full_question: A model of this process includes an ad hoc "spike" term that Drake and Calantoni added to the BBB formula. Another model of this process uses an equation with empirical constants determined by Meyer-Peter and Müller to calculate a dimen- sionless function defined by Hans Albert Einstein. The Rouse number determines the manner in which this process occurs. The Exner equation quantifies the conservation of mass during this process. The threshold at which this process begins can be found by plotting the explicit particle Reynolds number versus the boundary shear stress on a Shields diagram. Saltation is a form of this process in which particles are intermittently removed from the bed load. This process begins with entrainment, ends with settling, and is followed by deposition. For 10 points, name this process in which material that has been created through weathering or erosion travels to a new location.
