A Development of Seaweed Type Textile for Sand Drift Control

The sand drift at beach has been accelerated in recent years and some structures such as groin, (offshore and submerged) breakwater have been constructed in order to avoid the beach erosion. The method of sand drift control proposed in this paper is focussed on the sand drift in suspention, bed load and saltation by making use of Seaweed Type Textile hydrodynamic resistance in the sea. The materials of Seaweed Type Textile is selected from the view points of the strength, fatigue and biology through the experiments of laboratory and theoretical analysis.The arrangement of the selected Seaweed Type Textile on the concrete foundation is also proposed in this paper because it strongly effects the stiffeness and sand trap characteristics.
