Numerical modeling of earth surface processes, including geomorphic flows, contributes to understand the evolution of the surface of the earth, alongside observation and theory. Numerical modelling provides powerful tools for exploring potential interactions between different processes, and is particularly valuable given the difficulties in obtaining observations that span a wide range of scales, from grain-scale processes to the large temporal and spatial scales involved in landscape evolution.
This limitation also makes it difficult to validate theories and the models that build upon those theories. Because of this and because of recent advances in model complexity, many modern models remain poorly validated. As such, it is more important then ever to make an attempt to validate current models through observations of modern processes or detailed case studies.
The scope of this session is broad, and we welcome studies that utilize or develop numerical models of all types of surface processes, and all relevant morphological scales, from grain-scale interactions that determine the rheology of geomorphic flows to large-scale landscape evolution with interactions with climate and/or tectonics.
In particular, we wish to invite submissions that explicitly validate predictions with empirical data or provide clearly testable hypotheses. Also, innovation in numerical discretization techniques (mesh-based methods, meshless methods) and implementation strategies (CPU, GPU) are welcome.
