  • CONTROL OF SEDIMENT TRASPORT BY BaNK BLOCKS WITH DIRECTIONAL RESISTANCE PROPERTIES

説明

The problem of beach erosion in our country grows more and more serious, so we must countermeasure against this problem without delay. Then we develop a effective method (we call the blocks used in this method BaNK block) to control sediment transport to cope with this serious problem. In this paper, we examine the fundamental properties of this method by laboratory experiments and field works in Nogita Coast. Firstly, we investigated the condition of flow occurrd when BaNK blocks were set in a wave progressing field by laboratory experiments. We confirmed that this method could make a flow at bottom layer and made a proper layout of BaNKblocks dear. Secondly, we set two kinds of blocks in Nogita Coast and observed a sediment transport around these blocks. By this field works we confirmed that sediment was transported by BaNKblocks to the direction we expected. From these results, we confirmed the possibility of beach nourishment by using BaNK blocks.
