Bedforms are structures that are moulded on beds where deposition is taking place. Current-produced bedforms are diverse, and are useful indicators of depositional processes. Most bedforms migrate over the sediment surface. As a result, sediments deposited by bedforms typically show cross-stratification.

CONT

There are three basic classes of "classic," unidirectional bedforms: ripples, dunes and antidunes ... However, moving sediment can generate a variety of different forms depending on the characteristics of the material and its substrate, which ultimately effect transport and bed morphology.
