Unraveling the role of extreme climatic events in surface processes and landscape evolution
Convener: Yuval ShmilovitzECSECS | Co-conveners: Jacob HirschbergECSECS, Matthew Rossi, Roberta ParanunzioECSECS, Francesco Marra
Many regions of the world are experiencing an increase in the frequency of extreme climatic and meteorological phenomena, such as heavy precipitation downbursts, heatwaves and sea-wave storms. These events cause a multitude of severe hydrogeomorphic responses such as floods, flash floods, hillslope erosion, (ice) cliff failures, debris flows, landslides, rockfalls and rock avalanches. A better understanding of surface processes under extreme climatic events can be of critical importance for hazard assessment in a changing climate and for deciphering signatures of past extreme events in landforms and sediment records. However, measuring, evaluating, and predicting the interplay of extreme climate conditions and surface processes is challenging as it often requires an event-based perspective.

This interdisciplinary session focuses on the causative chain which links extreme climate forcings, surface processes and landscape evolution, from hillslope, to watershed scale and beyond. We welcome studies from all climates and at all temporal scales; from the event scale to the long-term integrated impact of extreme events on the landscape. We especially encourage studies presenting new modeling and measuring approaches of surface process dynamics during extreme events to consider our session.
