From Ridgelines to Valleys: Hillslope Processes, Morphology, and Evolution Across Scales
Session ID#: 249200
Session Description:
Hillslopes are a fundamental geomorphic domain that account for a significant proportion of landscape area. Hillslope processes span a wide range of scales from the breakdown of minerals to granular creep to landslides to morphologic adjustment to tectono-climatic forcings. Advances in process-based understanding of hillslope morphodynamics across spatiotemporal scales have been augmented by improved monitoring, technology, numerical modeling, and theory. This session seeks contributions that integrate process-based and morphological understanding of hillslopes across scales, including advancing models of hillslope sediment transport and interactions with topographic variability from grain- to landscape-scale; establishing linkages between soil production, geochemical fluxes, organic carbon storage, and sediment transport throughout the Critical Zone; interrogating hillslope and landslide response to perturbations such as fire, extreme climatic events, tectonics and drainage reorganization; demonstrating connectivity or feedbacks between bedrock weathering, hillslope transport, and fluvial processes; inverting tectono-climatic processes from hillslope form; and applying novel geochronometers and remote sensing techniques.
