National Highway Runoff Data and Methodology Synthesis. Volume 3: Availability and Documentation of Published Information for Synthesis of Regional or National Highway-Runoff Quality Data;Final rept. Oct 96-30 Sep 01

摘要

Knowledge of the characteristics of highway runoff (concentrations and loads of constituents and the physical and chemical processes that produce this runoff) is important for decisionmakers, planners, and highway engineers to assess and mitigate possible adverse impacts of highway runoff on the Nation's receiving waters. This report describes the NDAMS report-review process, summarizes results of this metadata review process, and provides an interpretation of these results. The evaluation of available literature includes reviews of 252 reports, including 34 literature review or summary reports and 218 detailed reports. Evaluation of many individual documentation elements indicates that the available literature does not properly document research to a degree that would establish that existing data are valid, comparable, or technically defensible for regional or national synthesis. Furthermore, when individual metadata requirements are combined, the proportion of available reports that meet these multiple criteria quickly decreases to the point where regional or national synthesis is not possible. This paper is one volume in a three volume series. The titles of these volumes are: FHWA-EP-03-054 Volume I--Technical Issues for Monitoring Highway Runoff and Urban Stormwater FHWA-EP-03-055 Volume II--Project Documentation FHWA-EP-03-056 Volume III--Availability and documentation of published information for synthesis of regional or national highway-runoff quality data.
