Thanks psmart for your comments. I guess I need to step back and consider what I am really trying to accomplish with my modelling a little more and how an underdrain alters how much credit I can give these old ponds towards meeting current requirements.
I know how to model a standing pool, but I was looking to see if there is any way to model the slow dewatering of the pond below the bottom most orifice (say on a riser) that is only affected by the underdrain. I am trying to do so as accurately as I can given the information I am reasonably...
Thank you psmart and LHA for your comments. I agree that it is best to model all the discharge influence. I mentioned in my original post that I am dealing with existing infrastructure. More specifically I am looking at systems that somebody else designed and installed, in many cases a decade...
I am wondering about the best way to model a pond underdrain. The set up I am thinking of would involve a perforated pipe buried in gravel at the bottom of the pond, connected to an outlet riser and culvert. There are a few ways that I could see this modeled:
1)The “model everything approach”...
I am modelling a pond (pre-existing) and was wondering about the best way to model my outlet device. Like many structures I see, this one has a concrete riser with a couple of small holes drilled in the sides and big hole on top which has been fitted with a grate, much like you would see on a...
Thanks TerryScan. Are you suggesting that there be three separate storage nodes then? The only problem with that is that I need to push water uphill to get from node to node and it sends me error messages stating that my water elevation is exceeding previous nodes.
I am trying to put an existing stormwater management system into HydroCAD, but am at a loss as to how to begin.
The runoff at the site in question is collected via catch basins. All the catch basins are connected via perforated pipes laid level at 322.17'. Some of the catch basins are also...
