Abstract

In recent years, the importance of the having a good natural environment in harbors and coastal areas is widely recognized. The formation of seaweed beds and fish gathering are desirable in a wave dissipating concrete block. Reduction of construction cost is also important. We decided to develop a superior wave dissipating block to effect both "eco-friendliness" and an economic solution. The block has high stability and a wave dissipating function as good as any conventional wave dissipating block. Field observations were carried out on to confirm its "eco-friendly" effective.
