Temperature Modeling with HEC - RAS

Critical Transitions in Water and Environmental Resources Management, 2004
The Hydrologic Engineering Center – River Analysis System (HEC - RAS) is a onedimensional unsteady flow hydraulics program capable of simulating a full network of open channels and hydraulic structures such as bridges, culverts, and weirs, with variable spatial discretization. HEC - RAS is widely used, is in the public domain, and has been applied to a

Sediment Transport Modeling in HEC RAS

Impacts of Global Climate Change, 2005
Sediment transport capabilities have been added to the Hydrologic Engineering Center's River Analysis System program (HEC-RAS). HEC RAS can perform mobile bed sediment routing computations with quasi steady (histogram) flow series data. For each flow in the time series a water surface profile is calculated.

Hydraulic Modeling beyond HEC-RAS

Impacts of Global Climate Change, 2005
A drainage swale hydraulic analysis was conducted by WEST Consultants, Inc. as part of a dispute regarding a proposed subdivision. The primary purpose of the study was to evaluate the adequacy of the proposed drainage improvements. The downstream portion of the flow system consisted of: a steep triangular channel discharging into a debris basin, a ...

Common Modeling Mistakes Using HEC-RAS

World Environmental and Water Resources Congress 2007, 2007
The U.S. Army Corps of Engineers River Analysis System (HEC-RAS), developed by the Hydrologic Engineering Center, has long been the standard for one- dimensional hydraulic modeling. Despite the wide spread use of the program, even seasoned engineers can fall victim to some common modeling mistakes using HEC-RAS.

Advanced Guidance on Use of Steady HEC-RAS

World Environmental and Water Resources Congress 2008, 2008
HEC-RAS is a one-dimensional steady or unsteady open channel flow model developed by the U.S. Army Corps Engineers' Hydrologic Engineering Center. It is probably the most widely used one-dimensional program in the world, and is used for a variety of applications, such as flood insurance and flood reduction studies, bridge hydraulics, stream restoration,

Dam and Levee Breaching with HEC-RAS

World Water & Environmental Resources Congress 2003, 2003
With the release of HEC-RAS 3.1 (November, 2002), users can now perform dam and levee breaching analyses. This paper discusses the methodology used to perform the breaching, as well as the available options. The data required to perform such an analysis is reviewed, and available output from the model is displayed.
