To slide or not to slide: the evolution of topography and sediment dynamics in landslide prone regions by Benjamin Campforts, Institut of Arctic and Alpine Research, University of Colorado, Boulder
From an engineering perspective, we often think of landslides as a natural hazard that predominantly occurs in steep terrain. Yet from a geomorphologic perspective, landsliding itself contributes to shaping the topography. If we want to understand how landscapes change through time, quantifying the role of landslides is key. In this seminar, I explore the impact of landslides on landscape evolution using a novel numerical model (HyLands, see inset figure). We will discuss how numerical models can help to understand landscape response to environmental perturbations, such as earthquakes or increased storm activity under a changing climate. I will further outline strategies to use numerical models and data assimilation techniques to better understand, quantify and predict future landslide risk in alpine and arctic regions.
