Research

Professor Raichlen and his students have been involved in a wide range of coastal engineering studies; their program deals mainly with wave mechanics and wave-structure interactions in the nearshore region. One example is the dynamics of harbors exposed to continuous trains of waves (or to transient waves) and their interaction with moored-floating bodies. Results of that research have provided the profession with a means of investigating harbor-ship dynamics in an exploratory or preliminary manner without resorting to more costly laboratory investigations.

An important area of research that is of great interest to Professor Raichlen and his students has been the generation, propagation, and coastal effects of tsunamis -- earthquake generated sea-waves. Current research emphasizes the coastal effects of tsunamis, such as their interaction with structures and the run-up of large tsunami-like waves that break near the shoreline. The latter have implications both with respect to run-up and the potential for damage to nearshore structures.

Another research interest is in the area of breaking waves. Studies have ranged from an investigation of the action of breaking waves on an armored bottom to the study of the mechanics of plunging breaking waves and the air entrainment by bow waves of ships. A tilting flume and two large wave tanks with glass walls, and equipped with programmable wave generators, are among the major pieces of experimental equipment available for coastal engineering research, along with a wide range of instrumentation.
