I've built a HEC-RAS model for a stream I'm analyzing and can't seem to figure out why I'm getting persistent warnings for nearly all my cross sections. Initially I nearly doubled the amount of cross-sections, since most warnings said this typically indicates the need for more sections. At this...
I'm working on a HEC-RAS model for a stream running around the perimeter of a property we are designing a subdivision on. We will be cutting/filling in floodplains to manage the floodplain elevation and my proposed HEC-RAS model seems to be running smooth.
In trying to accurately model the...
I'm working on a HEC-RAS study for a new subdivision. On either side of a good portion of the stream there are farm fields as soon as you get into the floodplain. Trying to determine an appropriate Manning's n to use for the floodplains in the area; it appears I need to determine if the crops...
