Water for Resource Development
The primary goal of these proceedings is to provide an awareness of the many areas of resource development in which hydraulic engineering plays a key role. The papers cover a variety of...

Infrastructure: Money and Methods
State and local governments have started to cope with their infrastructure problems by passing bond issues, establishing infrastructure banks to centralize resources and decision making,...

Dredging Developments in the Canadian Arctic
The use of dredges in the Canadian Arctic in connection with oil exploration programmes has lead to the adaptation of existing and adoption of new techniques. Further development is required...

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,...

Selection of Dredged Material Disposal Sites
Federal and state legislation regulating dredging of navigation channels along Maryland's Eastern Shore requires that local governing bodies provide the dredged material disposal...

Placing of Impermeable Underwater Membranes
An impermeable underwater membrane has been applied successfully in the construction of a lowered road section in the Netherlands. In this paper the construction technique is discussed...

Dredged Material Disposal Modeling - Chesapeake Bay
A plan to deepen the approach channels to Baltimore Harbor from 42 feet to 50 feet involves in part the overboard disposal of about 9. 5 million cubic yards of dredged material in the...

An Offshore Mound Constructed of Dredged Material
The concept of using dredged material to intentionally construct an underwater mound was tested and confirmed at the Dam Neck Disposal Site, 4 miles offshore Virginia Beach, Virginia....

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...

Dredging as a Remedial Method for a Superfund Site
Remedial action at the Commencement Bay Nearshore/Tideflats Superfund Site, in the State of Washington, is expected to include dredging and disposal of contaminated sediments located in...

Fundamentals of Agitation Dredging
The definition and basic principles of agitation dredging are discussed. Equipment for agitation dredging is categorized. The principles of operation, advantages, and disadvantages of...

Improved Techniques for Removal of Sediments Contaminated with Hazardous Materials
Realizing the need to improve the capabilities of response personnel in dealing with cleanup operations involving contaminated sediments, the U. S. Coast Guard and the U. S. Environmental...

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...

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 Simulation of the Bed Armoring Process
The stability of a river channel depends to a great extent on sediment characteristics. If the amount of sediment coming into a given reach for some reason becomes less than the river's...

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...

Boundary Element Analysis of Flow in Heterogenous Porous Media
The boundary integral equation method (BIEM) is an efficient numerical method which has been applied to a wide variety of engineering problems governed by a partial differential equation...

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...

Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...

Numerical Modeling of Flow in Hydropower Intakes
To reduce high mortality of downstream migrating juvenile salmon at hydraulic turbines, traveling screens are used to guide the juveniles into a bypass channel for safe passage. However,...
