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 […]
Many water surface profile software programs prior to HEC-RAS had a quirky rule against having perfect vertical sides. In other words, you could not have two or more elevations at the same stationing. A perfect example of this is a rectangular flume. The workaround for the older software was to define the tops of the […]
