Rainfall Infiltration-Induced Landslides

Estimating Slope Stability Reduction due to Rain Infiltration Mounding
(Originally published in J. of Geotechnical and Geoenvironmental Engineering 2006, 132(9), 1219-1228.)...

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...

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...

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...

Power Shift
Engineers designing a Manhattan skyscraper with offices in the lower floors and residences in the upper found that they had to employ several unusual methods to accommodate client needs....

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...

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,...
