Risk Assessment of Lake Shore Development of Devils Lake, North Dakota
In recent years, the advent of the flood insurance programs has forced developers, financiers, and planners to deal with future high water conditions and associated risks. A reliable method...
Initiation of Density Currents in Diverging Channels: Comparison of Field and Laboratory Data
The transition from free surface channel flow to a submerged density current has been investigated in the laboratory. A set of field data has been collected at a wastewater effluent site....
Submerged Flow in Parshall Flumes
Recent data collected in a 1-foot Parshall flume located in the Bureau of Reclamation's hydraulic laboratory indicate a significant discontinuity in the discharge/submergence...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Federal-State Conflicts & A 12-Mile Territorial Sea
The growing tension between coastal states and the federal government can be lessened by amending the 1953 Submerged Lands Act to give coastal states a 12-mile territorial sea. For equitable...
Beach Preservation by Means of Offshore Submerged Mound of Dredged Materials
The beach - sediment - dispersion- offshore or alongshore under the effect of waves and wave induced currents, and inland by wind action may cause a net deficit in sediment budget which...
State-Federal Gorda Ridge Task Force as a Conflict Resolution Mechanism
In 1983 the Minerals Management Service of the U. S. Department of the Interior proposed leasing of a large submerged area off Oregon and California for polymetallic sulfide mining. The...
Common Priorities for Managing Marine Protected Areas: Results from an International Seminar
In 1986, representatives from 22 countries participated in the International Marine Protected Area Management Seminar. The Seminar provided an opportunity to identify and discuss major...
Scour Prevention at Bridge Piers
Laboratory experiments are described in which attempts are made to eliminate local scour at bridge piers using submerged vanes and pier collar. The submerged vanes direct bed load toward,...
Estimation of Navigation-Dam Discharge in Illinois
Techniques were used to estimate discharge for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, and Starved Rock Dams on the Illinois River in northern...
Vibrations of Submerged Solids in a Vibrating Container
Dynamic forces on a vibrating submerged solid cylinder in both closed and open-top rectangular containers are evaluated. The submerged cylinder is attached to the base of a dynamically-excited...
Submerged Vanes for Sediment Control in Rivers
A procedure is developed for a rational design of a system of submerged vanes for depth control in alluvial-river channels. The vanes are vertical, small-aspect ratio foils installed on...
Development of the Nauvoo Point Plant Beds
In Pool 19, Mississippi River, the accumulation of sediment has resulted in soft-substrate benthic communities or macrophyte beds. Three areas in the downstream 12 miles of the 46. 3 mile...
Deep-Water Platform Solutions for the Navarin Basin
The environmental conditions prevailing in the Navarin Basin may impose limitations on the type and shape of production, storage and loading structures. The magnitude of the wind and wave...
Preliminary Evaluation of Submerged Aquatic Macrophytes in a Pilot-Scale Aquatic Treatment System
A study was done to determine which species of submerged aquatic macrophytes (Elodea nuttallii, Myriophyllum heterophyllum, Ceratophyllum demersum) were suitable candidates for use in...
Hypsometry as a Tool for Calculating Coastal Submergence Rates
A contemporary rise in relative sea level is slowly submerging the outwash plain which lies behind Long Island's barrier beaches. While relative sea level change rates vary...
Bath County Pumped Storage
The Bath County Hydroelectric Pumped Storage Project provides 2,100 Mw of peak power to Virginia Electric & Power Co. and Allegheny Power Co. Called a bargain at $1.6 billion,...
Vortices at Vertical Intakes
This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex...
Pier Review
Upgrading piers to accommodate ships larger than those for which the piers were originally designed is a common problem facing civil engineers. Three case histories illustrate different...
Fluid/Structure Interaction During Seismic Excitation
Hydrodynamic loading and other fluid/structure interaction effects need to be considered in the design of structures which contain, surround, or are submerged in fluids when subject to...
