Short Description

The purpose of this user's manual is to size storm water control facilities that mitigate the effects of increased runoff (peak discharge, duration, and volume) from a proposed development on a stream using a computer model that represents the following:
• a uniform method for western Washington
• a more accurate method than single event design storms
• an easy-to-use software package

Abstract Long Description

The purpose of this user's manual is to size storm water control facilities that mitigate the effects of increased runoff (peak discharge, duration, and volume) from a proposed development on a stream using a computer model that represents the following:
• a uniform method for western Washington
• a more accurate method than single event design storms
• an easy-to-use software package

The computer program is based on:
• continuous simulation hydrology (HSPF)
• actual recorded precipitation
• measured pan evaporation
• historic vegetation
• regional HSPF parameters

Parameter values can be modified for local conditions.
