Thanks for your help. The model I am using is HEC-HMS. The only way I know how to define the pond area and curve number is by using the subbasin option.The subbasin option also requires a Tc. And for a pond, of say, 200 acres without offsite drainage, using a zero Tc (not allowed by the...
I have been trying to model a pond. The pond's only source of water is from direct precipitation. The program I am using requires a time of concentration(Tc)to route the hydrograph through the pond. Without an offiste drainage area, is it okay for me to come up with a Tc within the pond?
