HYDROGEOLOGICAL BREAKING CHARACTERISTICS OF WAVES ABOVE FRESH WATER SUBAQUEOUS SOURCES

Agatino D'Arrigo

Abstract


After a short review of the usefulness of maritime structures, particularly vertical wall breakwaters, long term observations of hydrogeological breaking on the bottom of Italy's Seas, as caused by the subaqueous source of fresh water, are discussed. The correlation between hydrogeological breaking and wave motion perturbation produced by compressed air or by oil is presented. These considerations are related to the observations of Admiral Alessandro Cialdi on the morphological breaking of waves above sand banks, thus producing calmness in the upper water.

Therefore, it appears possible to establish a very suggestive analogy between the atomic disintegration of the transformation of potential energy of the oscillatory tide wave into kinematic energy of its components (because of breaking), in accordance with the disintegration of the circular motion.
