Hydraulic performance of porous vertical coastal Structures

Abstract

Porous vertical structures have been used for coast protection and for harbour structures. In the case of harbours these structures have been used as the principal breakwaters and as internal structures. The ability to predict the level of reflection and transmission plays an important role in the assessment of their hydraulic performance. This paper identifies the relative advantages of using porous vertical structures in practice and focuses attention on the hydraulic performance of a range of such structures with specific reference to energy dissipation characteristics in relation to their hydraulic design.
