SEDCAD 4 for Windows
Copyright 7996 Pamela J. Schwab
Civil Software Design

This SedCAD run is to represent the expected runoff and sediment
generated from 2002 forward. The area was most recently
reseeded and mulched in 1997 with a good stand of grass
currently in place.
• Curve numbers and erosivity factors reflect the soils replaced on
the refuse area and that naturally occurring on the undisturbed
portions of the watershed. Water quality was modeled using pond-
full scenario for purposes of demonstrating treatment instead of
storage of runoff. Factors reflect conservative assumptions
throughout these calculations.
