EP54B:
Morphodynamics of Fluvial, Aeolian, Hillslope, and Coastal Environments Characterized Using High-Resolution Topography and Bathymetry II


Session ID#: 7901

Session Description:
Description: Advances in high-resolution topographic and bathymetric measurement tools, along with novel methods for quantifying morphologic and sedimentary change using repeat survey data, have led to a refined understanding of morphodynamic processes at Earth’s surface. These high-resolution data present numerous procedural, computational, and analytical challenges. This session will explore avenues by which high-resolution data (using structure from motion, terrestrial or airborne LiDAR, sonar, range imaging, and conventional survey methods) can better inform our understanding of morphodynamics across a variety of earth surface environments  (e.g. fluvial, riparian, upland, coastal and estuarine). We welcome contributions that detail all aspects of the collection and analysis of high-resolution topographic and bathymetric data, with particular focus on the development of robust error analyses, and on leveraging these data to understand and quantify geomorphic processes.
