Mark Schmeeckle, professor of geography, focuses his work and research on landscape mechanisms, specifically his interests are in the transport of sediments.
Schmeeckle is currently developing a set of LES and hybrid techniques for turbulence in environmental flows. Sediment transport is then calculated using the LES results either by bedload calculations from the temporally- and spatially- varying bed stress, or by 3D advection-diffusion modeling of suspended sediment.
He is also building a suite of environmental morphodynamic models involving 3D steady RANS calculations for environmental flows. At each time step sediment continuity is solved and the 3D structured or unstructured grid is adjusted accordingly. This modeling system is being developed for simulation of bar growth in rivers and large-scale erosion and deposition of eolian landscapes.
