Design Considerations Common To All Permeable Pavements
Impervious cover in watersheds without controls result in increased stormwater runoff and decreased groundwater recharge in response to rainfall events. This increased runoff can be the...

Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....

Mitigation of Impervious Surface Hydrology Using Bioretention in North Carolina and Maryland
As an increasingly adopted stormwater best management practice to remedy hydrologic impairment from urban imperviousness, bioretention facilities need rigorous field performance research...

Estimation of Curve Numbers for Concrete and Asphalt
All impervious surfaces are assigned a Curve Number (CN) of 98. However, no field or experimental evidence exists (to our knowledge) that shows why the impervious CN was assigned a value...

Hydrologic Comparison of Four Types of Permeable Pavement and Standard Asphalt in Eastern North Carolina
A permeable pavement parking lot in eastern North Carolina consisting of four types of permeable pavement and standard asphalt was monitored from June 2006 to July 2007 for hydrologic...

Diffuse Pollution in Oxford (Ohio, USA) Watershed and Performance of Street Sweeping as a Best Management Practice (BMP)

Evaluating Cryptosporidium and Giardia in Urban Stormwater

Lamb Island Tributary Stormwater Treatment Project — A Demonstration Site for Agricultural Runoff Management and Best Management Practices

Relationship of Hydrologic Soil Groups to Curve Number: Results of a Study

Effects of Prior Rainfall and Storm Variables on Curve Number Rainfall-Runoff

Plot and Small Watershed Scale Modeling of Infiltration and Runoff on a Semiarid Grassland Using Distributed Green and Ampt Infiltration Parameters

Firepower
The processes put in place by water utilities are designed with the quality of water normally received for treatment in mind. But the runoff from areas ravaged by fire can degrade that...

A Retrofit for Long Lake
To reduce the effects of storm-water runoff on Long Lake, in Littleton, Massachusetts, the town is implementing a variety of low-impact solutions within the lake's highly...

Panel Discussion on Stormwater Issues in Pennsylvania
The management of stormwater in Pennsylvania has radically changed over the last several years due to the concern of the citizens of the Commonwealth, and the advent of NPDES Phase II....

Storm-Water Strategy
Water pollution laws are certainly nothing new, but increased public scrutiny, beach closures, and media coverage—particularly in Orange County, California—have placed new pressures on...

A Guide for Best Management Practice (BMP) Selection in Urban Developed Areas
With the ongoing NPDES Stormwater Permits, TMDL programs, and the increase in environmental awareness, many municipalities are challenged to address the relatively new concept of cleaning...

Shape of Storm Pollutograph from the Four Different Rural Watersheds
(Abstract only) Just as a hydrograph describes the flow rate of water for a storm event, a pollutograph shows the rate at which pollutants dissolved or suspended in the runoff are transported....

How the Impacts of Urbanization Are Being Addressed in the Los Angeles River Watershed
Due to an increased interest and concern about the Los Angeles urban environment, studies have begun to focus on the local water cycle and the impact of impervious land on the Los Angeles...

Design Considerations for the North Railroad Alluvial Fan Levee System in Boulder City, Nevada
This paper presents a drainage study for a flood control levee system in Boulder City, Nevada. This levee system is located below an alluvial fan watershed and was proposed to protect...

Progress Report: ASCE Task Committee on State of the Practice in Curve Number Hydrology
In response to a growing awareness of the role of the Curve Number method in engineering and environmental impact applications, and its limitations, the Committee was formed in late 1997,...
