Session ID#: 8927
Session Description:
Sediment routing systems carve and construct land- and sea-scapes through erosion, transport and deposition of sediment. Quantifying controls on mass extraction through selective deposition and grain size sorting within sediment transport systems is of paramount importance for predicting geohazards, natural resources, and land/sea-scape evolution. Interactions between fluid, topography and sediment in transport systems subject to steady or changing boundary conditions result in a complex array of local and down-system variability in grain-size. Inverting the resulting stratigraphic record to isolate the key variables can be tremendously challenging. This session will focus on building links between grain size trends, sediment transport dynamics, landscape evolution and basin-scale forcings over diverse spatiotemporal scales. We solicit contributions that use field-based datasets, experimental/ numerical models, and statistical methods to quantify grain-size patterns at a range of scales (from dunes and bars to whole continental margins), and/or temporal changes in grain-size patterns preserved in the stratigraphic record.
