Creatively Cost Sharing a Large Flood Control Dam
The passage of Public Law 99-662 in November of 1986, commonly known as the Water Resources Development Act of 1986, added a new dimension to Federal development of water resource projects....
Sediment Management Challenges of the Red River Waterway Project
The Red River Waterway project consists of channel stabilization and construction of navigation locks and dams to provide a 9 foot minimum depth for a distance of approximately 236 miles,...
The Impact of the Morris Sheppard Dam Experience on Buttress Dam Safety Evaluations
The stability problems encountered at the Morris Sheppard Dam have had an impact upon the Federal Energy Regulatory Commission's (FERC) dam safety program. This paper describes...
Restoration of a Buttress Dam
Inspections of Morris Shepard Dam on the Brazos River in Texas revealed serious defects in the dam and its foundation. Piezometric pressures below the spillway buttresses greatly exceeded...
Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...
Possum Kingdom Lake: The Impact of Releases for Fish and Wildlife
Possum Kingdom Lake is a 570,000 acre-foot reservoir on the Brazos River in Palo Pinto County, Texas, owned and operated by the Brazos River Authority (BRA). In 1985 the BRA applied to...
Montgomery Point Lock and Dam Entrance to the McClellan-Kerr Arkansas River Navigation System
The McClellan-Kerr Arkansas River Navigation System has experienced a steady and positive increase in use. However, in the last 10 years changing conditions along the Mississippi River...
Benefits from Floodplain Management Activities in Relation to Operating South Holston Dam
Floodplain management activities have primarily been directed toward avoiding floodplain siting where practical; where siting is unavoidable, elevating structures, facilities, or equipment...
Flownets by Computer Graphics
A new method of drawing flownets for determining seepage losses in earth dams is developed. The flow and equipotential lines are drawn by modifying W. Kinzelbagh's method....
Sons of Martha: Civil Engineering Readings in Modern Literature
These three stories excerpted from the new book Sons of Martha, compiled by Augustine J. Fredrich and published by ASCE as the first book in a new venture by the Publications Division, introduce the engineer...
Fish Bypass Facilities - Tehama-Colusa Canal
Operation of the canal headworks has proven to be detrimental to migrating fish passing the Red Bluff Diversion Dam. Studies performed for the U.S. Bureau of Reclamation were undertaken...
Environmental Aspects of Water Resources Development
Long-term management of resources requires a comprehensive anlysis of the effects that development and management of one resource may be expected to exert upon other resources. However,...
Numerical Simulation of Mudflows from the Hypothetical Failure of a Debris Blockage Lake Below Mount St. Helens, WA
This paper evaluates the characteristics of mudflow events resulting from the hypothetical breaching of a debris blockage dam using a variety of lake levels and impounded water volumes...
Risk Analysis as a Tool to Determine Spillway Design Capacities
Lyman Dam is an earth and rockfill structure located on the Little Colorado River approximately 11 miles south and upstream of St. Johns, Arizona. Several studies examining the safety...
Estimation of Expected Damages, Indemnification Costs and Joint Probabilities of Dam Failures
This paper describes three methods to evaluate structural options for the rehabilitation of an existing dam using the dollar-denominated risk and capital cost associated with each option...
Conceptual Evaluation of Dam Safety by Instrumentation
The criteria governing the design of dams can frequently be imprecise. One of the most practical methods of evaluating dam safety in the dam safety surveillance programs is to check the...
Maximum Scour Below Dams Caused by Over-Fall Flow
The scour of sediment below a check dam caused by over-fall flow will lead to the destruction of dams. The formation of the scour hole below the dam will lead to shorten the seepage lines,...
Modification to John H. Overton Lock and Dam
The Red River Waterway Project, Mississippi River to Shreveport, Louisiana, will consist of a navigation channel 9 feet (2.7m) deep by 200 feet (61.0m) wide, 5 locks and dams providing...
Innovative Spillway Design
The Lake Alan Henry Dam, near Lubbock, Texas, will consist of an earth filled embankment, a service spillway and an emergency spillway. The service spillway is designed to handle flows...
Scale Effects of Overflow-Oriented Hydraulic Parameters for a High Dam
This paper presents the findings of prototype observation and model verification on the surface velocity, the range of nappe jetting, and the diffusion regime of the discharged flow related...
