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...
Application of a Density-Dependent Flow and Transport Model to a Coastal Aquifer System
A three-dimensional density-dependent groundwater flow and solute transport model for a coastal region in east-central Florida is presented. The model covers an area of approximately 2900...
Density Fluctuations and Use of the Krypton Hygrometer in Surface Flux Measurements
The magnitude of the of the Webb et al. (1980) density corrections on water vapor fluxes due to the flux of sensible heat is examined in terms of the Bowen ratio. The correction due to...
Measuring Soil Bulk Density Profiles with a Single Probe Gamma Density Gauge
Calibrating neutron depth gauges for measuring soil water content profiles requires soil bulk density data. In this study, the feasibility of using a single probe gamma density gauge to...
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...
Density Currents in Pollutant Transport and Mixing
A buoyant spreading model for the current-advected plume is formulated including several distinct mechanisms: convective spreading, interfacial friction spreading, entrainment at the density...
Criticality of Density Intrusions
Previous analyses of density intrusions indicates that a steady interface cannot be maintained if the front propagates at a speed greater than that of long interfacial waves. Supercritical...
A Model for Vertical Transport at a Sheared Density Interface
A physically based model for vertical mixing and transport at a sheared density interface is presented, based on high-resolution measurements from laboratory experiments. It is found that...
Mixing Characteristics of a Transitional Stratified Two-Layer Flow
Small scale structures in a stably stratified two-layer flow are investigated. The flow configuration has the initial velocity interface displaced with respect to the density interface....
