SHOCK PRESSURES OF BREAKING WAVES.

Abstract

Apart from a few tests by C. W. Ross, breaking waves preceded by nonbreaking waves have not been systematically investigated. Since such waves are likely to occur in nature and since solitary waves usually give higher pressures than corresponding consecutive breaking waves, this type of waves - the breaking wave preceded by nonbreaking waves - should be of interest. Not much is known about the probable and possible horizontal distribution of shock pressures. In spite of work by others, more information is needed on the simultaneous vertical pressure distribution against a wall. No previous investigation involves a systematical, more detailed study of the pressure-time registration. The shock impulse and its distribution as well as the oscillation period and/or the duration of the shock pressure caused by the expected waves are important information for the design engineer. The main purpose of this investigation has been to fill some of these deficiencies in knowledge.
