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...
Minimum Design Loads for Buildings and Other Structures
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)...
The Case for Cleaning
When sanitary sewer systems overflow during heavy rainstorms, the crisis is often attributed to the sheer volume of water inundating the system. In many cases, however, the lines would...
Amino Acid Geochronology Applied to the Dating of Eolianites on San Salvador Island, Bahamas
Using amino acid racemization data measured on carbonate eolianite sediments, we assess the ability of amino acid geochronology to distringuish among several stratigraphic units on San...
Rain and Gray Water Reuse Systems: The Hazard of Legionaries Disease
The Legionaries Disease is being more and more diagnosed. This infectious disease occurs when humans come in contact with the aerosol of contaminated water. The body of knowledge is growing...
Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...
Basin Response Time: Potential Hydrologic Basin Handprint
Hydrologic lead time is an important factor in many water resources engineering applications. The determination of the response time of a watershed to runoff-producing rainfall is the...
After the Rain Has Fallen
Ground Water Management Symposium
This proceedings,
Leachate Chemistry: Its Implications for Clogging
The clogging of leachate collection systems is controlled by interrelated mi and chemical phenomena. Mesocosms containing landfill materials and simulating leachate collection were infiltrated...
Protecting Drinking Water: Rapid Detection of Human Fecal Contamination, Injured, and Non-Culturable Pathogenic Microbes in Water Systems
The rapid, potentially-automatable extraction of filter retentates has allowed quantitative detection of the unique biomarker for human fecal contamination, coprostanol, and the signature...
Automated Tools for Spatially Distributed Rainfall/Runoff Modeling
A watershed modeling system (WMS) has been developed to address the needs of surface water rainfall/runoff computer simulations. WMS, developed at the Engineering Computer Graphics Laboratory...
Status Report ? Task Committee on GIS Models and Distributed Models of the Watershed
In recognition of the trend toward the adoption of geographic information system (GIS) technology in analyzing hydrologic problems and the obvious applications of GIS in incorporating...
Fatigue Damage Accumulation Under Stochastic Stress Histories
An extensive simulation study was performed to generate random Gaussian stress time histories from power spectral densities (psd's). The psd's of time histories were selected to represent...
Peak Runoff Prediction for Small Rural Watersheds
A regression model for peak runoff prediction from small rural watersheds was developed using the rainfall/runoff data collected from 43 watersheds in the front range of the State of Colorado....
Effect of Nonstandard Rainfall Distributions on Stormwater Management Detention Basins
A rural watershed is modeled to determine the effect of varying rainfall patterns on stormwater management detention basins designed for center peaking events. A hydrologic model of the...
Design Aspects of Modeling Reclaimed Water Use
The authors compare design aspects of modeling reclaimed water use with monthly and daily water balance protocols and review state regulations pertaining to use of reclaimed water. The...
Heuristic Knowledge-base Approach to Runoff Estimation in Midwestern States Using a SCS Curve Number Method
The applications of the Knowledge-Based engineering has emerged as a potential technique for incorporating human expertise and some degree of intelligent judgment into decision-supporting...
A Study of Alkalinity Leaching and Residual Strength of Alkaline Stabilized Sludge
The addition of sufficient amounts of quicklime or other alkaline earth oxides to dewatered sludge raises both the pH and temperature of the sludge, resulting in microbial inactivation....
Threshold Precipitation Events and Groundwater Recharge
Data from two study sites on the Nevada Test Site, Nevada are used with precipitation data from other long-term precipitation gages to identify the frequency of precipitation events that...
