Hawaii Storm Durations

[Mia at ROTH]

Hi,
We are modelling stormwater drainage in Hawaii where the typical storms are Type 1 (24 hr) storms. However, the county standards for our design site ask us to consider a 2yr-1hr storm event. How can we use Hydrocad to interpret a 1 hr storm event for a Type 1 storm?

Thank you
Mia

As we discussed directly by email, I believe your references to a 1-hour event actually refer to the Rational Method and not the Type I distribution, which is only available in a 24-hour duration.
