Should We Use the Open Ocean to Ease Pressure on the Coastal Zone?
This paper proposes a framework for analysis of issues arising from the prospect of deep-ocean dumping of wastes. While it takes no stand on the issues themselves, it examines the motives...

Combating Coastal Pollution in Ghana
Studies conducted along the Gulf of Guinea in Ghana have shown that the coastal environment in some places is polluted. Efforts made to combat this problem have so far not been effective...

Nourishment of San Luis Beach, Galveston Island, TX
It has been proposed that one way of stopping shoreline retreat and protecting the foot of the Galveston Seawall is to nourish the complete length of the beach in front of the Seawall....

Quantification of Net Shore-Drift Rates in Puget Sound and the Strait of Juan de Fuca
The objective in this study was to determine the annual rate of net shore-drift at selected sites within Puget Sound and the Strait of Juan de Fuca. These sites were selected based on...

Inlet Dredging Production as a Function of Sea State
This paper attempts to explain some of the inaccuracies and discrepancies in present methods of measuring dredging volumes and looks at a comparison of measured dredge volumes to natural...

Integrated Disposal Studies in San Francisco Bay
The United States Army Corps of Engineers is studying the accumulation of dredged material at the Alcatraz Disposal Site in San Francisco Bay. Alcatraz was chosen for aquatic disposal...

Sand Bypass System at Oceanside, California
This paper describes the design and development of an experimental sand bypassing and channel maintenance system using jet pumps and fluidizers. The system was developed as a possible...
