Implementing a National Wave Monitoring Network?Some Lessons and Plans
Most environmental problems involve a chemical and/or biological component and a physical processes component. A holistic approach must consider both components and the way they interact....
The TMA Wave-Energy Constraint and Cohesive Shore-Profile Shapes
A relation by Andreanov between wave-energy loss and nearshore slope, when combined with the TMA wave-energy constraint, is shown to closely approximate the classical Bruun/Dean shape....
Design and Testing of the NDBC Wave Processing Module
The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and...
Wave Attenuation at the Mobile Stable Berm
This paper describes work examining the ability of submerged berms to `filter' certain erosive wave energy while allowing accretionary type waves to pass unhindered. Analysis of wave data...
