Has anybody modeled a roadway as a custom weir? I would like some advise on how to accomplish this. Thanks

thread564-110180 Sam, Sorry I didn't get back to you earlier but you can find the forum I mentioned at http://discussion.bentley.com/

Has anybody tried to model an arch pipe or anything other than the standard circular or rectagular as a culvert outlet? If so, I'd sure like to find out how you did it. Thanks

sam, I think you'll find many more responses at Bentley's Discussion Forums.

I just completed using Site 2004 for a streetscape project and was generally pleased with it. However, there were some "quirks" that we had to work through. For example, occasionally, when projecting a line at a certain slope from a reference element, the elevations of the child would default...

Has anybody found a way to model unconventional orifices in HydroCAD? For example, I want to partially block a round pipe with a concrete weir and don't know how to model it as an orifice.

psmart (Civil) Aug 15, 2004 Why do you need a 500-year depth? If you are dealing with regulations that cite a 500-year event, they should also give you a source for the rainfall data. I thought the same thing but that is what my boss wanted.

Thanks Iha I ended up using a USGS formula that estimates stream discharge based on location and area. I then altered the rainfall depth to approximate the discharge for the basin in question.

I haven't had much luck finding 500-yr rainfall depths for use in the NRSC method. Does anybody have any suggestions?

I have a situation where I need to use DSI as I have coupled ponds but the final outfall into a creek needs to be modeled with a constant tailwater elevation. Anybody have suggestions?
