I am new to lateral structures. That said, I am trying to model a lateral culvert between two minor drainage channels linked by a culvert. The flow in the channels are not inter-related and the channel that is at the downstream end of the culvert has negligible flow (0.3 m3/s) compared to the...
Took a dig at exporting a fictional river reach modeled in Cvil 3D 2011 to HEC RAS. As the attachment will show something went wrong somewhere as indicated by a discrepancy between geometric editor and the reach length table in HEC RAS:
Flow direction in Civil 3D is from 0+12.94 (U/S) to 0+116.6...
I need to determine the diameter of a proposed culvert for a given roadside ditch. In HY-8, how do I account for counter-sinking of culverts below stream bed:
a) inlet to 40% of diameter,
b) outlet to 20% of diameter
Thanks
Torn between HY-8 and HEC-RAS to model a culvert to carry about 1 m3/s under a road embankment with a allowable headwater of 1.5 m. The topo survey covers some 50 m radius from the middle of the proposed alignment of the culvert. The road embankment will be located in the middle of a pasture...
As the title suggests...
I would like to hear from people with experience in at least XPSWMM and PC SWMM about their take on the softwares. The local municipality will accept only DDSWMM but we would like to make a case for either PC SWMM or XP SWMM. All I have heard through the grapevine is...
Have a few questions for HEC-RAS pertaining to the attached river schematics.
1. I need to know from where the "Main Channel Distance" appearing as the horizontal axis title in the second attachment is measured. Is it going from 8 to 19, or otherwise?
2. I have a bridge located about midway in...
