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...

Asphalt Parking Lot Runoff Nutrient Characterization for Eight Sites in North Carolina, USA
The objectives of this study were to characterize asphalt parking lot runoff quality and determine factors influencing nutrient concentrations and loads. Event mean concentrations (EMCs)...

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...

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...

Evaluating Cryptosporidium and Giardia in Urban Stormwater

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

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

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

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

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

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...

Assessing Long-Term Pollutant Concentration Trends in Urban Runoff for TMDL Planning and Regulatory Assessment
Loads of some pollutants in many urban watersheds include a substantial component originating with non-point sources and stormwater runoff. TMDL planning includes estimating those loads,...

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...

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...

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,...

Erosion from an Industrial Forest Road in the Ouachita Mountains of Southeastern Oklahoma
Erosion from 4 segments of a 2-year old forest road in a 740 ha basin was measured for each of 105 storms that occurred in a 3.5 year period. Two road segments were part of a mid-slope...

The Watershed Modeling System
The Watershed Modeling System (WMS) is a comprehensive environment for hydrologic analysis developed by the Environmental Modeling Research Laboratory (EMRL) at Brigham Young University...
