Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
Effects of Streambed Processes on Interaction Between Surface and Groundwater
In open channel systems, the phenomena commonly referred to as 'clogging' is caused by settling of sediment and straining of suspended material as water moves...
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...
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...
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...
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...
Incipient Resuspension of Silt-Clay Sediment
The laboratory study of incipient motion of fine-grained cohesive sediment under oscillatory flow, unidirectional flow and the combined effects of oscillatory and unidirectional flow is...
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...
Analysis of Partially Filled Circular Storm Sewers
The classic design approach uses Manning's formula. Comparisons between analytical results obtained in this manner and the many available experimental results indicate substantial...
