Models are developed and solved to describe the flow of and deposition from low and high concentration turbidity currents. The shallow water equations are amended to include particle transport to describe the low concentration turbidity currents. The suspension balance model is used to describe the high concentration turbidity currents. Numerical simulations are developed to solve the highly non-linear, free boundary problems associated with these models. Simpler, algebraic scaling relationships are also developed for these models. The models are successfully validated against field observations of turbidites. With these models, one can take seismic information on the shape of the turbiditic deposit and estimate the particle size, which can be used to determine the porosity and permeability
