Importing HEC-2 Data - United States Army
HEC-2 is a steady flow hydraulics model that was the predecessor to HEC-RAS. Thousands of hydraulic studies were done with HEC-2 in the 70's, 80's, and 90's. Before importing HEC-2 data,...

Importing a HEC-2 Model in HEC-RAS - CivilGEO Knowledge Base
In GeoHECRAS, the Import HEC-2 Project command allows a pre-existing HEC-2 data file to be imported and converted into a HEC-RAS model, and then displayed on the Map View. Follow the steps below to use the Import HEC-2 model command:
The first HEC-2 Water Surface Profiles program was released in 1969. The capabilities of HEC-2, and other HEC programs, have evolved; primarily driven by project and application...
2005年11月5日 · HEC-2, named HEC-RAS, (River Analysis System) was released by the Corps in 1995. The later versions of HEC-RAS have the added capability to solve time dependent flows (unsteady). There are computational differences between HEC-2 and HEC-RAS so that they compute slightly different water surface elevations for the same input data.
computer programs HEC-1 Flood Hydrograph Package and HEC-2 Water Surface Profiles can be used to model the flood-wave movement through a river. By analyzing the existing conditions and the
Computational Differences Between HEC‑RAS and HEC‑2
HEC‑RAS and HEC‑2 are both software programs that are used for computing water surface elevations for rivers, streams, and other open channel networks. While both software programs were developed by the Army Corps of Engineers, the …
