Earth Surface Processes and Flooding
Session ID#: 74970
Session Description:
Earth surface processes affect flooding by altering surface and subsurface flow pathways and the capacity of river channels to convey water but such processes, in turn, are also shaped and affected by flooding, generating complex dynamics and feedbacks. Despite this, changes in flood risk are often perceived as being driven exclusively by hydro-climate and/or land use changes and geomorphic processes are usually neglected from flood models. This session will provide an entirely different perspective whereby geomorphology is recognised as being a key driver of flooding. We welcome contributions from across the earth’s environments, including uplands (where, for example, glacier retreat and/or landslides can dam valleys), river channels and their floodplains, and the world’s deltas and coasts. Contributions will highlight the key role of geomorphology has in modulating flooding, thereby enhancing our understanding of how these links and feedbacks impact on the assessment of evolving flood risk across our changing world.

Iceland has become a literal “hot-spot” for tourism because few places provide classic examples of plate tectonics, volcanoes, glaciers, & geothermal energy in one pristine environment. In this poster I will highlight a new advanced geology textbook called Iceland: Tectonics, Volcanics, and Glacial Features (Wiley, December 2019). (487034)
