Countermeasures against Flotsam at Channels and Basins of Alternative Ports after a Large-scale Tsunami Disaster

Abstract

ABSTRACT : If a large-scale tsunami disaster damages a wide area, there is a strong possibility that important functions of ports located in the area are not restored within a short time because of shortage of floating cranes and grab dredgers to clear flotsam at channels and basins of ports. In such a case, it is useful to transport important cargoes by using other ports. However, it is quite likely that a relatively small amount of flotsam appears at these ports. This paper discusses countermeasures against the flotsam.
