Ambrose, R. B.
Numerous three-dimensional hydrodynamic models have been developed in the last two decades. The developers of each model have used their own methods to verify the codes before applying...

Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...

Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...

A Physically-Based Model of Channel Widening
The application of many existing models of river channel morphology is limited by their inability to account for bank erosion and changing channel width through time. This paper outlines...

Theoretically-Derived Regime River Width
The governing equations describing the motion of fluid and non-cohesive sediment particles in alluvial channels are combined to analytically determine the equilibrium surface width of...

Determination of Geometry and Stress Distribution of an Optimal Stable Channel
A numerical model which determines the geometry of a threshold channel was recently developed (Diplas and Vigilar, 1992). This is important in the design of irrigation canals, channelization...

Characterization of Incised Channel Development
A combination of hydraulic and geotechnical techniques have been applied to predict future cross-section morphology in incised channels. The SAM program (Copeland, 1991) computes combinations...

Field Evaluation of the Sediment Transport Model Stream with a Bank Erosion Component
The graded sediment routing and stream bed evolution model STREAM of Borah, Alonso and Prasad was expanded earlier by incorporating a riverbank erosion component of Osman and Thorne. In...

Expansion and Contraction of Powder River Between Moorhead and Broadus, MT: Geomorphic Observations and Numerical Modeling
Sixteen years of annual surveys demonstrate that the channel of Powder River expands at high flows and contracts at low flows. Channel contraction is associated with the formation of benches...

Air Entrainment and Bubble Behavior in Plunge Pools
This study analyzes air entrainment by falling nappes and bubble behavior in plunge pools, using an experimental-analytical-numerical method. The experimental work was done at the Tennessee...

Determination of Sediment Profile for a Dry Flood Control Basin
A modification of the standard delta profile method was used to estimate the sediment profile in a dry flood control basin. Dry flood control basins do not have a normal operating pool...

Luo, Ming
The algebraic stress model of turbulence is employed to calculate the 2-D flow field of the Gongzhui reservoir region. The discharge distribution among the discharging structures is achieved...

Numerical Modeling for Sediment-Pass-Through Operations of Reservoirs
Numerical modeling using the FLUVIAL-12 model was made to determine the feasibility and effectiveness for Sediment-Pass-Through (SPT) operation for Cresta and Rock Creek Reservoirs in...

Reservoir Sediment Removal: Hydrosuction Dredging
Hydrosuction dredging is a relatively little-known method of removing sediment deposits from reservoirs. The method is similar to traditional hydraulic dredging except the difference between...

Stochastic Control With Bounded Sample Paths: An Application to Reservoir Systems
The consideration of at least the first two statistical moments for the storage volumes of a reservoir system is crucial in an analysis aimed at determining the optimal operations policies...

Multi-Reservoir System Simulation Design Using C++ and Object Oriented Programming
Scientists and Engineers intuitively perceive the world as objects with interactions and internal processes. Physicists may view there work as different particles exerting forces on each...

Relation of Unit Gravel Discharge to Mean Velocity
In sand-bed streams, the unit discharge of sand varies approximately with the fifth power of the mean velocity and inversely with the median diameter of the bed sediment. Similar relations...

Flow and Sediment Transport at River Diversions
Flow pattern and sediment transport at diversions are studied. Submerged vanes are shown to be an effective measure for reducing sediment entrainment. Effectiveness of the vanes is evaluated...

Modeling Kinetics of Sediment Removal in Water Columns
Many physical, chemical, and environmental factors govern the rate of cohesive particle sedimentation in aquatic environments. A new information-based model that uses experimental information...

Numerical Modeling of Fluid Mud Transport in Estuaries
The movement of fluid mud has been cited as the most likely cause of rapid sedimentation in channels located in muddy estuaries. A time dependent, two-dimensional laterally-averaged cohesive...
