Water Quality Enhancement Using Subsurface Detention
While underground detention systems have gained wide acceptance in the quantitative treatment of stormwater runoff, the potential exists for substantial water quality improvement. Although...
Simulation of Catchment Response Using RC Network
This paper describes a simple physically-based distributed parameter hydrologic model of catchment response using a network of capacitors and resistors. The effect of topography is modeled...
Optimization Modeling of Complex Surface Water Collection Systems
The New York City (NYC) water supply system is currently being modeled using Linear Programming (LP) optimization techniques. A series of simulations were performed to investigate the...
Resolution of the ACT-ACF Water dispute with a Federal-State Partnership
A Comprehensive Water Resources Study, conducted in partnership with the States of Alabama, Georgia and Florida and the U.S. Army Corps of Engineers (Corps), represents an innovative approach...
Eastern San Joaquin County Groundwater Resource Planning Model Development and Calibration
An Integrated Groundwater Surface Water Model (IGSM) has been developed for the Eastern San Joaquin County in the Central Valley of California to evaluate the future water resources management...
Flood Risk Management: New Concepts for an Objective Negotiation
It has been tested in a real situation like the Bourbre catch ment, a Rhone tributary in the Isere department, not far from Lyon (France). This catchment is 700 km large, the river is...
Identification of Regional (Third Party) Impacts Associated with the Truckee River Operating Agreement
This paper focuses on problems and solutions encountered to identify regional impacts of the Truckee River Operating Agreement (TROA). Two issues influenced the development of a regional...
Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...
Evaluation of System Constant Volume Control
System constant volume control (SCVC) has been developed for optimal control of canal systems. The objective of system constant volume control is to maintain a reference storage (or target...
From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...
High Level Radioactive Waste Management 1996
The proceedings of the Seventh International Conference on High Level Radioactive Waste Management, held on April 29-May 3, 1996, Las Vegas, Nevada, continues a concerted effort to transfer...
Storm-Water Treatment Goes Underground
The field of storm-water management continues to evolve as practitioners gain more experience and knowledge from the successes and failures of the past. While we once treated every site...
Seeking Structural Solutions
A photo essay on the unique work of Santiago Calatrava, a Spanish-born engineer and architect whose bridges and buildings have attracted international attention for their unusual esthetics....
Detecting Leaks Electronically (Available only in Geo/Environmental Engineering Special Issue)
An innovative monitoring system originally developed to detect cyanide leaks at gold mines can now monitor the integrity of geosynthetic liners at municipal- and hazardous-waste landfills...
Columbus Clear Wells
At an average of 8 million gal. each, six new clear wells at the Hap Cremean Water Plant in Columbus, Ohio represent the largest post-tensioned, reinforced concrete noncircular tanks ever...
High Level Radioactive Waste Management 1995
The proceedings of the Sixth Annual International Conference on High Level Radioactive Waste Management, held on April 30-May 5, 1995, Las Vegas, Nevada, continues a concerted effort to...
Beware the Sediment Scare
Your municipal or industrial stormwater facility meets best management practices (BMPs) as outlined by EPA. It is designed to meet requirements under the Clean Water Act and the accompanying...
This paper describes design and analysis efforts to develop a new reconfigurable and collapsible working machine, dubbed Houdini, to remotely clean up hazardous-waste and petroleum storage...
Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...
Storage Tanks: Going Above Ground
Until just a few years ago, the traditional replacement for a leaking underground storage tank was a new UST. But in September 1988, EPA finalized new regulations for UST systems containing...
