Computer Aided Design of Reinforced Concrete
An interactive computer-aided design (CAD) program for the design of reinforced concrete members is herein described. The program, called ECPRS, designs reinforcement and performs all...
Thalweg Disposal: Demonstration of an Alternative
Disposal of dredged material in the main channel, or thalweg, is an alternative disposal option for maintenance dredging. The material dredged from the Upper Mississippi River is clean...
A Methodology for Open-Water Disposal Site Selection
Pascagoula, Mississippi, is the major industrial region in coastal Mississippi. The existing project, completed in 1965, provides for waterborne transportation from the Gulf of Mexico...
Design and Construction - Theodore Ship Channel
Environmental impacts, greater technological capabilities, and improved evaluation techniques make the disposal of large quantities of dredge material more complex and involved. Also,...
Mississippi River Fairview Crossing Test
To improve estimates of shoaling rates in the crossings of a deep draft channel from New Orleans to Baton Rouge, a prototype test was conducted in Fairview Crossing at Mile 116 above Head...
Shoaling Problems and Improvements Sunny Point, North Carolina
The Military Ocean Terminal, Sunny Point (MOTSU), is located on the Cape Fear River, approximately 18 miles downriver from Wilmington, North Carolina. The facility has experienced significant...
Solving Channel Maintenance Problems at Reads Landing, MN
Dredging a sediment trap at the delta of the Chippewa River is being tested as a channel maintenance technique. It's designed to improve the Corps of Engineers predictive...
Dredging-Related Considerations in Navigation Channel Design
In the design of a navigation project, the channel depth, width, and alignment for a given set of navigation requirements are dependent on physical, hydrodynamic, and sedimentological...
Influence of Roughness on Velocity and Dispersion at Low Flow
Dependence of the hydraulic and transport characteristics of low flow on channel roughness is investigated. Empirical expressions are used to estimate roughness coefficient as a function...
High Sediment Concentrations Require High In-Channel/Supply of Sediment
Flows with high sediment concentrations (greater than 10 percent by weight) most commonly occur either as debris flows in steep channels throughout the world, or as hyperconcentrated flows...
Numerical Model of Mississippi River at Lock and Dam 26
Replacement work was initiated in November 1979. The first stage cofferdam constricted about half of the river channel. As a result, the flow velocity at the constriction increased causing...
Numerical Flood Routing for Natural Channels
A numerical model has been developed for simulating the propagation of a flood wave in a natural channel. Using this numerical model, the influence of the factors affecting the motion...
Mechanics of Mudflows
A Bingham model is adopted to study the fluid mechanics of mudflows. Equations for predicting the transition from laminar to turbulent flow in an open channel are formulated and verified...
Higher-Order Methods for Transient Free-Surface Flows
One-dimensional transient free-surface flows in open channels are described by a set of quasi-linear hyperbolic partial differential equations, called the Saint-Venant equations. Numerical...
Water and Sediment Movement in Irrigation Furrows
Water movement in an irrigation furrow is simulated by numerically solving the governing equations of continuity and momentum for unsteady, spacially varied flow in a pervious bed open...
Modeling Multiple Spur Schemes to Control Bank Erosion
A natural consequence of the meandering tendencies characteristic of all streams, is streambank erosion. The problem has taken on particular interest recently, focusing on erosion problems...
Riprap Sizing-Four Methods
A comparison summary is provided for sizing of riprap by four methods: Isbash, Froude, Tractive Force - Logarithmic Velocity Profile (TFL), and Tractive Force - Power Velocity Profile...
Modeling of a Multifunctional Hydraulic Structure
A 1:12 scale Froude model of a hydraulic control structure in the Rochester Combined Sewer Overflow Abatement Program (RCSOAP) was constructed and tested to optimize the design requirements...
Controlling River Ice to Alleviate Ice Jam Flooding
Many communities affected by ice jam flooding have accepted the event as unpreventable. Others have approached their problem as one of open channel flow and implemented standard projects...
Salmon River Ice Jams
The ice conditions on the river during the freeze-up period and the simple analytical model used to predict the advance of the ice cover leading edge are documented. Ice cover thicknesses...
