This session aims at cross-cutting issues between natural hazards and geomorphological research. While having enjoyed renewed attention in the Earth sciences in the wake of “neo-catastrophism”, extreme events begin to play an important role in natural hazards research and practice. Once largely neglected as improbable, the anticipated consequences of climate and land-use changes now underline the pressing need to further our understanding on the extreme behaviour of geomorphic systems driven by discrete events or exceedance of critical thresholds.
Average return periods, event magnitudes, and damaging potential of such worst-case scenarios are currently a black box in many natural hazards assessments. However, there is now a growing number of geomorphologic case studies that may contribute to filling this knowledge gap. Conversely, a highly desirable systematic approach to these empirical studies may benefit from quantitative analysis techniques and extreme-value statistics used in natural hazards assessments.
We thus cordially invite contributions that highlight and/or quantitatively underpin both direct and subsequent effects of extreme events on sediment flux and topography in mountainous regions, with a view to derive from them information pertinent to hazard assessment. We welcome submissions on case studies on earthquakes, rainstorms, high-magnitude floods, wildfires, etc., and their impact on mountain-relief production and destruction by means of e.g. catastrophic slope failure, bedrock channel scour, coarse floodplain aggradation, natural dam breaks, river metamorphosis, or other significant types of surface deformation over a range of spatial and temporal scales.
