Pollutant Loadings and Impacts from Highway Stormwater Runoff. Volume 2. Users Guide for Interactive Computer Implementation of Design Procedure

摘要

The report is one of four final documents of an investigation dealing with the characterization of stormwater runoff pollutant loads from highways and the prediction of water quality impacts they cause. The study results are based on monitoring data from 993 individual storm events at 31 highway runoff sites in 11 States. Impact prediction is based on a methodology previously developed and applied to urban runoff and adapted for highway runoff applications. The document is a users guide for an interactive computer procedure for computing the estimated impacts on water quality of a stream or lake that receives highway runoff. The program provides guidance for evaluating whether or not a water quality problem will result, and the degree of pollution control required to mitigate predicted impacts to acceptable levels. The computer program is based on the methodology presented in the Design Procedures report of the study.
