transport
means by which geological features move over time
saltation
sediment transport process, moves grains across the bottom by bouncing or hopping.The actual current carries the sediment load in traction and saltation flows,whereas downslope movement under the force of gravity carries the sediment in gravity flows
traction
geologic process whereby a current transports sand grains and larger clasts by rolling or sliding along the bottom. Thus, the grains and clasts interact with the substratum during transport
