This lab consists of three notebooks that … This lab consists of three notebooks that use the mesh generator ''dmsh'' and the mesh generator from Anuga to create unstructured grids that are passed into Landlab. The examples contain code for creating Landlab models using these other mesh generators as a starting point. Only the flow accumulation and drainage area components are demo'd, but there are many other questions one might want to ask about the influence of cell resolution (and local cell resolution) on different landscape evolution processes.n different landscape evolution processes. +
