Exercise 0: first step on ww3 wiki and caparmor use

Exercise 1: installing and compiling WW3

Exercise 2: Setting up and running a test case. Example of Lake Victoria

text for "Lake Victoria"

As it happens for anything new, there are conventions that you may find rather bizarre. If you later work with nearshore applications, you may want to be particularly careful about the way the depths are defined. See this page .

Exercise 3: Numerical effects: time stepping

text for "exercise 3"

Exercise 4: regression testing

text for "regression testing" The regtest environment provides an easy way to test many different features of WW3, and its test cases give you a wide variety of input files to get inspiration from.

Exercise 5: grid generation with gridgen

text for "grid generation with gridgen" This gridgen package, developped by A. Chawla at NCEP is based on Matlab. An earlier version was adapted for Octave by A. Sepulveda.

The process of re-defining the mask at the end of the grid generation can use some text-defined polygon or a point-an-click method as done in the following maskmod_click.m
