Version 5.0 of the River Analysis System (HEC-RAS)

[المشرف العام]

Version 5.0 of the River Analysis System (HEC-RAS) is now available. This Version supersedes Version 4.1, and all previous versions. Several new simulation features have been added to the software since that time. Version 5.0 of HEC-RAS includes the following new features:

1. Two-dimensional and combined one- and two-dimensional Unsteady Flow Modeling
2. New HEC-RAS Mapper capabilities and enhancements
3. Automated Manning’s n value calibration for one-dimensional Unsteady Flow
4. Simplified Physical Breaching algorithm for Dam and Levees
5. Breach Width and development time calculator
6. New Hydraulic outlet features for Inline Structures
7. Sediment Transport Modeling Enhancements: Including Reservoir flushing and sluicing, as well as channel stability using BSTEM integrated within HEC-RAS
8. Water Quality Modeling Enhancements
9. Completely new two-dimensional User’s Manual
10. Several new example applications within the Applications Guide
11. Updates to User's Manual, Hydraulic Reference Manual, Applications Guide, and Help System

Other minor enhancements were also added. The development team has also continued careful and systematic testing of the software since the last release. The results of that testing in combination with reports from users has allowed the identification and repair of various problems. Some minor problems that did not affect results but caused problems in the software interface have been repaired without being specifically documented. For more information on What's New and Bug's fixed from the last version, see the HEC-RAS 5.0 Release Notes
