I've recently started a new job as a civil engineer at a DOD agency. I've been working as a civil engineer since 2005 and while I've performed many calculations by hand, as with most of you, I used software applications to crunch numbers at my last job. Specifically, I used stormcad for HGL...
I'm working on a HEC-RAS model to support a CLOMR application. Our design proposes a grandstand at the west end zone of a football field . The end zone is currently in the 100-YR flood plain. A stream runs adjacent to the end zone and the grandstand will be between the end zone and the stream...
We have an existing steady model we’re working with. We don’t have the hydrology, only the HEC-RAS files with the steady flows (peak flows of course). We need to make some sort of change to the channel and/or floodway to lower the 100-YR WSE in the vicinity of an existing college football field...
I’m working on several HEC-RAS models for a drainage study. Our stream restoration team has conducted geomorphic surveys of the stream channels. The spreadsheet used for this process provides output that includes bankfull flowrates. The 1.5 year event is said to be responsible for bankfull...
Does anyone know of a good set of instructions to provide surveyors collecting HEC-RAS field data? Our surveyors have not collected field data for HEC-RAS model input before. I'm sure I could let them know what's needed but perhaps someone out there has already gone through this. I'm not being...
I'll be brief here. I'm constructing a HEC-RAS model and I'm wondering what the best source for water surface elevation (WSE) is. It's been a while since I've used this application but I think I need to establish a boundary condition for each storm event I plan on "running". In my case, flow is...
