Pervious Pavement Modeling- Tc Method

Pervious Pavement Modeling- Tc Method

Pervious Pavement Modeling- Tc Method

Hi All,

Quick question:

HydroCAD has a helpful article at the address below which describes a method for modeling pervious pavement using a longer Tc, per research performed by the UNHSC.

I have searched the UNH website for the actual study and have been unable to find a copy. I am interested in how they arrived at their values and I need information to support the approach of using a proportional Tc based upon 790 minutes per 41" subbase depth. Does anyone know where I can find a copy of the original report on the UNH website? I can contact UNH directly, but I am hoping that it is on their website somewhere.



RE: Pervious Pavement Modeling- Tc Method

The HydroCAD web page you mentioned is based on details provided directly by researchers at UNH, which may not be published on their web site.  HydroCAD support can provide additional details, but you may want to contact UNH directly for the most authoritative information.

Thanks Peter!

RE: Pervious Pavement Modeling- Tc Method

If you find this study, I'd love a copy.  As an ex-pavement design technician turned site hydrologist, I could really sink my teeth into a study like that.  Contact info is in my sig.
