Description: Technical note
Discussion:Rubblemound coastal structures contain voids between individual armor units. Structure voids maximize turbulent wave energy dissipation, but also allow passage of water and sediment. The volume of sediment passing through some jetties and terminal groins can be substantial, resulting in increased channel shoaling, higher maintenance costs, and significant loss of beach material. Most sediment infiltration problems are recognized from the resultant sediment distribution pattern. However, measuring the quantity of sediment infiltrating the structures is difficult. The extent of sand infiltration may be measured through visual observations, surveys, dredging records, aerial photographs, sediment traps, and dye tracers.
