Recent Bentthic Foraminifera as a Sedimentation Tool in the Nigerian Coastal Environment
The ratio between the living and total populations of benthic foraminifera has been shown to be useful in determining relative rates of sedimentation in paralic and marine environments....

Implications of Environmental Dynamics for Sustainable Environment and Resources Management Futures in the Niger Delta
The paper examines the implications of environmental dynamics for environmental sustainability and resources management futures. The paper first discusses the concept and characteristics...

Sea-Level Rise in Senegal: Impacts and Responses
The potential impacts and responses of sea-level rise on the coastline of Senegal are analyzed with an emphasis on regional distribution. Impacts include loss of land and the economic...

Patos Lagoon
Patos Lagoon is one of South America's most important lagoonal environments. There is a complex of basins, controlled by the coastal lagoons Mirim and Patos, whose salinity regime is influenced...

Coastal Planning in British Columbia: Problems and Solutions
British Columbia is the most western Canadian province encompassing 27,000 km of deeply incised coastline and myriad islands and waterways. The mix of varied and often conflicting uses...

A Wave-Energy Dissipation Structure for Shore Protection and Beach Generation, Recovery, and Stabilization
WAVEBLOCK a steel reinforced concrete modularized structure designed to dissipate the energy of saline and freshwater waves is described. The modularized structure, which weighs upwards...

Shore Protection Design?A Necessary Evil
Since much shore protection exists and further shore protection will be considered necessary in the future, this paper addresses the need for better design methods to replace the present...

Study on Littoral Protection by Sand-Filled Tube
This study focuses on a new, excellent construction method which excels in both the environmental and scenic aspects. It enables the construction of coastal structures such as jetty, detached...

Preliminary Study on Impacts of Sea Level Rise and Response Strategies in Japan
This paper presents the outline of the study carried out by a Japanese committee on the impacts of and response options to the anticipated sea level rise and climate change induced by...

Design Manual for Artificial Reefs
Artificial reefs are wave-breaking structures artificially constructed from rubble to mimic the wave-control functions of coral reefs. Since these structures are located below sea level,...

Development of Offshore Breakwaters for the Marine Multipurpose Zone Project
Under these circumstances, the ministry of construction of Japan has launched the marine multipurpose zone (MMZ) project,and is promoting the effective use of seashores facing the open...

A Study on Fishing Port Structures in Harmony with Fishery Environment
We have reported on the concept of environmentally productive fishing port structures along the coastline of Japan ('91 LONGBEACH). In this paper we present a field model experiment on...

The Planning and Design of Multipurpose Artificial Barrier Reefs
Multipurpose artificial barrier reef is proposed for the enhancement of fisheries as part of the purpose of entire system of structures in Japan. As part of our planning efforts we are...

Development of the Long Caisson Type Vertical Breakwater
The width of the caisson of a breakwater is calculated based mainly on the wave force expected to act on the caisson. IN this calculation, the assumed wave force is the peak wave force...

Development of the Double Cylinder Caisson Breakwater
A double cylinder caisson breakwater was recently developed to create a calm sea area in deep and high wave open sea areas. In order to confirm some subjects on design method and construction...

Ecolocy-Conscious Submerged Breakwater
A submerged breakwater makes incident rough waves small when their heights exceed a certain level on the site, though the other waves lower than the level are not so much affected by the...

Application of Composite Members to Marine Structures in Japan
Composite structures combined steel plates and reinforced concrete with shear connectors have been applied to port and harbor facilities in Japan since the early 1980s.Composite structures...

Systems for Control of Environmental Conditions in Regional Marine Ecosystem?A Fundamental Study
This study is being executed as a part of the consolidated research carried out by Nihon University. The study is being developed basically by two main research groups; the first group...

IVHS Strategic Planning for Washington State
Implementation of IVHS technologies must be based on a strategic planning approach. The strategic plan must consider regional and statewide needs and should prompt integration of IVHS...

Advanced Highway Control on the Central Artery
The Boston Central Artery/Tunnel project involves highways 190 and 193, in downtown Boston, placing underground 7 miles of four to eight lane tunnels. The project, with 37 lane-miles underground,...
