[1] Beach process

The Seacoast Law was amended in 1999, and obliged coastal conservation that would balance protection, the environment, and usage. In addition, sand beaches (only those designated by the authorities among the beaches developed by coast managers for maintaining certain functions such as wave absorption to protect coasts) were designated as coastal conservation facilities. Furthermore, maintenance and recovery of sand beaches are stipulated as the basis for improving all of protection, the environment, and usage. Thus, the creation of sand beaches by artificial beach nourishment, accompanied by maintenance and recovery of the beaches, is desired in future coastal conservation.

The Coast Division is engaged in research for understanding the variation process and stability of sand beaches required for implementing coastal conservation, as well as for understanding the properties of seashore deposits.
