Abstract: This study considers the propagation of a gravity current of a Newtonian (fresh water) or a non-Newtonian liquid (dilute solutions of polyethyleneoxide) with density ƒâ, initial speed U and height h upon the free surface of an ambient liquid (salty water) with density ƒâ+ƒ´ƒâƒn at rest in a basin. The investigation is performed in a three dimensional configuration. With the help of the spatiotemporal diagrams technique, we measured the time evolution of the progress x, the spreading y of the lighter liquid into denser liquid and the mixing layer z. These evolutions have been characterized by scaling laws.
