Water and Sediment Movement in Irrigation Furrows
Water movement in an irrigation furrow is simulated by numerically solving the governing equations of continuity and momentum for unsteady, spacially varied flow in a pervious bed open...
Intake-Shoaling and Pump-Vibration Problems
Iowa Generation's Council Bluffs Unit 3 circulating water-intake structure has experienced two major problems: (1) formation of sand bars in front of the trash racks during...
Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Streamflow Measurement and Analysis for Northwest Rangelands
Watershed hydrologic and sedimentation investigations on the Reynolds Creek Experimental Watershed in southwest Idaho were initiated in 1960. Major objectives of the watershed research...
Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...
Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...
Artificially Varied Flow: River System Management
Some of the major water quality problems are heat, color, organic sediment, and total dissolved solids. To dilute these and other pollutants, substantial augmentation of flows for water...
LTER and Management of the Upper Mississippi River
The Upper Mississippi River is managed for multiple use by two federal agencies and five states. System management objectives include commercial navigation, commercial fisheries, minimum...
Effects of Resource Development on Water Quality in the Big South Fork National River and Recreation Area, Tennessee and Kentucky
The South Fork Cumberland River begins in Tennessee at the confluence of the New River and Clear Fork. Strip mining for coal in the New River basin has been ongoing for decades with little...
Nebraska's Shrinking Platte River Channel: Hydrologic Aspects and Implications
Biologists have proposed two hypotheses to explain recent channel narrowing and vegetative growth in flood plain habitat areas along the Platte River in Nebraska. One group contends, without...
Forecasting and Warning for Mt. St. Helens Streams
The eruption of Mt. St. Helens in southern Washington on May 18, 1980, created great devastation both by the blast itself and by mudflows generated by melting snow and ice. Several hydrologic...
Alternative Layouts for Hydro Headrace Tunnels
The recent development of tunnel boring machines capable of excavating hard rock at virtually any grade together with the Norwegian experience in compressed air surge tanks provides the...
Sedimentation in Small Hydropower Reservoirs
Small-scale hydropower projects, which usually include reservoirs of limited size, may inherently incorporate severe sedimentation problems. The ratio of reservoir volume to sediment inflow...
Walden Hydroelectric Power Project
The Wallkill River at Walden, New York, produced hydroelectric power from 1909 to 1966. Using turbines dating back to the original hydroelectric development, the Walden hydroelectric station...
Research in Hydraulics at California Institute of Technology
Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...
Current Research in Hydraulics at the Corps of Engineers Waterways Experiment Station
Ongoing activities in hydraulics research at the U. S. Army Engineer Waterways Experiment Station are described. The various areas in which research is under way are enumerated. Activities...
Sedimentation Consolidation Models?Predictions and Validation
In very soft sediments, questions have arisen concerning the capability of standard computational techniques used to implement calculations. The problems mainly lie in the manner in which...
Guidelines for the Seismic Design of Oil and Gas Pipeline Systems
Current knowledge on the practice of earthquake engineering for oil and gas pipeline systems is presented. Such systems typically consist of buried oil, gas, or product pipelines and aboveground...
A Standard for the Measurement of Oxygen Transfer in Clean Water
This standard was developed to measure the rate of oxygen transfer from diffused gas and mechanical oxygenation devices to water. The standard is applicable to laboratory scale oxygenation...
Measurement of Hydrographic Parameters in Large Sand-Bed Streams from Boats
This report concentrates on the state-of-the-art in the field documentation of the existing channel geometry, plus the concurrent stream flow and sediment transport characteristics, prevailing...
