Combined 1D and 2D Hydraulic Modeling within HEC-RAS

World Environmental and Water Resources Congress 2015, 2015
HEC has added the ability to perform two-dimensional (2D) hydrodynamic flow routing within the unsteady flow analysis portion of HEC-RAS. This new capability within HEC-RAS has the following attributes: 1. The ability to perform combined 1D and 2D modeling within the same unsteady flow model will allow users to work on larger river systems, utilizing ...

2D Hydrodynamic Analysis Using HEC-RAS in the way Sulan Watershed

Engineering Headway
During the period 1991 to 1995, floods in Indonesia caused trillions of rupiah in losses with 4,246 deaths, 6,635 injuries, around 7 million people suffering and 324,559 houses damaged (BNPB, 2013). In Lampung Province, there are 3 (three) River Basin Units (SWS), those are: Mesuji-Tulang Bawang SWS, Seputih-Sekampung SWS and Semangka SWS.

Identification of flood-prone areas using the HEC-RAS 2D model in a region of the Valley of Mexico

Chemosphere
This study aims to identify flood-prone areas in the Almoloya-Otzolotepec sub-basin, located in the Valley of Mexico, by applying HEC-RAS 2D model. The region, characterized by a semi-arid climate and variable topography, faces increased flood risks due to accelerated urbanization, which has significantly reduced agricultural land and expanded urban ...

A new approach for urban flood risk assessment using coupled SWMM–HEC-RAS-2D model

Journal of Environmental Management
Urban stormwater management is crucial for mitigating the impacts of flooding in urban areas, as it plays a vital role in protecting infrastructures, ensuring public safety, and preserving environmental quality. In this study, we develop a new method to quantify urban flood risk (UFR) by integrating the components of hazard magnitude and vulnerability.
