure and growing threats from the impacts of climate change and urbanization. Nature-based solutions (NbS) provide flood-risk mitigation and ancillary benefits, but their quantitative effectiveness remains inadequately evaluated. This paper aims to provide quantifie...

Rapid urbanization in Malang City, East Java, has increased flood exposure along the Bareng River, where dense riparian settlements restrict channel conveyance. This study integrates hydrological–hydraulic modeling and spatial exposure assessment to support flood-hazard-based spatial planning. Design rainfall (2–100-ye...
