#HIGH CORD HEC RAS LOW CORD SOFTWARE#
The software also contains tools for performing inundation mapping directly inside the software. The current version of HEC-RAS supports Steady and Unsteady flow water surface profile calculations, sediment transport computations, and water quality analyses. In addition to the four hydraulic analysis components, the system contains several hydraulic design features that can be invoked once the basic water surface profiles are computed. A key element is that all four components use a common geometric data representation and common geometric and hydraulic computations routines. The HEC-RAS system contains four hydraulic analysis components for: (1) steady flow water surface profile computations (2) One and two-dimensional unsteady flow simulations (3) movable boundary sediment transport computations and (4) water temperature and constituent transport modeling. The system is comprised of a graphical user interface (GUI), separate hydraulic analysis components, data storage and management capabilities, graphics and reporting facilities. HEC-RAS is an integrated system of software, designed for interactive use in a multi-tasking, multi-user network environment. ABSTRACT The Hydrologic Engineering Center's (HEC) River Analysis System (HEC-RAS) software allows you to perform one-dimensional steady and 1D and 2D unsteady flow river hydraulics calculations.
