Just heard from HEC that a new, updated beta version of HEC-RAS 5.0 will be coming out soon (later this month or early next). The full release of HEC-RAS Version 5.0 is still scheduled for the end of the calendar year.
New features in the next beta release are:
- Multiple Manning's n value definition in 2D areas
- Velocity Vectors in RAS Mapper
- Particle Tracking Visualization Tool in RAS Mapper
Here’s a sneak peak of a new velocity visualization feature in HEC-RAS used in an “instantaneous” dam break example, courtesy of Gary Brunner.
