A Buffered Advection/Dispersion Lake Water Quality Transport Framework For Modeling Lake Gaston Pipeline Intake Water Withdrawal, Lloyd Ashton Gatling Apr 2000

A Buffered Advection/Dispersion Lake Water Quality Transport Framework For Modeling Lake Gaston Pipeline Intake Water Withdrawal, Lloyd Ashton Gatling

Civil & Environmental Engineering Theses & Dissertations

Water quality response to reservoir water withdrawal is investigated in Pea Hill Arm of Lake Gaston, a non-tidal reservoir tributary, where the point of water withdrawal is in an upstream tributary and influences the direction of tributary flow causing longitudinal velocity null flow conditions to occur. The study also focuses on control of withdrawal rate and timing to optimize both quality of water remaining in the tributary and quantity of water that can be safely withdrawn.

Research was conducted assuming steady state conditions and later under spatial and temporal variability experienced in the reservoir with main lake pool elevation fluctuations …

Water as a Public Resource: Emerging Rights and Obligations (Summer Conference, June 1-3)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell, David H. Getches, and Charles F. Wilkinson.

This conference focused on the legal rights associated with a broad range of public uses and interests in water including recreation, fish and wildlife protection, and water quality. Evolving legal areas such as the public trust doctrine, instream flow laws, federal reserved rights, and wetlands protection were discussed.

Water as a Public Resource: Emerging Rights and Obligations considered the extension of the public trust doctrine to areas previously not covered by this concept, as well as developments in …

Western Water Law in Transition (Summer Conference, June 3-5)

Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Jr., Lawrence J. MacDonnell, Richard B. Collins, David H. Getches and Charles F. Wilkinson.

The prior appropriation doctrine has governed the allocation and use of water in the western United States since the 1850s. The shifting nature of water demand is bringing about changes in the traditional legal system. This conference will consider the fundamental principles of the prior appropriation doctrine together with the important new developments in the law now underway throughout the West.

Selecting Non-Point Source Pollution Treatment Practices Using Linear Optimization, John Gardy Garland Iii Apr 1985

Selecting Non-Point Source Pollution Treatment Practices Using Linear Optimization, John Gardy Garland Iii

Civil & Environmental Engineering Theses & Dissertations

This paper provides a case study application of a linear optimization program as a water quality management tool. The optimization program seeks to minimize the cost of nonpoint source pollution control by selecting the best combination of pollution control management practices for Hampton, Virginia. The management practice options are grass swale roadways, porous pavers, ponds, detention basins and fertilizer management education. Management practice selection is limited by constraints on land-use and water quality. Pollutants evaluated are total nitrogen, total phosphorus, suspended solids, fecal coliforms and biochemical oxygen demand (five-day). The value in the water quality constraints for pollution loading on …


Automation Of The Continuous Coagulation Monitor, Dee Mitchell, James J. Oskowis Jan 1974

Automation Of The Continuous Coagulation Monitor, Dee Mitchell, James J. Oskowis

Arkansas Water Resources Center Technical Reports

The development of automation in the past 50 years has paralleled the accelerating growth of today’s vast technological society. Automatic control systems are indispensable extensions of man's brain that enable him to monitor and regulate his complex environment. The principles of automatic control have a wide range of applications and interests in virtually every scientific field. The need for automatic control systems in vital applications of environmental engineering is both real and urgent. Extensive pollution has resulted in unavoidable water re-use and in the inevitable establishment of stringent effluent standards. Both water and wastewater treatment processes have necessarily become more …
