Impacts of retention basins on downstream flood peak attenuation in the Odaw river basin, Ghana

Journal of Hydrology: Regional Studies, 2023
Study region: Odaw River Basin (ORB) in Ghana Study focus: We simulated and examined the impacts of retention basin as a hydraulic structure in attenuating the flood peaks downstream of the ORB with a coupled HEC-HMS and HEC-RAS models for different ...

Towards Coupling of 1D and 2D Models for Flood Simulation—A Case Study of Nilwala River Basin, Sri Lanka

Hydrology, 2022
The Nilwala river basin is prone to frequent flooding during the southwest monsoon and second intermonsoon periods. Several studies have recommended coupling 1D and 2D models for flood modelling as they provide sufficient descriptive information of ...

Effects of DEM source and resolution on the HEC-HMS hydrological simulation

Shui kexue jinzhan, 2015
Hydrological simulations are affected by the parameters derived from DEM,which describes the watershed features. Xitiaoxi River basin was selected to simulate two runoff processes in Jun and Aug to Sep 2011 using the HEC-HMS model with ASTER 30 m DEM ...

On the Clark Unit Hydrograph Model of HEC-HMS

Periodica Polytechnica Civil Engineering, 2017
A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.

Hydrological modelling of wadi Ressoul watershed, Algeria, by HEC-HMS model

Journal of Water and Land Development, 2016
AbstractThis study presents a flood estimation model for wadi Ressoul in El Berda watershed, north east of Algeria. To ensure the overall consistency of simulated results, it is necessary to develop a validation process, particularly in regions where data are scarce or limited and unreliable.

Analysis of flood events in the Three Gorges Reservoir Region using the coupled VIC‐CaMaFlood hydrological model

River, EarlyView.
Abstract In recent years, the Three Gorges Reservoir Region (TGRR) has been increasingly affected by climate change, with frequent flood events posing challenges to regional flood control. The NO.1 flood of the Daning River in 2024 further highlights the severity of flood risks in the region.

Integrated hydrologic and hydrodynamic modeling for flood hazard assessment in Ajay River Basin, West Bengal, India

River, EarlyView.
Abstract The Ajay River, originating from the Chotanagpur Plateau (Bihar) and flowing through Jharkhand into West Bengal before merging with the Bhagirathi‐Hugli near Katwa, is among the most flood‐prone rivers in the region. Its lower reaches frequently experience rainfall‐induced flooding and embankment breaches during the mid‐ to late‐monsoon season.
