Incremental Damage Assessment (IDA) For Lake Darling Dam
An Incremental Damage Assessment (IDA) has been completed for Lake Darling Dam, located on the Souris River, near Minot, North Dakota [1]. The IDA has indicated that a reduction in flood...
Peak Outflow From a Breached Embankment Dam
A relation for rapidly predicting the peak outflow rate from a breached embankment dam has been presented. The prediction equation is based on reliable data from 19 embankment dam failures...
Empirical Methods in the Design of Ground-Water Quality Monitoring Strategies
Ground-water quality monitoring strategies are designed for environments ranging from the complex to the very simple. Complexity is characterized by socio-economic, public health, and...
Application of Hydrodynamic and Water Quality Models at a Superfund Site in Montana
The water quality model applied to the site is the EPA-supported hydrodynamic and water quality model WASP4 with a modification to enable it to better simulate riverine systems. To provide...
Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...
Probabilities of Hydrologic Extremes and Risk Analysis
Extreme floods of very low probabilities, e.g., 10-6 and 10-7, are estimated using data on annual flood peaks...
Risk-Cost Principles for Dam Safety Analysis
The purpose of this paper is to present the principles and issues of risk-cost analysis as they have evolved in the evaluation of dam safety improvements. The paper also reviews some results...
Extreme Flood Probability Estimates in Practice
Selecting the safety design flood for a dam or siting structures where flooding would cause severe social or economic disruption requires balancing the likelihood and consequences of failure...
The Estimation of Extreme Floods in Brazil
In Brazil, the design flood of a large dam is calculated using either the Probable Maximum Flood criteria or the 10,000-year Flood. Recently a Guidebook has been written to help Brazilian...
Impact of Risk-Based Analysis on Hydrologic Design Practices
This paper provides a brief review of the current hydrologic design practices of the U.S. Army Corps of Engineers (USACOE) for safety inspection of dams and the current hydrologic design...
Hydraulic Design of Mud Mountain Dam Outlet Works Modifications
Mud Mountain Dam is a single-purpose flood control project located on the White River in western Washington State. The existing flood control outlet works consist of an upstream controlled...
Seven Oaks Dam Outlet Works Design
The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps'...
Design and Performance of Diversion Gates at Peace Canyon Dam
During construction of Peace Canyon Dam, river diversion was accomplished using a combination of cofferdams and temporary diversion conduits through the partially completed dam. Inlet...
Real-Time Water Control Plan for a Flood Control Reservoir
A reservoir operation plan is prepared for a single-purpose flood control reservoir. Real-time precipitation data recorded at the dam is utilized to control the reservoir gate operations....
Risk Assessment of System of Dams
The application of risk assessment to a series of dams on a river is presented here. A general discussion of the basic principles of risk assessment approach to dam engineering is given...
Physical Modeling of Major Cutoffs
In 1987, a model study of Lock and Dam No.4 on the Red River in Louisiana required two major cutoffs and a lock and dam to be modeled. Although the Waterways Experiment Station has modeled...
Deposition at a New Dam Near Mount St. Helens
A sediment retention structure (SRS) is being constructed on the North Fork Toutle River in the state of Washington to trap sediments eroding off the 1980 Mount St. Helens debris avalanche....
The Tides Effects on the Dam Break Flood Wave
The accuracy of water level predictions downstream of the dam is dependent upon the breach evaluation, the correct estimation of the roughness coefficients and when the flood wave reaches...
Status of Hydropower Development at Corps of Engineers Dams
The Corps of Engineers is the largest single supplier of hydroelectric power in the United States with 74 projects and an installed capacity of 20,839 MW. In addition, 33 Corps projects...
Rule Curve Operation at Terzaghi Dam to Pass the Probable Maximum Flood
Terzaghi dam is located on the Bridge River, a tributary of the Fraser River. The spillway was originally designed for the 1000-year flood. Probable Maximum Flood (PMF) studies completed...
