Performance Test of Some Selected Sediment Transport Formulas
Performance of some selected sediment transport formulas was tested using a parameter-sensitivity analysis and a series of numerical experiments with an imaginary channel data. Selection...
River Sediment Discharge Study?San Diego Region
Procedures and general results are presented of a recent study performed to estimate the average annual sediment delivery (sand sizes and larger) from sources discharging to the southern...
Redondo Beach King Harbor Model Studies, California
Redondo Beach King Harbor frequently experiences damage when large winter waves occur in conjunction with high water levels. Damages consist of revetment failure, land erosion, flooding,...
Physical Model Study of Navigation Conditions
This paper describes a physical model study performed to assess the impact of increased flows from a redeveloped hydroelectric generating station on the ability of pleasure boats to navigate...
Model Study to Design a Small Intake
A 1:4 scale model was used to design the make-up water intake structure for Burrillville Combined-Cycle Power Plant, Ocean State Power Project. The objective of the study was to assure...
Hydraulic Modeling of Boating Hazards and Sedimentation?Union Avenue Dam, Denver Colorado
Hydraulic jump type energy dissipators are a hazard to recreational boaters. Many white water boaters have been trapped in 'reverse roller' hydraulic jumps. Numerous...
The Study and Practice of the River Regime Planning and Sediment Management in Gezhouba Project of the Yangtze
Based on the Practice of Gezhouba Project, the first water control project on the mainstem of the Yangtze and the largest hydroproject in China, this paper lays emphasis on importance...
Characteristics of Flow Pressure Pulsation and Similitude Law of Model
As described in this paper, the characteristics of flow pressure pulsation and similitude law of model are derived from experiments on some prototype dam and serial scales models....
Numerical Modeling of Irregular Hydraulic Jumps
In its simplest form a hydraulic jump characterized by an abrupt increase in the water surface elevation from a depth less than the critical depth, Dc,...
Solving Turbulent Flows with Finite Elements
A finite element computer code using the q - r turbulence model is applied to turbulent flow under a sluice gate. The addition and slow removal of artificial diffusion enhances convergence....
Grid-Induced Errors in Depth-Averaged Flow Fields
A computer code called CH2D (Curvilinear Hydrodynamics in Two Dimensions) for computing depth-averaged free-surface flow fields has been used to assess the impact of the rate of change...
Cumulative Impacts Analysis on a Midwest Fluvial System
The US Army Corps of Engineers recently completed an analysis of the cumulative impacts of erosion control structures on the Platte River in Nebraska. This was done in response to concerns...
Hydraulic Geometry of Mississippi Hill Streams
Hydraulic geometry data based on field and office studies are presented for a series of streams in the Black Creek and Long Creek watersheds in the upland hills of Central and Northern...
Sediment Yield and Accumulation in the Cache River
Sediment data collected in the Cache River basin of southern Illinois were used to calculate the sediment yield from tributary streams draining into a significant wetland area. Sediment...
Bank Erosion During the 1988-Flood in the Rumoi River
Observations of the bank erosion were performed in the Rumoi River after the flood in August, 1988. It was found from the detailed research that the pattern of the flood was an important...
The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...
Waves Generated by Recreational Traffic on the Upper Mississippi River System
Vessels of all sizes, from canoes to 15-barge tows, share the Upper Mississippi River System (UMRS), and every vessel interacts with the river by means of its displacement, propulsion,...
Studies on the Physical Effects of Commercial Navigation Traffic in the Upper Mississippi River
Changes in water velocity caused by passage of commercial navigation vessels were measured 180-500 ft (55-152 m) from shore at River Mile (RM) 504.8 in Pool 14 of the upper Mississippi...
Flow Separation Around a Solitary Dike: Eddy Viscosity and Mesh Considerations
The hydronamic model RMA-2V has been verified on a variety of global circulation studies. These studies rarely involved separated flow patterns around sudden expansions or contractions....
Aeration of a Submerged Jet-Flow Gate
Submerged operation of a jet-flow gate requires special treatment of the area downstream from the gate to avoid cavitation damage. The Bureau of Reclamation studied operation of a submerged...
