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...
Characteristic of the Yellow River Delta
The yellow river delta is a most unstable delta in the world. The river burst its lowstream bank 1500 times during the last 3000 years, 26 large shifting of the channel as well. The river...
Classification of Coastal Zone by Multi-Variate Analysis
Coastal zone is characterized by various factors such as natural and socio-economic conditions. The present paper proposes a method to classify the coastal zone into some identical groups...
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 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...
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...
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...
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...
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...
Comprehensive Stormwater Management Planning
Prince William County, Virginia and the Environmental Protection Agency (EPA), Region III, are implementing an interagency, interdisciplinary stormwater management demonstration project....
Effect of Agricultural Drainage on Water Quality in the Mid-Atlantic States
Agricultural drainage development in the form of drainage alone and controlled drainage-subirrigation (CD-SI) has created conflicts with environmental concerns. Most concerns the lack...
Dune Profiles Before and After Storm Events in Coastal Massachusetts
It is well known that short-term changes in dune profiles can have a major effect on the severity of storm damage to coastal areas. In light of this, the standardized methodology developed...
Mathematical Modeling of the Sacramento-San Joaquin Delta
The Sacramento-San Joaquin Delta consists of a complex network of interconnected channels, open bodies of water, dead-end sloughs, export pumps, reservoirs, tide gates and irrigation pumps....
Protecting the Boca Raton Outfall Before and After Hurricane Andrew
A critical factor for the success of an ocean outfall is its ability to remain intact and functional for many decades of service, despite extreme episodes of wave attack and beach erosion....
Relationships Between Flow and Benthic Communities
Current flows can affect directly factors critical to the survival of benthic communities, including the availability of food and nutrients, the chemical quality of water surrounding benthic...
Fluid Mechanics Aspects of Ocean Outfalls
Prediction of the environmental effects of ocean outfalls requires understanding of some complex fluid mechanical phenomena. These include the dynamics of merging plumes in flowing, density-stratified...
Halloween Wave Transformation Near Virginia Coast
The Halloween Northeaster of October 29-31, 1991 generated a unique severe sea. The storm waves propagated through two wave stations which are 87 km apart. The wave spectra of the storm...
Acoustic Doppler Current Profiler for Inlet Current Measurements
A BroadBand Acoustic Doppler Current Profiler (BroadBand ADCP) was used to survey tidal currents at Shinnecock and Moriches Inlets, Long Island, NY. Measurements were made remotely form...
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...
