The class explores structural engineering approaches for the design of structures such as bridges, sea walls, breakwaters, and piers in the coastal and riverine environment. A focus is placed on the loads and the water-structure interaction; thus a background in partial differential equations is needed for the following subjects, which are explored in depth: wave theory and random waves, hydrostatic and hydrodynamic forces on structures, structural design for wave and wind, analysis and design of floating structures including hydrostatic stability.
