Abstract

Both erosion and unequal deposition of sediments control the gross morphology of arctic deltas. In addition to normal fluvial erosion, levee morphology in an arctic delta may be significantly modified by wave action, ice abrasion, slumping, solifluction, and thermal degradation of perenially frozen sediment. These processes are analyzed and their effect on levee retreat and rates of aggradation and progradation of slip-off and point bars along shifting channels in the Mackenzie River Delta is described.
