I'm working on a large watershed model in HEC-RAS and having a discussion about whether it is better to use effective area to show areas of no flow or to use use levees to show where the flow should go. My question is "If you use effective area aren't you discounting HGLs in the main channel if...
I am trying to plot out my results in HEC-RAS and decided to adjust a scale on one of my profiles to make the node point names easier to read. This worked through the Graphic Plot Options -scale function, however I can't seem to get it back to the defaults where the program chooses the limits...
I'm trying to import a tributary to an exisiting line (HEC-RAS channel) but having problems marrying lines together. The line imports but is not connecting to the existing system merely sitting next to it or overlaying the line. Wondering if anybody has solved this problem. I have created a...
Hello - I have a rather large HEC-GeoRAS model and I am getting the -2147467259 message, however, when I reduced the size of the data base I continue to get the message. I'm wondering if anyone else has experience with this message...THanks
I'm in HEC-RAS and trying to break a river and then delete the segment. Does anyone know if I can do that? Basically I want to cut off my model not a node and therefore want either add a junction and create a new reach, that I will then delete, or find a way to delete a section of river.
I am running a large watershed in HEC-RAS. The Errors, Warnings, and Notes are telling me I have divided flow when I have a single open channel. The only thing I can think of is that energy line is above the roadway which is somewhat off-set and sloping away from the channel which could...
Looking for a process to join several HEC-RAS files together for a system wide evaluation. Some way to take stream reach cross-sections and combine with other reaches without doing manual input. Can anyone help?
