Fine-grained sedimentary systems: sediment transport dynamics, depositional patterns, morphologic expressions, and climate impact
Fine-grained sedimentary systems: sediment transport dynamics, depositional patterns, morphologic expressions, and climate impact
Session ID#: 247363
Session Description:
Fine-grained sediments comprise non-cohesive sands and cohesive clays, silts, and biopolymers; they abound in many depositional settings, including fluvial deltaic, coastal, shallow and deep marine, subglacial environments, as well as pyroclastic, lahars, and debris flows. Fine-grained sediments can alter fluid properties, dampen turbulence and wave spectra, generate hindered particle interactions, induce flocculation, as well as inhibit erosion and hyporheic flow. The resulting complex sediment-fluid interactions alter tidal currents, internal waves, and tsunami flows. Such interactions also affect large-scale morphologic expressions and depositional patterns that are reflected in the stratigraphic record. Furthermore, fine-grained sediments often harbor biota, which produce biopolymers, and adsorb contaminants and organic matter; such interactions further evolve sediment properties and play a critical role in water quality and the global carbon cycle. This session seeks field- and laboratory-based studies, numerical modeling, and theoretical contributions exploring fine-grained sedimentary systems - from their dynamics to their deposits.
