Cohesive sediment transport processes influence the geomorphology and associated ecosystems of estuaries, deltas and continental shelves. Consequently these processes will shape the response of coastal wetlands, deltas and estuaries under the present regime of global sea level change. This session focuses on recent advances in understanding cohesive sediment transport processes. Fundamental challenges include the complex biogeochemical interactions in the bed and the formation, breakup and transport modes of cohesive sediment aggregates and flocs. Furthermore, cohesive sediment transport processes present multifaceted modeling challenges and complex interactions on the character and nature of process to product relations recorded in the sedimentary architecture. Submissions focusing on observational, experimental or modeling of cohesive sediment transport processes are encouraged.
