This research is concerned with studying questions regarding               open boundary conditions for wave propagation problems and with                 implementing numerically these boundary conditions.  The topics                 on investigation include an analysis of the effect on Rayleigh                  waves of radiation boundary conditions previously developed by                  the investigator for elastic body waves, the development and                    analysis of radiation conditions for water waves, and the                       investigation of some theoretical questions involving derivative                boundary conditions that rae used at open boundaries.  The first                two problems will require extensive numerical computation.
