Costanza:
You may want to see my dissertation that discusses this issue, and contains
much data:
Pitt, R. Small Storm Urban Flow and Particulate Washoff Contributions to
Outfall Discharges, Ph.D. Dissertation, Civil and Environmental Engineering
Department, University of Wisconsin, Madison, WI, November 1987.
In addition, you may want to see some of my early EPA reports (that are
available on the EPA web site at:
http://www.epa.gov/clariton/clhtml/pubord.html that has many EPA ORD
reports of interest. A couple of my reports that may be of interest to you
include:
Pitt, R. Characterizing and Controlling Urban Runoff through Street and
Sewerage Cleaning. U.S. Environmental Protection Agency, Storm and Combined
Sewer Program, Risk Reduction Engineering Laboratory. EPA/600/S2-85/038. PB
85-186500. Cincinnati, Ohio. 467 pgs. June 1985.
Pitt, R. Demonstration of Nonpoint Pollution Abatement Through Improved
Street Cleaning Practices, EPA-600/2-79-161, U.S. Environmental Protection
Agency, Cincinnati, Ohio. 270 pgs. 1979.
Unfortunately, many other reports (by me and others) that may also be of
interest to you are in the gray literature and are not easily available . I
have attached a summary table on accumulation rates and max. loads observed
that I have prepared from numerous (earlier) studies that will be published
in an upcoming book.

Subject: build up in urban basins
Hi all
I would like know if anybody has been concerned with the problem of the
accumulation on an urban basin never, and more particularly, if he/she has
stayed valued the possibility of an asymptotic course of the accumulation
with increase of the dry time, or a course always increasing, or straight
decreasing, having held in account also the casualties cause from the wind
and from the traffic (for example); in each case I would like know if
anybody (admitting an asymptotic course of the accumulation) he/she has
conducted a study never for appraise what values of dry time go well to
consider the basin to the his maximum state of accumulation.
Thank you very much!!
Costanza Aricò
