    Title : Lagrangian drift by experiments in water waves at finite depth
    Abstract : 
         Laboratory experiments illustrate the particle motion in water waves, 
       the Lagranganian period and drift, obtain that the excess period and drift velocity 
       are equal, exhibit strong shear in the viscous boundary layers at the bottom and 
       below the surface, and experiments and second order and fully nonlinear models agree 
       within the core of the fluid.
