Colorado River Probable Maximum Floods
Upper limit design rainstorms (ULDRS) were developed for three locations in the Colorado River drainage above Hoover Dam. For each location, the rainfall magnitudes, spatial and temporal...
Unique Design Used for Collapsible Gate
The collapsible gate on the Wausau Dam is unique; there is only one known that is similar in design. The collapsible gate, which looks like an inverted V, was designed by Mead and Hunt...
Double Radial Gates for the Brunau Ice-Retention Weir in Switzerland
During the springtime thaw, the River Sihl, which flows from the south into the city of Zurich, Switzerland, carries large quantities of ice flow. In 1968, to protect the footings of a...

Prefabricated Power Plants, Experience and Prospects
This paper presents the prefabrication concept applied to the Greenup (Greenup Locks and Dam, Ohio River, 72 MW, 1982) and the Sydney A. Murray, Jr. (Old River Control Structures, Vidalia,...
Hydraulic Model Studies?Pak Mun Hydroelectric Project (Thailand)
The paper presents briefly the hydraulic problems related to the project which were successfully solved by the 1 to 100 scale hydraulic model study carried out at the Asian Institute of...
A Rocky Mountain Project Intake/Discharge Channel Flow Simulation Study
A two-dimensional depth-integrated finite element flow model was applied to evaluate pumping and generating flow conditions at the Rocky Mountain Project powerhouse intake/discharge channel....
Sidney A. Murray, Jr. Hydroelectric Power Plant Turbine Hydraulic Design and Testing
This paper describes the project design concept, highlighting the choice of turbine type and capacity. Model testing and analysis of control by downstream gate is an important feature...
Dardanelle Turbines
The Dardanelle turbines located at river mile 205.5 of the McClellan-Kerr Arkansas River Navigation System, are experiencing an unusual amount of wear in the blade trunnion bushings. Oil...
Hydroacoustic Evaluation of Deep and Shallow Spill as a Bypass Mechanism for Downstream Migrating Salmon at Rock Island Dam on the Columbia River
Hydroacoustic data were collected on downstream migrating juvenile salmon (Oncorhynchus spp.) during the springs of 1983 and 1984, and summer 1990 at Rock Island Dam on the Columbia River...
Decision Support for Colorado River Operations
The United States Bureau of Reclamation (Reclamation) uses a simulation model known as the 24-month Study Model for planning monthly and seasonal operations for the Colorado River Basin....
Lysimeter Use in Water Rights Determination
In the Western United States, a water right (the legal right to divert water from a stream) is a property right. The impact a water right has upon a stream is commonly defined through...
Herbicides in Streams: Midwestern United States
Results from a 2-year study of 149 streams geographically distributed across the corn-producing region of 10 midwestern States show that detectable concentrations of herbicides persist...
Operation of Irrigation System and Water Management in Low Lying Paddy Area with Creek Network
Characteristics of the operation and management of irrigation systems were analyzed in the low lying paddy area with creek networks. The irrigation system in Kubota district was chosen...
The Effect of Channelization of R?o Puerto Nuevo on Ground-Water Levels in the San Juan Metropolitan Area, Puerto Rico
Channelization and concrete lining of the Rio Puerto Nuevo and its tributaries in the San Juan Metropolitan area has been proposed to control flooding in low lying areas adjacent to the...
Effect of Choptank Watershed Drainage Project on Suspended Sediment Concentration
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A. conducted a sediment concentration study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of...
Canal Models and You
Unsteady canal simulation models require serious investments of time and personnel. The reasons for deciding to invest in a model, as well as reasons to not invest, are discussed. Canal...
Numerical Methods Used to Model Unsteady Canal Flow
Investigating the response characteristics of irrigation waer supply and distribution systems is essential if a good design is to be developed. Numerical simulation techniques have been...
Source of Atrazine and Desethylatrazine in a River, During Base Flow
A budget of atrazine and desethylatrazine loads was computed for a 116-kilometer reach of the Cedar River in Iowa to determine where these compounds enter the river during base-flow conditions....
