This video comes from the National Center for Earth-surface Dynamics. Specifically it is part of an an experiment run by Wansuck Kim (now at Univ. of Texas, Austin) and Chris Paola (Univ. of Minnesota) on the effects of faulting on the steering of fluvial systems and the resultant storage of sediment in an evolving tectonically influenced sedimentary basin.

Details of the experiment and its results can be found at:
