Low-Head Drop Structure Hazards: Modeling of an Abrupt Drop Boat Chute
Low-head drop structures are dangerous for navigational and recreational boating in rivers. In an effort to reduce drowning hazards at low-head river drop structures, a boat chute bypass,...
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....
Effect of Barrier Beach Breaching on Harbor Dynamics and Storm Surges
This paper presents a summary of the flood insurance study, commissioned by the Federal Emergency Management Agency, to determine the 100-year flood elevation for Chatham, a seacoast town...
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...
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...
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...
Longitudinal Channel Response Due to In-Stream Mining
This paper describes the analysis procedure developed for the Arizona Department of Transportation for the estimation of short-term longitudinal channel response due to in-stream mining....
Experimental Study on the Hydraulic Characteristic and Trapping Efficiency of a Vortex Tube Sediment Trap
In this paper, an expression of water extractor ratio of a vortex tube has been obtained according to the principle of energy conservation and transformation; based on the feature of sediment...
3-D Free Surface Flow Modeling by Efficient Finite Element Method
3-D free surface flows in highly irregular boundary configurations are among the most difficult natural phenomena to be simulated by mathematical modeling. Not only the problems of accuracy,...
Flow Transitions Around a Single Large Bed Element
A qualitative description of the characteristics of supercritical-to-subcritical flow transitions due to the presence of a single large bed element (LBE) in a laboratory flume is presented....
Numerical Accuracies in Steady Open Channel Flow
The authors have reviewed the accuracy of the individual terms and formulations of the conservation of energy equation as used within the constraints of steady open channel flow modelling....
Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...
Critical Flow Through Bridge Piers
A physical model study was performed at California State University, Long Beach to investigate the location of critical depth within bridge piers in supercritical lined channels. This...
Hydraulic Modeling of Flow Control Gates
Flow control gates are subject to complex hydrodymanic loadings, which may in many cases only be predicted through investigation on a physical hydraulic model. Scaling of gate models,...
Three-Dimensional Modelling of Recirculation Behind a Groyne
Extensive investigation on the three-dimensional flow patterns behind a groyne have been carried out in a small-scale experiment. A three-dimensional hydrodynamic numerical model is verified...
