Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...
An Investigation of the Alcatraz Disposal Site
The Alcatraz dredged material disposal site in San Francisco Bay is a dispersive site that is not intended to accumulate disposed sediment. However, the recent discovery of shoaling at...
Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...
Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...
Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...
Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...
Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...
Methods for Specification and Verification of Hydraulic Design in a Turnkey Construction Contract
The project site is at the Hannibal Locks and Dam at New Martinsville, West Virginia. The existing project, a Corps of Engineers' (Corps) facility built in the 60's...
A Large-Scale Groundwater Transport and Dispersion Test: The First 1000 Days
TVA is conducting a large-scale field experiment to quantify the groundwater transport and dispersion of leachates from solid disposal facilities. This project is an integral part of the...
Contaminant Transport from an Array of Sources
The authors show analytic solutions to the problem of contaminant dispersion from an array of point sources in a waste disposal site. These solutions are for waste sources in a fluid-saturated...
Real Time Modeling to Meet Flow Requirements at a Fossil Steam Plant
A real time modeling system has been developed to schedule hydropower operations in order to comply with discharge permit requirements at a downstream fossil steam plant. The modeling...
U.S. Bureau of Reclamation: How Irrigation Projects are Sized
The objective of this study was to review the methods presently used by the United States Department of Interior, Bureau of Reclamation (Bureau) to estimate the water requirements for...
Reclaiming Wastewater in Phoenix, Arizona
This paper examines the role of wastewater effluent reuse in the future water resource management of the City of Phoenix. The paper seeks to explain why a proposal to renovate effluent...
The Reclaimed Water Delivery System and Reuse Program for Tucson, Arizona
The City of Tucson has implemented a reclaimed water reuse program in a community-wide effort to preserve high quality groundwater for potable and other priority uses. Presently, the system...
The Lubbock, Texas, Land Treatment System
The land treatment system at Lubbock, Texas provides an excellent model for studying the response of a system to growth. It also provides insights and justification for current criteria...
Utilization of Geographic Information Systems Technology in the Assessment of Regional Ground-Water Quality
The U. S. Geological Survey (USGS) in cooperation with the U. S. Environmental Protection Agency Office of Pesticide Programs and several State agencies in Oregon has prepared a digital...
Selenium Removal?Can We Afford It?
The process of biologically removing the element selenium from agricultural drainage water is discussed and an economic evaluation of the process is presented. If by-products can be recovered,...
Agricultural Drainage Water?How Should It be Regulated?
This paper discusses the existing framework of California liquid waste disposal law, the obstacles presented by these and other laws pertaining to agricultural drainage water disposal...
An Overview of Factors Affecting Land Application of Food Processing Wastes
The food processing industry can use slow rate, rapid infiltration or overland flow systems. Slow rate systems are the most common method used for land application. The limiting design...
Winery Wastewater Land Application
Winery wastewater is characterized by low pH, relatively high BOD, and a low nutrient content. Land application using rapid infiltration basins has been practiced successfully at a number...
