Dispersion curve inversion

This tutorial shows how to invert a dispersion curve measured for surface waves. It is based on dinverdc module used inside dinver framework.

Getting ready

Start Dinver with Surface Wave Inversion module.

At first glance, the interface might look a little bit messy. If it is the first time you start dinver, you'd better close all windows until having an empty workspace. The various tools will be displayed one by one and explained in this tutorial, in a logical order.

Importing the dispersion curve to fit

• Activate the Target panel in menu Tools.
• Select the Dispersion option. Leave the Misfit weigth and the Min. misfit to their default values, 1 and 0, respectively.
• Click on Set to load the dispersion curve, the Dispersion curve target is displayed.

Load a dispersion curve and fix its freqency sampling:

• Load this dispersion curve. It is a theoretical curve computed using this tutorial.
• Select the fundamental curve (use these tips to identify it).
