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...
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...
Sedimentation and Flood Protection for the Lower Yellow River
The Lower Yellow River is known for its disastrous floods in the past. After 4 decades without major floodings, rapid economic and population growths along the River have drew concerns...
The Tidal Inlet Characteristics of a Small California Estuary
The inlet channel of the Russian River estuary in Northern California is subject to frequent closure. The formation of a barrier beach across the inlet channel creates ponding of the river...
Erosion Protection at Hydraulic Structures: A Report From the Task Committee
In 1991 the ASCE Hydraulics Structures Committee formed a task committee on Erosion Protection at Hydraulic Structures. The purpose of the committee is to determine current practices in...
Methods for Prediction of Maximum Scour at Coastal Structures
The most common coast scour-related problems are toe scour at rubble mound structures and vertical seawalls, and scour at the base of piles and horizontal pipelines. Existing scour prediction...
Oxygenation Experiments in the Wave Breaking Zone
Experiments on oxygenation due to waves breaking on a uniformly sloping beach were carried out at the laboratory of Harbor Works, National Technical University of Athens. The influence...
Evaluation of a Proprietary Tape Coating Alternative for the 157 Mile Ivie Pipeline
A two part evaluation of alternative protective coating systems for the 157 mile Ivie pipeline was made. In Part I, an evaluation was made on the suitability of a proprietary tape coating...
Electrochemical Treatment and Protection: Lessons Learned
Corrosion is recognized today as one of the major contributors to the deterioration of steel reinforced concrete structures. Two electrochemical techniques, chloride removal and cathodic...
Modified Graphite Reference Electrodes
The primary aim of this research was to investigate the feasibility of developing an improved, more reproducible, reversible, and highly voltage invariant graphite reference half cell...
Cathodic Protection for Protecting Prestressed Concrete
Due to the good effect of corrosion protection of reinforcing steel bars, even in concrete highly chloride contaminated, cathodic protection for concrete structure now carried out as a...
Whose Risk Is It, Anyway?
Near the now-closed Smuggler Mine in Aspen, Colo. toxic lead sits beneath the grass of area residents' yards. A major portion of soil in the area has lead above the EPA action...
Laboratory Testing of Stone for Rubble Mound Breakwaters: An Evaluation
The quality of the final stone product hinges on the combination of two factors - rock properties and environmental conditions. The environmental conditions associated with production...
Improving Stone Placement Specifications
Thorough preparation of stone placement specifications can go a long way toward keeping projects on track. But developing well-prepared placement specifications is not easy. It requires...
Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
The Assessment of Armourstone for Shoreline Protection
To protect shorelines from erosion, Ontario Hydro is using armourstone at various Generating Stations along the perimeter of the Great Lakes. Armourstone is carefully evaluated prior to...
Service Records of Chicago District Breakwater Stone and How These Relate to Test Results
Breakwater stone production is limited to areas with geologic outcrops capable of producing large rocks. The most reliable breakwater stone is that which exhibits the highest degree of...
