Nearshore wave transformation table (Dutch coast)

Type: Model

Project Phase: Planning and Design

Purpose: Quick assessment of wave parameters for projects affected by wave dynamics

Requirements: basic knowledge on wave modelling/ monitoring

Relevant Software: OpenEarth Viewer (web application) or Matlab (stand-alone tool)

 

About

The Wave Transformation Table is a look-up table to quickly obtain elementary wave parameters (i.e. significant wave height, peak period and direction) nearshore. This information can be relevant to any type of coastal and offshore engineering or marine ecology study in which waves are important, especially if nearby wave measurements are missing, too expensive or too time-consuming. The tool is available both as a web application and as a Matlab application. The look-up table only covers the Holland Coast, but in principle the technique can be applied to nearshore areas anywhere in the world (provided that sufficiently long offshore wave time series are available).

How to Use

The intended users of the Wave Transformation Table are engineers and scientists dealing with nearshore processes. The tool is available as a web application through the OpenEarth Viewer. Users need an internet connection and a Google Chrome browser and can obtain time series of spectral wave parameters with a few button clicks. For more advanced users, the tool is also available as a Matlab application. For proper interpretation of the results it is recommended to have some experience/expertise in the field of wave modeling and/or monitoring.

Practical Applications

The Wave Transformation Table can be used to obtain nearshore wave characteristics for coastal and offshore engineering and marine ecology studies. It requires sufficiently long time series (typically 20 years or longer) of offshore wave conditions to obtain reasonable wave climates in the nearshore.
