Understanding Quaternary to modern landscape change calls for robust chronological frameworks along with, a thorough process understanding and comprehensive models of Earth surface’s dynamics and evolution of environmental conditions. During the last decades, geochronological techniques (such as trapped-charge dating, cosmogenic nuclides and thermochronology, among others) have significantly improved their precision, accuracy and wide applicability to various geomorphological or sedimentological targets. The combination of numerical dating and landscape (evolution) models give important insights into the timing, duration and intensity of geomorphic processes. This session aims to bring together new research focusing on conceptual, methodological, or modelling approaches (or combinations of these) to study Quaternary landscape evolution under various forcing (climatic, environmental, tectonic or anthropogenic).

We invite presentations that measure geomorphic signals, including landscape dynamics, erosion rates and processes, sediment provenance, burial times and transport rates, bedrock temperature or cooling histories and surface exposure times. In addition, contributions that examine potential biases and discordances in geochronological data and model-data comparisons are welcomed. We are looking forward to contributions from all parts of the geo-community.
