EP41D:
Hydraulic Reconstructions of Sedimentary Deposits and Landforms: Modern and Ancient II


Session ID#: 8254

Session Description:
Sedimentary deposits and landforms reflect the hydraulic conditions that form them. In the case of extreme events (e.g., tsunamis, storms, floods, wind storms, and turbidity currents), accurate interpretation of the hydraulic information contained in ancient features constrains event magnitude and improves assessment of the associated hazard. Additionally, reconstructing recent and ancient environmental conditions on Earth and other planets and moons hinges on our ability to interpret the hydraulic conditions that give rise to landforms and sedimentary deposits formed in different geomorphic and sedimentary environments. In this session we solicit contributions on all aspects of hydraulic reconstructions of modern and ancient deposits and landforms, which may include, but are not limited to modeling, laboratory, field, or remote sensing studies of deposits and landforms created by aeolian, glacial, fluvial, marine and extraterrestrial processes.
