WAVE INVESTIGATIONS IN SHALLOW WATER

open access: yesCoastal Engineering Proceedings, 1970
Examination of the significant heights of zero-crossing waves in the Elbe Estuary has yielded two noteworthy results: 1 In the deeper water of the estuary, the value of the quotient relating the significant and the mean wave heights is larger than on the bordering tidal flat. 2. The value of this function is dependent on the height of the waves; on the
