[Greenbuilding] quick tools for calculating rainwater run-off?

[Erin Rasmussen]

Boy, I've been diligently insulating at my house for the last couple of
weeks, and thinking of you folks for inspiration only to find that in my
absence you've been talking about sending Martha Stewart to outer space. ;-)


 

I live in a low spot, and we've got rainy conditions for 2/3 of the year.
Does anyone have any good cheat sheets for figuring out how much rain water
(in gallons) are coming off my roof, lawn and land? I've got to install some
type of additional drainage system and i'd like to add rainwater catchment -
but I'm not sure what scale I should be looking at.

 

Total roof area is about 1000 square feet (including the garage) and it's
about 0.15 acre but I should calculate for 0.25 acre to include run-off from
the neighbors.  Daily rainfall is typically 0.5-1 inch but it's not unusual
to have 3-4 inches in a 2 day period.
