Rehabilitation of Vertical Thin-Walled Breakwater
Physical hydraulic model tests were conducted to measure wave transmission and force characteristics of a partial vertical thin-walled breakwater. Tests were run for the breakwater in...
Field and Numerical Investigations on Siltation Mechanism in Kumamoto Port
Synthetic investigations on siltation mechanism in Kumamoto Port were carried out by field observations, laboratory tests, and numerical simulations. Natural conditions such as tides,...
Numerical Simulation of Larval Dispersal and Recruitment to Coral Reefs from the Mainstream Water Circulation
Coral reef systems, such as the Great Barrier Reef, Australia, are characterized by populations of fish and invertebrates that, mostly, produce offspring as pelagic larvae. Although some...
Modeling of Salt-Water Intrusion in River Mouth Region
By considering the fresh water and salt water as different phases in a two-phase flow system, a set of equations are given for describing the salt-water intrusion as well as the mixing...
3-D Modelling of Suspended Sediment Transport
A three-dimensional finite difference model has been developed for the numerical simulation of the physical process of horizontal and vertical convection, horizontal and vertical diffusion...
Shore Protection Conflicting Objectives in Decision Making
Shore protection, in an era of rising sea levels and declining sediment budgets, is emerging as a priority item in coastal management. Yet to the traditional conflict between man and nature...
Ocean Wave Propagation up a Narrow Channel
The results of a hydraulic model investigation of ocean wave propagation up a narrow channel are reported. Both monochromatic and random waves were used to study the wave characteristics...
Waves on Coral Reefs
In connection with hydraulic studies for development of a new harbour on the SW-corner of Male Island in the Maldives, the author took an interest in the phenomena of waves on coral reefs....
Chemical Parameters Before a Red Tide Bloom, Gulf of Tehuantepec, Mexico
Gulf of Tehuantepec in the Mexican Pacific is characterized by 'north winds' (Tepehuanos) from October through March. These winds form a upwelling area in front...
Pre-Operational Considerations for Marine Finfish Aquaculture: Site Selection and Allocation in British Columbia
Marine fish farming is a new component in the complex mixture of coastal resource uses in British Columbia. To ensure that the marine finfish aquaculture industry develops within an environmentally...
Numerical Simulation of Alabama's Weeks Bay Estuary
Weeks Bay system models describing water elevation, water circulation, salinity and BOD/DO concentrations are used to investigate two case study scenarios - a dredged ten foot deep boat...
Monitoring the Physical Evolution of Tidal Wetland Restoration Projects
Increased knowledge of the ecology, biology, and physical processes of wetland environments in the last several decades has improved the awareness of the critical role these environments...
Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...
Turbulence Measurements and Parameterizations
Bottom boundary layer and exchange models account for high frequency turbulence via Reynold's averaging and the most advanced closure formulations required by this averaging...
Long Wave Effects in Laboratory Studies of Cross-Shore Transport
A movable bed physical model study was conducted to investigate the influence of trapped low frequency energy on wave transformation and beach profile evolution. Using identical drive...
A Calibrated Longshore Transport Model for Richards Bay
In order to plan maintenance dredging at the Port of Richards Bay, different studies were carried out. These were to determine the extreme dredging rates required in the long term and...
Sand Movement by Wind?Optimising Predictive Power
The aim of the work reported here was to develop a model for the efficient utilisation of standard anemometer data for the prediction of potential sand movement. Accurate aeolian sand...
Suspended Sediment Load at Three Time Scales
Suspended sediment loads were examined at the three time scales of time-series-averaged, wave-by-wave and instantaneous during the wave cycle. Field measurements recorded on a natural...
G6 Coastal Morphodynamics
The contents and the backgrounds of the European coastal modelling programme 'G6 Coastal Morphodynamics', in the framework of the EC-sponsored Marine Science...
Turbulence Modelling of Suspended Sediment in the Surf Zone
A computational model is developed for the prediction of the wave period averaged turbulence structure under a breaking wave. The principal forcing function for the model is the generation...
