Hello Panel,

I would like to request some clarification regarding the "ponding
allowed" flag in EXTRAN of SWMM. I am using Visual SWMM.

When a node goes into surchage with the ponding flag on, is head being
calculated on the system based upon the ponding depth at the node?

And my second question is under Junction Defaults in the Extran Job
Control the ponding area equation is defined as:

ponding area = (constant) e ^ (ponding depth)

where the ponding depth is entered as a constant. Please clarify this
for me, as the equation would seem to make more sense if the exponent
was a variable (variable depth).

Thanks!
