A study of wind stress and boundary effects on sea level and coastal currents
This thesis includes both a discussion of free and forced topographic trapped edge waves over various continental shelf profiles, and an examination of the boundary effects on sea level coastal current movement through a strait or channel. Using the linearized long wave theory and the methods of com...
