Horizontal mass exchange in large lakes and coastal waters

This PhD thesis focuses on the horizontal mass exchange of large lakes and coastal waters. For large lakes, a pseudo three-dimensional hydrodynamic model with Lagrangian flux paths has been developed to bridge the gap between the computationally efficient, but spatially inaccurate one-dimensional or pseudo two-dimensional models and the computationally expensive, but spatially accurate three-dimensional models. For coastal waters, the hydrodynamic exchange of a macrotidal forced coupled bay-estuary system with multiple inlet channels has been elucidated, aiding in our understanding of mass transport in topographically complex coastal systems.
