Bioretention Underdrain Slope / Additional layer Options

Virginia specifications for a bioretention requires the underdrain to have a slope to it, but Infodrainage slope does not allow for this in the SWC bioretention SWC. Also, we sometimes have to place the underdrains in a trench below the storage la...

Time of Concentration (TR-55) Calculator

Although the software has a TR-55 calculator for time of concentration, it doesn't work properly and also needs additional options added. Currently it isn't functional, because the software doesn't allow you to use only 1 or 2 of the 3 flow condit...
