Development of a 2D or Combined 1D/2D Model

HEC-RAS can be used to develop a 2D Model or a combined 1D/2D model.  This section of the manual discusses the following:

Development of the 2D Computational Mesh
Creating Hydraulic Property Tables for 2D Flow Areas
Connecting 2D Flow Areas to 1D Hydraulic Elements
Hydraulic Structures Inside of 2D Flow Areas
Geospatial Coordinates for Hydraulic Outlets Connected to 2D Flow Areas
Modeling Bridges Inside 2D Flow Areas
Modeling Pump Stations inside 2D Flow Areas
Flow Roughness Factor Curves in Calibration Regions
