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.
