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,...

IVHS-Organizational Structure and Staffing
Continuing technology advances in IVHS present challenges that many states are unable to meet with their current staffs. Only a few states have recognized the need to plan the need to...

An Integrated Route Assignment and Traffic Simulation System with a Massively Parallel Computing Architecture
This research presents two critical issues in the development of an integrated route assignment and traffic simulation system of ATMS-ATIS applications. The first issue addresses the conceptual...

Lessons from Hurricane Andrew's Effects on Hydraulic Structures
Documentation and description of Andrew's effects on open channels and other hydraulic structures in South Dade County, Florida, are presented, based on observations made during field...

A Computer System to Operate Coastal Structures
The Central and Southern Florida Flood Control Project (C&SF) was designed and built by the U.S. Army Corps of Engineers and is operated and maintained by the South Florida Water...

Hydraulic Modeling of Alluvial Plains (Slopes) and Alluvial Fans Using DAMBRK
The design of hydraulic structures such as bridges on distributary flow areas and alluvial fans require methods that can adequately determine discharges at the structures. Flow conditions...

Non-Intrusive Crack Detection in Clay Landfill Cover Liners
Laboratory and field studies were conducted to demonstrate that the azimuthal variation in electrical resistivity can be used to indicate the presence of cracks in clay systems. Laboratory...

A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...

A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...

Model Structure Validation in Groundwater Modeling
Structure equivalence models (SEM), a new concept in groundwater modeling, have been developed to assist in groundwater planning and management. Using SEM, the engineer is able to satisfy...

Linear Pertubation Model: An Application to Tanzanian Catchments
Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural...

Getting Along: The Geotech and the CM
The opinions of geotechnical engineers are usually respected within a consulting firm, but when such a specialist gets out in the field, he or she is seen as merely part of the backup...
