The development of quantitative models of … The development of quantitative models of landscape evolution requires a rigorous assessment of how well they represent natural system dynamics. For some locations and processes, the models have been shown to provide reasonable representations of landscape dynamics over a range of timescales; however, in a number of cases, rather straightforward tests suggest our simplified approaches may require further development. I discuss some of these lingering issues in quantitative geomorphology with a focus on the ubiquitous ‘stream power model’ and show how different approaches offer potential solutions to implementation in landscape evolution models. I will show examples focusing on how climate and lithology are represented in landscape evolution models as well as discuss the limitations of representing a river channel with a 1-dimensional model. I summarize by suggesting that an iterative approach of numerical predictions, rigorous field assessment, and adjustment of theory is needed to fully capture and understand the dynamics of landscapes.and understand the dynamics of landscapes. +
