Shows, in real time, two unconfined debris flows as seen from above. The mixtures of material, slope and volumes are identical, except in the first case the flow is subaerial and in the second case the flow is under water. Coal lines on the surface shows spreading of flow as it enters the unconfined part of the tank.
Note: under water the flow head hydroplanes and detaches from the body of the flow as a cohesive block.
