It appears that the two programs definitely calculate culvert capacity differently, but the differences are too far apart to rationalize. PCSWMM (EPA-SWMM under the hood) and HEC-RAS are great tools. HEC-RAS is the standard for open channel modeling. Unless you are modeling closed systems (more than culvert/bridge crossings) or if your area is pancake flat, I would continue to use HEC-RAS.

• From HEC-RAS Geometric Data window, under File, select Import Geometry Date, only geometry file can be imported, you have the options to select whole geometry file or some items in a geometry file. Simulating Each Plan 2021-4-21 · I've had enough experience now using AutoCAD Civil 3D and HEC-RAS for 2D flow modeling in Maricopa County Arizona to share a list of best practices. It's only a small beginning, but it's something. Enjoy.

Nov 13, 2018 Hello , I was wondering if someone could direct me to HEC-HMS and HEC-RAS resources I could use to learn how to use those software Jun 1, 2012 Given that flood control is one of the primary reasons for HEC-HMS and HEC- RAS existence, I'm inclined to think that HEC-RAS and HEC-HMS Jul 18, 2018 and focuses on HEC-RAS 2D modeling capabilities.

drainage study. I first ran HEC-HMS, then HydroCAD to get a quick sense of the storage volume required. I haven't really gotten far into either, but HEC-HMS is more intuitive than SWMM and interfaces with HEC-RAS, whereas SWMM can do water Dec 19, 2017 The HEC-HMS program uses the size, slope and vegetation of the land How do we present HEC-RAS Modeling Results Presented to the Community? see the existing condition versus the impact with the project in place.
