PD Dr. Christian Winter

In our research group we pursue a process-based understanding of coastal hydro-, morpho-, and sediment dynamics. Coastal morphodynamics are understood as the physical drivers of eco-systems. They involve a bandwidth of spatial and temporal scales: from the microscopic interaction of turbulent fluid motions with single particles to meso-scale tidal dynamics of subaqueous bedforms to macro-scale seasonal adaptations of beach profiles or the development of tidal channels, to the mega-scale evolution of shorelines over decades.

We apply a synthesis of hydro-acoustic and optical field observatios, laboratory experiments and numerical model simulations to address different research questions in the fields of:

• the formation, development and hydraulic effect of bedforms,
• the morphodynamics of tidal inlets and beaches,
• the dynamics of suspended matter and fluid mud.
