Sensitivity Analysis of Parameters in HEC-RAS Software

Applied Mechanics and Materials, 2014
As for the level of tail-water often rose when the situation of tailrace river changing during the process of construction of hydroelectric power station, one-dimensional mathematical model is used through two procedures to solve this problem. In the first, the sensitivity of three key parameters including roughness, cross-section spacing Δs, starting ...

The Ohio River Community HEC-RAS Model

World Environmental and Water Resources Congress 2010, 2010
In this paper we describe the Ohio River Community HEC-RAS Model (Model) and include some preliminary results. The Model is a cooperative effort involving the U.S. National Weather Service (NWS), Ohio River Forecast Center (OHRFC) and the U.S. Army Corps of Engineers (USACE), Great Lakes and Ohio River Division (LRD), Water Management Division. Initial

River Flow Simulation Based on the HEC-RAS System

2017
This work considers the problem of river floods, and presents a computer solution that can be used to predict such a threat. The basic tool, called Hydrologic Engineering Centers for River Analysis System (HEC-RAS), and created by the US Army Corps of Engineering, is well developed; and the models created in the system HEC-RAS are quite realistic.
