Request ability to use custom S-curves similar to HEC-HMS. This would allow us to import custom S-curves rather than use default SCS DUH's for example. I'm in Southern California and the local Districts are very picky and use unique hydrology appr...

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...
