Some Benefits of Grid by Number Sampling
Describing the overall sediment composition of gravel-bed river reaches and depositional bars is a difficult problem due to spatial variations in the sediment size. Past research has focused...

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...

Historic-Flood Evaluation and Research Needs in Mountainous Areas
An evaluation of historic flood estimates in mountainous areas in Colorado was made to assess their accuracy. The purpose of this evaluation is to enhance awareness of the need to assess...

3D model verification for a groyne and harbor experiment
A discussion of 3D model verification and calibration based on measurements in a flume is carried out for different test cases (groyne, harbor). The measurement data is available for public...

Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...

Velocity Control Rings for RC Pipe on Steep Slopes
This paper discusses the use of internal concrete rings to reduce velocity and concrete erosion for reinforced concrete pipes on steep slopes in the Southern California area....

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...

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...

Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...

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...

Management of Sediments on the Red River Waterway Project
The Red River is a large alluvial river system with the lower 280 miles currently being developed for shallow draft navigation. The navigation project entails construction of five locks...

An Improved Design of Excluding Sediment into River Intake Structures
The function of excluding sediment into river intake structures is usually achieved by the device of sluice ways. Although many sluice ways have been constructed and many formulas are...

Why Design Storm Methods Have Become Unethical
This paper discriminates between continuous and event modelling, and describes some dimensions of ethical design for sustainable ecosystems. Arguments are presented that event modelling...

Combined Stormwater Drainage and Treatment
Due to continuing public concern regarding environmental protection for the nation's waterways, new and more stringent water quality control regulations have been developed. This is most...

Flow and Chloride Transport in the Tidal Hudson River, NY
A one-dimensional dynamic-flow model and a one-dimensional solute-transport model were used to evaluate the effects of hypothetical public-supply water withdrawals on saltwater intrusion...

Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...

Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...

Malaysia's Twins: High-Rise, High Strength
U.S. firms, following the market for new skyscrapers to Asia, are involved in design and construction of twin office towers in the commercial heart of Kuala Lumpur, Malaysia that will...
