Currently, all forecasts of currents, waves, and seafloor evolution are limited by a lack of fundamental knowledge and the parameterization of small-scale processes at the seafloor-ocean interface. Commonly used Euler-Lagrange models for sediment transport require parameterizations of the drag and lift forces acting on the particles. However, current parameterizations for these forces only work for spherical particles. In this dissertation we propose a new method for predicting the drag and lift forces on arbitrarily shaped objects at arbitrary orientations with respect to the direction of flow that will ultimately provide models for predicting the sediment sorting processes that lead to the variability of shell fragments on inner shelf seafloors. We wish to develop the drag force parameterization specifically for a limpet shell through the linear regression of force estimated from high-fidelity Reynolds-averaged Navier-Stokes (RANS) simulations in OpenFOAM
