This project is being installed at the Dry Falls Dam, Coulee City, Washington, adjacent to the Main Canal Headworks which controls the irrigation releases to the Columbia Basin Project....
The Paerau Gorge Multipurpose Scheme
The Paerau Gorge Power Scheme is part of a multipurpose scheme supplying irrigation water and electricity to the Central Otago region of the South Island of New Zealand. This paper describes...
Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...
Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...
Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
Rapid Filling of Reservoirs
The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels,...
An Overview of Hoover Dam Tunnel Spillway Damage
