Sources of Urban Pollutants?Do we Know Enough?
The non-USGS data from the NURP program are summarized in terms of their availability and adequacy for decision making and modeling. Results of selected projects are reviewed and related...
Urban Runoff and Water Quality Criteria
The significance of water quality impacts from urban runoff could be judged on the basis of existing water quality criteria developed to control continuous point source discharges. Wet-weather...
Pollution Sources and Potential Impacts?Next Steps
The paper presents the propositions that there is much to learn about what determines the magnitude and variability of pollutant loads in urban runoff; and with the exception of nutrient...
Potential Impacts on Receiving Waters
As a discrete source of water-borne pollutants that are discharged to receiving waters, urban stormwater runoff can be and has been in specific instances a source of water quality problems....
Impacts of Urban Runoff on Estuarine Ecosystems
This paper first attempts to characterize the types of pollutants which could be expected to enter an estuary from urban runoff. Then, based on existing knowledge of the impacts of various...
Urban Runoff Impacts on Receiving Waters
Urban stormwater runoff contaminants affect the principal receiving water uses of: (1) public water supply, (2) recreation, (3) protection of aquatic life forms, (4) agricultural and industrial...
EPA's Perspective of Urban Nonpoint Sources
The overall goal of the Nationwide Urban Runoff Program (NURP) was to develop information that would help provide local decision makers, States, EPA, and other interested parties with...
Infiltration as a Stormwater Management Component
This paper discusses the implementation of infiltration practices in Maryland. The benefits of infiltration are briefly discussed along with the regulatory background. Standards and Specifications...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Runoff Controls in Wisconsin's Priority Watersheds
The Wisconsin nonpoint source program is becoming more heavily involved in urban runoff controls. About 3 million of state cost sharing money has already been allocated to controlling...
Cost of Urban Runoff Quality Controls
This paper attempts to provide guidance in the evaluation, selection and planning of various BMPs by comparing their costs and cost-effectiveness, in terms of pollutant removal capabilities....
Detention and Retention Controls for Urban Runoff
The operating principle for retention devices is the interception and capture of runoff, preventing its direct release to surface waters. The most common mechanism by which captured runoff...
Workshops on Research and Future Activities Needs
During the conference, a questionnaire listing proposed topical areas was given to participants, along with instructions to indicate their first three preferences and to propose additional...
Lognormality of Point and Non-Point Source Pollutant Concentrations
This paper presents a series of probability plots of water quality data from a variety of discharge sources. It is intended to provide a visual display of the appropriateness of characterizing...
Estimation of Pollution from Highway Runoff?Initial Results
One of the first tasks in the present effort was to assemble a data base of highway runoff characteristics. In the paper that data base is described, the data are summarized, and best...
The Training of the Owner
Engineers would do well to explain to their clients just what the role of the engineer is. The place to start is with one's ability to produce a perfect set of plans. Imperfections...
Cut-and-Fill Becomes Cut-and-Drain
The U.S. Navy's facility in Subic Bay, Philippines, is in a mountainous area which experiences 182 inches of rain per year. These factors plus weak soil, made necessary an...
Urban Runoff Quality
Impact and Quality Enhancement Technology
This book contains the papers presented at the Engineering Foundation Conference, Urban Runoff Quality, held June 22-27, 1986 in Henniker, New Hampshire. Topics covered include data needs...
Proportional Weirs for Stormwater Pond Outlets
Many jurisdictions mandate that new developments must not cause runoff to flow downstream, during and after rainfalls, at rates higher than preconstruction. A common for controlling runoff...
Santa Barbara Hydrograph with Green-Ampt Infiltration
Numerous models are available to estimate rainfall-induced runoff from watersheds. The leading criteria in model selection is often reproducibility. Models that are reproducible are often...
