Attached is a new project I made of the same stream. Reduced the number of cross sections and greatly simplified the cross section geometry. Still running into the same issues.https://files.engineering.com/getfile.aspx?folder=98329cbf-23d4-46d2-89a6-85d8d34f4afe&file=Creek2.zip
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...
Attached to my original thread is a PDF with various screenshots from HEC-RAS & CAD as well as some photos from the field to help show what I'm working with. Here is one more showing a close up of the geometry so you can see how I cut the XS around the bridge.
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...
