Hi,
i am working on a model for a small neighbourhood
after i have input all the data ( elevations, catchments area , Tc, ... )
we are trying to imploy SCS curve method.
but when i have chosen the implicit engine it shows that the only engine that make sizing and design for invert levels is the rational engine.
is it true that i have to use Rational method only for pipe sizing and invert level desin?
Regards
