Unsteady wave pattern generated by water striders.

Maxence Arutkin, Michael Benzaquen, Thomas Steinmann, Jérôme Casas, Elie Raphaël

We perform an experimental and theoretical study of the wave pattern generated by the leg strokes of the water strider during a propulsion cycle. Using the synthetic Schlieren method we are able to accurately measure the dynamic response of the free surface. In order to meet experimental conditions, we extend B\"uhler's theoretical model (B\"uhler (2007)) to finite depth and show that such an approach is successful at reproducing the experimental findings if one accounts for the nonzero temporal and spatial extension of the rapid propulsion.
