DESCRIPTION:In this talk I will discuss different wave phenome
 na associated with motion on the surface of water.
  I’ll start with some previous work on waves in Ol
 ympic rowing and how to reduce drag\, either by tu
 ning the shape of the boat\, or by exploiting hyst
 eresis patterns in regions of shallow water. Then 
 I’ll talk about current research within the theme 
 of wave-driven propulsion\, i.e. how thrust can be
  generated from surfing the gradients of a self-ge
 nerated wave-field. This phenomenon occurs across 
 a wide range of scales\, from tiny walking droplet
 s in a vibrating bath\, to jumping up and down on 
 the sides of a canoe to drive it forwards\, also k
 nown as gunwale bobbing.
