HEC-RAS's finite volume solver involves tightly coupled computational fluid dynamics (CFD) calculations. These calculations are highly interdependent – data from each simulated cell needs to ...

For those of us working with HEC-RAS, it's easy to fall into the trap of thinking that sheer core count equals superior performance. However, when it comes to tightly coupled fluid dynamics modeling, ...

ABSTRACT: Dams offer numerous benefits to society, but their failure can lead to catastrophic floods, causing severe damage to both people and property. Simulating dam break events and subsequent ...

This paper presents the impact of the choice of building representation techniques and hydrodynamic models on urban flood simulations using HEC-RAS 2-D for the Toce River physical model. To this end, ...

ABSTRACT: Flooding poses significant risks to communities in wetlands and densely urbanized regions, necessitating robust prevention strategies. This study focuses on the Canche and Liane watersheds ...
