I am computing peak runoff from a development site using HydroCAD. The New Jersey code has the following requirement
"In computing stormwater runoff from all design storms, the design engineer shall
consider the relative stormwater runoff rates and/or volumes of pervious and
impervious surfaces separately to accurately compute the rates and volume of
stormwater runoff from the site."
I see, there is an option in hydroCAD to do just that
settings -> calculations -> Advanced - > Calculated separate Pervious/Impervious runoff (SBUH weighting)
But it seems like this option is tied to Santa Barabara Unit Hydrograph
Can I use this option, even when I am using a Delmarva Hydrograph?
