Expected Moments Alogrithms for Flood Frequency Analysis
The Expected Moments Algorithm (EMA) is a new but conceptually simple approach for the treatment of nontraditional data in flood frequency analysis. Nontraditional data includes censored...
Modeling Groundwater Contaminant by Unstructured FVM
This study focuses on the numerical solution of the integral form of transport equation on unstructured grids. The algorithm is developed in direct finite volume concept and constructed...
Discussions of a 3D Numerical Simulation of Transient Regional Groundwater Flow and Transport
A 3D numerical model of a groundwater flow and transport was developed to study the movement of radionuclides in the Savannah River Nuclear Site, South Carolina. The modeling effort has...
Effects of Ignoring Well Losses on the Specific Capacity Function
This paper combines these equations with the traditional step-drawdown equation to generate a more realistic relationship among discharge, specific capacity, and drawdown. Under both confined...
Delineating Subsurface Contamination Using Geostatistical and Non-Intrusive Geophysical Methodologies
Electromagnetic (EM) conductivity surveys are becoming a more practiced technique in screening for contamination of soil and groundwater. This non-intrusive geophysical approach detects...
Central Artery/Tunnel (CA/T) Project Environmental Permitting
The Central Artery/Tunnel Project is one of the largest public infrastructure projects in the United States. As such it poses major environmental planning and design challenges. The environmental...
PCE in Dewatering Flows?A Case Study Risk-Based Clean-Up Action Levels
Up to 70 micrograms per liter (?g/L) of tetrachloroethylene (PCE) was detected in dewatering flows associated with a construction project (Project) in the City of Los Angeles. Because...
Searching for Optimal Combinations of Stormwater Detention Basins
Hydrology of urban areas is dominated by two distinct characteristics: (1) a preponderance of impervious surfaces created primarily by pavement and roofs, and (2) the presence of constructed...
The Treatment Train Detention Concept
With the recent concern for nonpoint source pollution impacts to receiving waters, the Village of Saukville, Wisconsin took advantage of state funding grants to conduct a Stormwater Management...
Effective Subsurface Retention/Detention Systems
Stringent environmental regulations and increasing land values have made finding an effective way to manage storm water runoff a high priority for consulting engineers and land developers....
Calibration of Sediment Transport Model for the Upper End of Elephant Butte Reservoir
Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about...
Impacts of NAFTA on Environmental Engineering
This paper addresses recent developments in the environmental sector under the North American Free Trade Agreement (NAFTA). The North American Free Trade Agreement (NAFTA) represents a...
Computing Flood Damage Reduction Accomplishment
Following flood events, the damage reduced by a federal flood damage reduction project must be computed to inform the public and assist officials in making decisions. This paper will describe...
Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...
Artificial Recharge in the Oakes Test Area
The Oakes Test Area (OTA) was developed to evaluate predicted impacts of developing irrigation in the Garrison Diversion Unit in North Dakota. A limited irrigation water supply has forced...
Cropping Systems on the Delmarva Peninsula to Reduce Ground Water Contamination
A total of twelve cropping systems were simulated with the GLEAMS model for nitrate leaching. A precipitation model was developed using a Markov chain model and a gamma distribution for...
Sanata Ana River Project Environmental Compliance with the National Environmental Policy Act (NEPA)
The National Environmental Policy Act(NEPA) was first enacted in. 1969, and became effective as of January 1, 1970. The law was intended to ensure that balanced decision-making occurs...
