While no date has been set for the release of Version 5.1, it is expected sometime within the next year or two. But no guarantees! This will be an exciting new addition to HEC-RAS in that users will no longer […]
Expanding upon Chris’ discussion of where to place bank stations, what should you do about high terrain somewhere in the middle of your cross section? Here is an example: How should we treat the left overbank? It’s hard to tell if the high area next the left bank is isolated (i.e., it would be an […]
Lately, I’ve seen a lot of basic bank station issues for models I have reviewed. Some real basic stuff. So I thought it would be good to go back to the basics a bit here and review proper placement of bank stations for cross sections in HEC-RAS. What do bank stations do for us? First […]
Ahead of the wide-scale implementation of the 2-dimensional (2-D) modeling module in HEC-RAS, I wanted to share a quick tip that will be useful for editing your 1-dimensional (1-D) HEC-RAS model to prepare to couple your 1-D channel with a 2-D overbank area. It’s common to have a cross section with a well-defined channel and […]
