Water wave scattering by a spherical structure and an undulating bottom topogrphy in a two layer fluid

Abstract

This thesis studies i the interaction of water waves with spherical geometries in a two layer fluid of finite depth which is covered by either a rigid flat structure or a very thin ice shelf ii the scattering of water waves by different types of unevenness on the bottom surface under such situations To solve the ice covered problems the common idealization of ice as a thin elastic plate which is static in all but its flexural response is followed Furthermore the assumptions of linear
