Landlab is a Python toolkit for building, coupling, and exploring two-dimensional numerical models of Earth-surface dynamics. Hydroshare is an online collaborative environment for sharing data and models. Hydroshare allows users to run models remotely, without needing to install software locally. This clinic will illustrate example Landlab models and how to run them on Hydroshare. This clinic will provide an introduction to Landlab’s features and capabilities, including how to create a model grid, populate it with data, and run numerical algorithms for surface hydrology, hillslope sediment transport, and stream incision. We will illustrate how models can be used for both research and teaching purposes.
