This site contains animations and data of erosion on a small scale and numerical landscape erosion models. Erosion on small scale models were developed in an erosion facility that allows a miniature landscape to erode through several relief distances at constant base level fall and rainfall rates. Numerical landscape erosion animations are modified from published models with changes to numerical lattice boundaries such as stream curvatures, hillslope failure and directional diffusion. Tables and diagrams provide spatial and temporal statistics of experimental landscapes. Also available on this website are PDF versions of Les Hasbargen's publications and presentations.
