Title: Water motion over complex topography in the coastal ocean
Abstract: Many important coastal marine systems have very rough, complex bottom topography that affects both circulation patterns and wave energy that reaches the shore. I will describe the physical processes that occur when currents and waves interact with complex bottoms, and how these processes can be represented mathematically in oceanographic models. I will discuss the challenges and unknowns associated with representing flow over topography that varies at a continuous range of length scales, contains large elements, or includes flexible components. The talk will include examples from coral reefs, salt marshes, and idealized simulations, and discuss potential applications to nature-based shoreline protection.
