Leak detection on dyke by DCOS analysis
The aim of this survey was to define the feasibility of the leak detection on a dyke using passive measurements. A reduced scale dyke has been built in order to control the leaks (their position and outflow).
Active measurements have been performed in order to evaluate the influence of the dyke geometry on the surface wave propagation and their dispersive pattern.
