Coarse Sediment Transport and the Maintenance of Fish Habitat in the Upper Colorado River
An analysis of the relation between discharge and boundary shear stress is presented for an alluvial reach of the Colorado River near Grand Junction, CO. The analysis indicates that the...

Palaeohydraulic reconstruction of floods in upland UK bedrock streams: progress, problems and prospects
Palaeoflood evidence from five small upland Pennine catchments in the UK is used with the HEC-2 flow routine to simulate Holocene peak discharges. Even allowing for uncertainty, sensitivity...

Relation Between Largest Known Flood Discharge and Elevation in Montana
Previous studies relating unit discharge to elevation indicated that large floods in the Rocky Mountains may be limited by elevation. However, high-elevation data are sparse in Montana...

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...

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...

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...

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...

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...

Discharge-Frequency Relationships in Distributary Flow Systems
The paper describes discharge-frequency relationships in distributary flow systems. The stream network that makes up the flow system is described in terms of how the various stream segments...

Comparison of Infiltration Equations Using Flooding Infiltrometer Data
Based on three flooding infiltrometer tests, 27 hydrographs produced by HEC-1 were used to compare peak discharge, time to peak, and storm runoff volume using three infiltration functions....

Evaluating an Autoregressive Model for Stream Flow Forecasting
Daily stream discharge generated by an Autoregressive Model is helpful in the design and risk assessment of temporary riverine construction projects. This case study uses actual daily...
