Automation of a River Model
The U. S. Army Engineer Waterways Experiment Station (WES) has used physical models to study sedimentation problems since 1931. With the recent advent of new technology, it was realized...
Secondary Circulation Data Acquisition System
A computerized field data collection system was developed for a project investigating secondary circulation in natural rivers. The instrumentation includes a Commodore mini-computer with...
The Micro vs. Mainframe in Hydrologic Modeling and Forecasting
This paper describes and compares the performance, application, and suitability of a microcomputer as host for the large-scale hydrologic model called SSARR. The SSARR Model is currently...
Finite Element Analysis of Recirculating Flows
The primitive variable and stream-function-vorticity forms of depth averaged viscous fluid flow equations are compared via finite element computations on problems with the same meshes...
Microcomputer Graphics Flood Stationarity Test
Only records that correspond with present river conditions should be used with flood frequency analysis when forecasting. A microcomputer test is discussed which aids in selecting appropriate...
Two Projects Became One
Nontraditional funding and a new law were required before two Cortez, Colo. projects could be combined. Building a new canal and enlarging and lining an existing one to move water in essentially...
Mangrove Creek Dam: Use of Soft Rock for Rockfill
Mangrove Creek Dam is an 80 m high concrete faced rockfill dam (CFRD) completed in 1981. The embankment was constructed largely out of low strength sandstones and siltstones available...
Boondooma Dam
Concrete faced rockfill construction was adopted for the 210 ft (64 m) high Boondooma Dam in Southern Queensland, Australia, after detailed comparison between concrete faced and earth...
Design of Deer Creek Dam
The Deer Creek Dam is proposed to be a concrete face rockfill structure (CFRD) with upstream and downstream slopes nominally 1. 3 horizontal to 1 vertical. The embankment will rise 280...
Segredo Dam: Basic Design Aspects
Segredo dam, located immediately downstream of Foz do Areia in the Iguacu river, Parana, Brazil, is the next concrete face rockfill dam to be built by 'Companhia Paranaense...
The Upstream Zone in Concrete-Face Rockfill Dams
The upstream zone of small rock, the supporting zone for the slab at many recent concrete-face rockfill dams has contained less than 20% of particles smaller than the No. 4 sieve. Such...
Streamflow Losses in the Santa Cruz River, Arizona
The discharge and volume of flow in a peak decrease as the peak moves through an 89-mile (143 km) reach of the Santa Cruz River. An average of three peaks per year flow the length of the...
Current Corps of Engineers Concepts for Roller Compacted Concrete in Dams
Since construction of Willow Creek Dam in 1982, Elk Creek Dam in southwest Oregon is the only Corps of Engineers dam to be constructed using RCC that has passed beyond the planning stage...
River Lock Rehab: A Winter's Tale
Lock & Dam �1 on the Mississippi River between Minneapolis and St. Paul had deteriorated badly but the U.S. Corps of Engineers determined that replacement with a new structure...
New Plant Treats River and Well Water
A new 16 mgd water softening plant at Elgin, Ill. is designed to treat raw water either from the Fox River or deep wells, or in any combination. Flexibility of the chemical feed systems...
Bridge
Named Outstanding Civil Engineering Achievement of the Year, the Luling-Destrehan Bridge across the Mississippi River, twelve miles north of New Orleans, has a 1,222 ft. main span that...
Prefab Power
The Love Hydroelectric Generating Station, owned by the city of Vanceburg, Ohio, was prefabricated in France complete with all components, brought across the Atlantic and towed to Greenup...
Refuse Recycling
The refuse recycling plant at Columbus, Ohio, is a pioneer in burning as fuel a combination of refuse and coal. This hybrid fuel has advantages over burning either alone. One winter in...
Flood Control
The Hamilton and Riemer reservoirs were constructed by excavating pits below grade to receive flood overflows from adjacent streams. The two reservoirs are part of a 52 sq. mile (135 km�)...
River Meandering
The erosion and sedimentation processes associated with river meandering have a profound effect on man's use of rivers and their valleys, as well as the natural environment....
