Scour and Fill Monitoring at Lock and Dam No. 26 (Replacement), Mississippi River
Information gathered during construction of the first stage dam is presented. The information consists of data indicating flows and stages along with data obtained from surveys which monitor...
Sedimentation Study for the Rochester, Minnesota, Flood-Control Project
In a cooperative effort, the U. S. Army Engineer District, St. Paul (NCS), and the Soil Conservation Service (SCS) planned a combined flood-control project. The SCS portion of the project...
Numerical Simulation of the Bed Armoring Process
The stability of a river channel depends to a great extent on sediment characteristics. If the amount of sediment coming into a given reach for some reason becomes less than the river's...
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...
River Basin Management: Role of Hydraulics and Hydrology
One of the major Illinois rivers originates in a neighboring state. The main stem of the river was channelized about 65 years ago, and is considered to be a 'drainage ditch....
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...
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...
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...
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...
