The Proper Profile For Resisting Wave Action
In the correspondence contributed by the author to the paper by Theodore Cooper, M. Am. Soc. C. E., entitled “Some General Notes on Ocean Waves and Wave Force,” attention was drawn to the theory of waves advanced in 1831 by Col. A. R. Émy. The most novel feature of this theory assumes the existence under certain conditions of a bottom wave caused by the oscillatory waves nearer the surface. This bottom wave is a true wave of translation, which has little or nothing of an oscillatory character, and must exert horizontal energy nearly in proportion to its mass and the square of its horizontal velocity. The present paper is a continuation of the correspondence referred to, and discusses the best profile for resisting wave action.
One of the most common modes of failure of sea walls with vertical front is the undermining of the foundations, or the wearing away and breaking up of the lower courses. Nearly every writer upon the subject makes mention of the common failure at the foot of the works. This is often said to be caused by the “undertow,” or the suction and downward motion of the water at the wall.
