I hope that I can contribute by helping us move towards solving them. I think a good way of understanding the next steps in how surface processes interact with long term tectonic processes is to catalog the current capabilities and limitations of our models. Some questions that I would like to ask and help answer are: What are our current numerical landscape evolution models good at, and how can we tell? What results can our landscape and tectonic models not reproduce? What are the missing processes that our landscape evolution models need to reproduce these results? What are the numerical and computational obstacles stopping us from incorporating these processes? From my adviser, Gary Parker, I have learned a great deal about reduced complexity modeling, and I know that adding extra complexity to a model adds extra complexity to the numerical and computational aspects of the code as well as complexity to the interpretation of the results. A problem I am currently working on involves understanding the feedbacks and interactions between landslides and landscape evolution. Landslides are important to landscape evolution because they can provide sediment that incises the beds of rivers by acting as an abrasive material. To study these interactions, I need to resolve how sediment moves within the landscape by coupling alluvial morphodynamics with a landscape evolution model. Currently, this incorporation into my code requires the time step in my model to be much smaller than what long-term landscape evolution and tectonic models normally use. I want to help develop a way to couple these spatially small and temporally short alluvial processes to large-scale and long-term landform processes in an efficient manner. This meeting would be a good opportunity to find others whom are interested in working on this problem or want to collaborate on other new ideas.or want to collaborate on other new ideas.
