Streamflow Losses in the Santa Cruz River, Arizona
The discharge and volume of flow in a peak decrease as the peak moves through an 89-mile (143 km) reach of the Santa Cruz River. An average of three peaks per year flow the length of the...
A Freeway Simulation Program for Microcomputers
An interactive, menu driven macroscopic freeway simulation program with graphic capabilities is presented in this paper. In addition to the employment of personal computers the program...
TRANSYT 7F Applications on a Microcomputer
This paper describes the results of work undertaken by Michigan State University Civil Engineering graduate students as part of two separate class projects. Significant support was provided...
Pipeline Hydraulic Transient and Leak Detection Analysis
Liquid and gas pipelines cannot be properly designed with consideration of steady flow analysis techniques alone due to the possibility of pipeline failure resulting from uncontrolled...
Advances in CAD for Structural Engineers
In the 1980's Computer-Aided Design (CAD) will offer the structural engineer an opportunity to improve his work. Decreases in the cost of equipment and improvements in computer-aided...
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...
Turbidity Generated by a Model Cutterhead Dredge
The study of turbidity generation indicates that, in general, turbidity increases with an increase in the cutter speed and an increase in the cutter swing velocity. A silt curtain deployed...
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...
Sediment Resuspension from Dredging Activities
Dredges are a logical choice for removing contaminated sediments from our Nation's waterways. Historically, the dredging industry has emphasized increased production in an...
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...
Buoyant Jet Solution with Synthetic Entrainment Function
A synthetic entrainment function is proposed for buoyant jets discharged at an arbitrary angle into otherwise quiescent ambient fluids. The entrainment function consists of two separate...
Effects of High Sediment Concentrations on Velocity and Sediment Distributions
Several classifications are required to describe sediment-transporting flow. The flow may be turbulent or laminar, Newtonian or non-Newtonian, and may also have a uniform or nonuniform...
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...
Flow Parameters of Fluid Mud
A set of small-scale, high-resolution velocity and stress sensors based on rugged metal-clad hot wires and epoxy-encapsulated hot films is to be evaluated for its performance characteristics...
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...
