MAVS-3WTG Directional Wave and Tide Gauge

Directional Wave and Tide Measurements using the MAVS-3WTG and MWAVES Software

Introduction

Directing marine operations in harbors and coastal waters requires real-time knowledge of the directional wave spectrum and other statistical characteristics of the wave and current velocity field. Real-time and historical wave and tide statistics are also important for coastal engineering projects and for the investigation of coastal processes such as the erosion and deposition of sediments. Williams (NOBSKA) and Terray (WHOI) have shown that these properties can be calculated from integrated MAVS time-series measurements of velocity and pressure. However, the calculation is non-trivial, both numerically and for practical reasons, and care is required in the design of the algorithms. Realistically, that kernel of processing routines also requires a simple operator interface and the presentation of results must be both quantitative and easily interpreted. Marine operations personnel, in particular, must be able to make their decisions in real-time. Nobska developed MWAVES directional wave spectra software to address these needs.
