The ARC Reefs: Designed Artificial Reef Systems
Results of laboratory tests and preliminary results of field tests indicate materials and designs incorporated in The American Reef Corporation (ARC) designed artificial reef structures...
New Directions in Atlantic Artificial Reef Development
The National Fishing Enhancement Act (PL 98-623) of 1984 placed a new emphasis on the role of artificial reefs in fishery development and management. Subsequently, the growth of marine...
Water Use Zoning: Is It a Solution for Resolving Coastal Water Use Conflicts?
In the last few years, North Carolina's coastal area has witnessed unprecedented growth. This paper focuses on selected conflicts associated with recreational and other economic...
The Washington State Public Access Program: Finding Solutions to the Shortcomings
This paper discusses the problems of providing adequate public access and focuses on many of the solutions which have been found and implemented in Washington State. In 1983, the Shorelands...
Resident Only Moorings: A Sign of the Times Or an Endangered Species?
As the demand for mooring space has increased in various coastal harbors throughout New England, many New England coastal communities have enacted legislation giving either explicit or...
Public Access on Private Property in New York City
The New York City Waterfront Revitalization Program (WRP) was approved by the city's governing body, and the New York State Secretary of State in 1982. The WRP established...
Erosion Control Measures and Beach Restoration Plan at the Niigata West Coast
This paper first presents the process of erosion and the history of control measures at the Niigata west coast. The paper further discusses an epoch-making shore protection and beach restoration...
Massachusetts Marine Lakes Restoration Program (
The Massachusetts Department of Environmental Quality Engineering, Division of Water Pollution Control, administers the state's Clean Lakes and Great Ponds Program. The program,...
Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...
Long Crested Weirs
A method has been developed to integrate and evaluate the head relationship between canal weirs and turnouts. The objective is to minimize flow variations through the turnout and at the...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
Physical Modeling of Contracted Flow
Experiments on steady flow over uniform grass roughness through centered single-opening contractions were conducted in the Flood Plain Simulation Facility at the U. S. Geological Survey's...
Simultaneous Releases from a Stratified Reservoir
The concept of simultaneously, selectively withdrawing water from multiple levels in a thermally, and therefore density, stratified reservoir is presented and its usefulness discussed....
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Riprap Stability on Channel Slide Slopes
The stability of riprap placed on a sloping bank is decreased because one component of gravity tends to displace the rock down the slope. Results of riprap stability tests on sloping banks...
Estimating Average Velocity in Cobble-Bed Channels
A data set obtained from natural channels having D//5//0 less than 64 mm and d/D//5//0 in the range of 3 to 20 is used as a basis for testing equations proposed by Limerinos, Thompson...
Pressure Fluctuations on the Floow of Hydraulic Jumps
This paper presents the results of an experimental investigation regarding the variation of r. m. s. value of pressure fluctuations on the floor of free and forced hydraulic jumps formed...
Plume Underflow Interaction in Natural Enclosures
A preliminary investigation into the feasibility of using a hot-water plume to intercept and entrain a cold underflow is presented. The investigation involved an adaptation of existing...
Open Channel Flow Resistance in Horseshoe Conduits
An experimental study of open channel flow resistance in horseshoe-shaped conduits is reported. The friction factor is shown to increase approximately 20 percent in comparison to values...
Experiments on Culvert Flow
Laboratory experiments are described which were performed on small-scale models of smooth circular culverts of length-to-diameter ratio varying between 13 and 52, and longitudinal downward...
