Process geomorphologists are charged with unraveling the mysteries of landform evolution staged over temporal scales that extend from clay platelets to continental plates. With due acknowledgment of a host of exogenetic forces, such as tectonism and climate, that provide the framework for landform evolution, the most fundamental aspect of process geomorphology is the entrainment, transport, and deposition of sediments. Without a means of moving earth-surface materials, landforms would evolve only by contortion.
Sediment-transporting processes invariably involve fluids. Usually they are moving - such as air, water, and ice that initiate and facilitate motion - but ...
