Effects of Fines in Gravel Bed Streams Behavior
A model-gravel bed stream is studied in the laboratory. Flow visualization of bedload motion correlates with bursting phenomena near the bed. The bedload variation as a result of the addition...
Movement of Tractive Sediment from Disturbed Lands
The Smoky Creek basin of the coal area of northeastern Tennessee shows extensive evidence of tractive movement of coarse sediment from mined tributary basins into the main channel. Coal-rich...
Numerical Model of Mississippi River at Lock and Dam 26
Replacement work was initiated in November 1979. The first stage cofferdam constricted about half of the river channel. As a result, the flow velocity at the constriction increased causing...
Incipient Resuspension of Silt-Clay Sediment
The laboratory study of incipient motion of fine-grained cohesive sediment under oscillatory flow, unidirectional flow and the combined effects of oscillatory and unidirectional flow is...
Reliability Analysis as Reflected from the Fourth International Symposium on Stochastic Hydraulics
Reliability analysis is perhaps one of the most practically important branches of the general field of stochastic hydraulics. Its potential applications include quantitative evaluation...
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...
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...
Stability of Method of Characteristics
For the analysis of waterhammer, the first-order accurate method of characteristics (MOC) has been widely used for which Courant condition for stability has been developed neglecting the...
Instruments Detect Dam Movement During Construction
Recent attention has been given to retrofitting electrical generation facilities at existing dams. Maintaining a safe structure during construction, and accomplishing this within a budget...
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...
Information Retrieval Sources and Availability in Hydraulics
There is a very general unawareness of information available on hydraulic studies, application of these studies and import for other projects, and results of new project design methods....
Fisheries Engineering Program at Washington State University
Problems associated with the interrelationships of instream hydraulic structures, and migratory and resident fish, are in need of better analysis and design. This improvement can be realized...
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...
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...
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...
A Systems Approach to the Assessment of Water Supply, Treatment, Storage and Distribution Systems
To focus on the needs of a system at present and in the future and to foresee potential problem areas prior to their occurrence, it is advisable for the management of a water utility to...
Current Hydraulics Research at the Iowa Institute of Hydraulic Research
The Iowa Institute of Hydraulic Research is engaged in fundamental and applied research on a broad range of fluid mechanics and hydraulics problems. The history and organization of the...
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 Hydraulic Research in the Ralph M. Parsons Laboratory at M.I.T.
A brief description of the laboratory is given. The staff, researchers, funding and student participation is described. A partial listing of research programs is outlined....
