Hi: Does anyone have a good reference for an appropriate curve number representing disturbed soil with temporary stabilzation consisting of hay mulch or an RECP? Thanks.
Hello, I am modeling a concrete riser and grate in a detention pond. The 30 inch diameter grate on top of the riser will be angled to match the 3:1 slope it is embeded in. I am not sure the best way to model this angled outlet.
I have set up a runoff model in support of a snowmaking feasibility study. I am trying to determine what specific rainfall events would be most appropriate to model to best evaluate available surface runoff volumes for snowmaking. I also wonder if it would be appropriate to include...
Hello,
Does anyone have a suggestion on appropriate CN to use for multiple wetland areas, which are included in a large scale modeling analysis? The wetland areas appear to hold permanent pools of water based on orthophotography, although I'm hesitant to assign a high CN such as 98 or even 100...
Hello,
I am trying to model a large roof (3.5 acres) and the roof drain pipe receiving the runoff. I do not have data on the size and exact number of vertical pipes draining the roof, but suspect they are not the controlling factor in the model because there are so many of them. I do have...
Hi group,
I'm trying to model an open channel as a pond structure, since I would like to account for exfiltration via an under drain along the swale, and a raised outlet structure at the discharge point of the channel. I notice that it is possible to model a horizontal cylinder with a sloped...
I'm trying to model the effects of both an inlet grate at the surface and an outflow pipe in a catch basin. I understand that catch basins are typically modeled as zero storage pond structures, however, I'm unsure about how to set up the routing to evaluate both of these controls.
Thanks in...
