Thank you. As soon as I get the green light to continue with my project, I am going to try this and see what happens. Thanks again!!!

I have already modeled my drainage basins and detention pond. Can you explain how to use the special outlet device to define a pump rating curve? I have the outlet modeled as a culvert with free discharge.

Is there anyway to model a pump in HydroCAD?

Thank you...

So for a 25 year storm, should I put 25%.... and for a 50yr, 50%????

How do you change from a 10yr storm to a 25yr storm in HEC-HMS? and 25yr. to 50yr. to 100yr. etc?

Francesca... I see what you are saying about modeling the junctions, about how you need to put the reach lengths in the junction editor versus the cross-section editor (of the last cross-section near the junction). My problem with that is that I have a culvert that connects one reach to the...

Francesca, I am still working on your comments.... thanks for the input once again. I am sure that I will have more questions to come.

TerryScan, I had the lake modeled as a storage area, but I didn't know exactly what values to use for the SA. I ended up taking the lake out. My watershed drains into Lake Pontchartrain. I am not really sure on how to model this situation.

Francesca, First of all...THANK YOU so much for helping me out!!! I looked at the Hydraulics Manual and it is much better than the user's manual. It wouldn't let me check or put in and input for boundary conditions at the downstream junctions. I added a normal depth at the upstream boundary...

It is actually mainly at my upstream part. I tried to enter the downstream slope in the reach boundary conditions and it says that I can't set the slope for junctions. I have junctions where my reaches combine and flow together downstream. I have everthing ultimately flowing into a lake (I...

Am I the only person who thinks that HEC-HMS and HEC-RAS are EXTREMELY frustrating. I am still having a huge prolblem with my water surface elevation that HEC-RAS is giving me. It is showing that my water surface elevation in my watershed is about 10ft. over roads and high railroads. This...

It is the exact Q input value that I had.

Where can I look at the cross-section report? I got all of my information from a surveyor. I work for an engineering firm and I am conducting a master drainage plan for a certain area.

OK. I put the flows in like you said. The water in my watershed is draining into a huge lake. The water elevation that the program gives me is about 5 ft over my roads and over my railroad tracks. This can't be right. Can someone give me an idea on how to model this lake and everything...
