Thanks guys - and your right, I think I may be over-complicating this. It's just that I've seen thru other programs and reports the 10-day hydrographs and volumes from HydroCad and CivilCadd etc and I was wanting to replicate using HEC-HMS.
But yes, I am thinking of interpolating the precip...
Thanks Smiah for the reply: (been out in the field and saw a reply :)
What I have for precipitation data is the Point Precipitation Frequency Estimates form NOAA Atlas 14 (see attached). I don't have any incremental (interval) precip depths vs. time.
Can this data be input as a viable...
Hello all:
This may be long winded, but I hope not. My vision is blurry, my hair frazzled, eyes are red all because I'm trying to figure out, what I thought would be an easy expected runoff volume, to be retained within a terminal basin. I'm pretty good with hydraulics (intermediate) but a step...
Okay guys - thanks for the help/input. I think I am just going to input all the values into the outlet dialogue boxes for the orifices, weir overflow, 30" Culvert (orifices and weir flow into this [see previously attached image] - I just wish there was a toggle or something that I could switch...
SMIAH:
Thanks for the response. I do follow you that I can specify various outlets and types set at different elevations etc. What I will have is a 60" Manhole with 3 orifices punched in the side at various invert elevations and diameters. From this manhole, the ultimate discharge will be thru...
Hello all:
I've often lurked this site many a time for answers to my questions - I had to "join" to post so here I am. I am trying to set up a multi-stage outlet structure in the HEC-HMS program (pretty simple in Hydraflow-Hydrographs). Is this possible in HEC-HMS 3.5? I don't theink the...
