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,...

A Study of the Water Environment Improvement about Fishing Villages
In recent years water pollution has become a serious problem in anchorage and other sea areas, as a result of residential waste water from hinterland fishing communities of fishing ports,...

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...

Quantitative Assessment of Marine Traffic Environment by Using the Maneuvering Space Concept
In a coastal zone, it frequently becomes important to assess the influence of the constructions upon the marine traffic environment. Marine traffic is a man-machine system, and so not...

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...

A Study of Political Decision Method for Remote Island's Environmental Management?Patterns of Remote Islands and a Political Goal
Remote islands are handicapped in their incomes and living conditions, because they are surrounded by oceans, the area is rather small, and also they are far from economic and cultural...

Aiming at Port and Harbour Technology Mild to Human Beings and the Earth
The ports and harbors bureau of the ministry of transport formulated and announced a long-term port and harbor development policy, ports and harbors toward the twenty-first century aiming...

Change of Estuarine Processes Due to Sea Level Rise and Navigation Channel Improvement
To investigate the relationship between the improvement of navigation channels and the change of estuarine environment under various sea level rise scenarios, numerical study was performed...

Design Hydrographs in Coastal Wetland Watersheds
The use of synthetic unit-hydrographs for hydraulic design in ungaged watersheds has been an accepted practice for over 50 years. In southeastern U.S. coastal regions, which contain extremely...

Can Statistical Methods Help to Forecast Drought?
Relationships have been developed between rainfall in eastern Australia and both southern oscillation (SO) and sea surface temperatures (SSTs), and between rainfall in Ghana, West Africa...

Stochastic Modelling of Mean Monthly Runoffs for Coruh Basin, Turkey
Stochastic models of monthly runoffs for Coruh basin, Turkey are presented. Coruh basin is located on the northeast part of Anatolia near Black Sea. Three gauging stations which have about...

A New Look at the Potential of Hygroscopic Seeding in Summertime Convective Clouds
Hygroscopic seeding was conducted in the sixties and early seventies in the USA, but since then, most cloud seeding efforts have used glaciogenic seeding materials, usually silver iodide...

A Semi-Discrete Element Approach to the River Ice Breakup and Jamming Process
A semi-discrete element approach was developed to simulate the whole river ice breakup and jamming process. In this approach, ice mass is treated as discrete elements, and the movement...

Structural and Ice Effects on Salt Water Marsh Hydrology
This study focussed on a New England salt water marsh in which the construction of two drainage structures (culverts) have significantly affected the marsh hydraulics. The result is the...

Refined Modelling of Water Quality Constituents in a Semi-Enclosed Coastal Wetland Basin
Details are given of the refinements to a numerical model to improve the representation of the advective transport of water quality constituents. The higher order accurate scheme adopted...

Survival of Atlantic Salmon Smolts Bypassed Through Ice-Log Sluices Determined by the HI-Z Turb'N Tag
The HI-Z Turb'N Tag was used to assess injury and mortality incurred by Atlantic Salmon (Salmo salar) smolts bypassed through ice-log sluiceways at two stations. Both sluiceways were similar...

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...

Anti-Icing...The Liquid Answer
In the fall of 1984, Great Salt Lake Minerals and Chemicals Corporation of Ogden, Utah (a major producer of Salt and Allied Chemicals) introduced their 'Alternative Deicers' to Washington...

Getting Ahead of Snow and Ice
Winter maintenance is not the same anymore. New weather forecasting technologies are permitting snow and ice fighters to better predict when unsafe winter weather conditions will occur....

Snow and Ice Control in Japan and United States
Both Japan and the United States experience severe winter conditions that require major resources and large expenditures for maintaining highways. The maritime climate that prevails in...
