Historical background and recent trends in dredging and reclamation technologies in Japan

Abstract

This article describes the history and development of ports and harbors in Japan, and new technologies of dredging and reclamation, particularly two methods recently developed with consideration of environmental concerns: (1) a high‐density pneumatic transport system to minimize the effect on the environment, and (2) a high‐density dredging system based on the same pneumatic transport system and capable of dredging a very thin soil layer, together with construction records of these systems.
