3 Getting Started
3.1 General
The purpose of this chapter is to give you a general check list, which you can
use for determination and assessment of wave dynamics in ports, harbours
and coastal areas using the MIKE 21 Boussinesq Wave model.
The work will normally consist of the six tasks listed below:
 Defining and limiting the wave problem
 Collecting data
 Setting up the model
 Calibrating and verifying the model
 Running the production simulations
 Presenting the results
Each of these six tasks are described for a “general wave study” in the follow-
ing sections. For your particular study only some of the tasks might be rele-
vant.
Please note that whenever a word is written in italics it is included as an entry
in the Online Help and in the Reference Manual.
3.2 Defining and Limiting the Wave Problem
3.2.1 Identify the wave problem
When preparing to do a study of e.g. wave disturbance in a harbour, you have
to assess the following before you start to set up the model:
 What are the “wave conditions” under consideration in the “area of inter-
est”?
 What are the “important wave phenomena”? The following phenomena
should be taken into consideration:
– Shoaling
– Refraction
– Diffraction
– Partial reflection/transmission
– Bottom dissipation
– Wave breaking
– Run-up
– Wind-wave generation
– Frequency spreading
