Beach Stabilization Using Drains?An Experimental Model Study
The use of the drain concept may be an attractive new tool for beach stabilization because it provides an alternative to hard structures and may enhance beach nourishment practices. Two-dimensional...
Wind Generated Wave Resuspension of Sediment in Old Tampa Bay, Florida
Vertical profiles of velocity and suspended-solids concentration were measured at a scientific instrumentation platform in Old Tampa Bay during the passage of a cold front in March 1990....
Wavelets and Air-Sea Transfer
Newly acquired insight into the mechanism of air-sea momentum transfer has also resolved some long-standing questions on air-sea transfer of gases of low diffusivity. Sharp-crested wavelets...
Multi-Directional Wave Velocity by Piezoelectric Crystals
Piezoelectric ceramics are successfully used to measure velocities of waves propagating through a dry granular material assembly. Several directional shear and compression waves are measured...
Stochastic Wave Models for Seismic Ground Motion
In order to describe the nature of ground motion arising from a propagating seismic wave, a stochastic wave model has been developed here and an efficient technique for digitally generating...
Waves Generated by Recreational Traffic on the Upper Mississippi River System
Vessels of all sizes, from canoes to 15-barge tows, share the Upper Mississippi River System (UMRS), and every vessel interacts with the river by means of its displacement, propulsion,...
Ocean Energy Activities in China
The ocean energy will perform an important action to compensate for energy consumption. In China tidal energy was utilized early, building tidal power plants began from the nineteen fifties....
Water Power Resource Investigations in New Zealand
The New Zealand wave resource is dominated by strong uniform swell incident on its western and southern coasts. Electricorp Production has funded the deployment of a wave rider buoy off...
Progress of Floating Type Wave Power Generator
A floating type wave power generator was improved. It is a Backward Bent Duct Buoy (BBDB) which has an air chamber duct which is bent backwards. It is capable of increasing the peak conversion...
Parallel Computations for Automated Finite Element Modeling
This paper discusses initial efforts to combine an automatic mesh generator and element by element solution approaches to produce efficient parallel computational procedures on adaptively,...
Characteristics of the Roesel Machine Used for Small Scale Hydro/Wind or Sea Wave Electric Power Generation and Storage
An electrical machine with property of synchronous as well as asynchronous characteristics and based on ceramic magnet programming technology by continuous printing of the desired number...
Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...
Evaluation of Tsunami Risk at the Southwest Coast of the Iberian Peninsula
The southwest coast of the Iberian Peninsula has a long history of being affected by tsunami waves. The tsunami risk analysis carried out for this area included the compilation of a catalog...
Tsunamis on the Pacific Coast of the United States
The vulnerability of the Pacific coastal areas to tsunamis is examined. The effects of previous tsunamis generated off the west coast of the United States (local tsunamis) and of remote...
Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...
Advanced Concept for Generation of Waves in Hydraulic Models
This paper describes a new wavemaker for the generation of naturally occurring waves in physical models of coastal areas. Recent research incorporating directional aspects of monochromatic,...
Prototype Wave Power Stations in Norway
The KVAENER multi resonant oscillating wave column (MOWC) power station is both described and discussed. The power station, which is now on-line, is designed to produce 1 MW of peak electrical...
Wave Energy Research in Ireland
Measurements taken at several locations off the Irish coast show that the average power intensity available to Ireland well exceeds 20 kW/m. Several projects have been undertaken in an...
On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...
Capacity Planning of Decentralized Small-Scale Hydro Power Plants
Some simple and efficient models are proposed to determine the optimal capacity and the expected energy generation of a decentralized small-scale hydro plant. Both the supply of an isolated...
