Description
<p> Tsunami debris delay transportation of emergency supplies to the affected area after disasters. In particular, since a tsunami has potential to damage a wide area, it is important to know the number of work vessels necessary for removing debris from navigation channels in not only a target port but also neighboring ports in advance in order to achieve prompt transportation of emergency supplies in the damaged wide area. In this study, based on the Great Nankai Trough Earthquake and Tsunami cases the Cabinet Office estimated, we estimated the disaster debris by both the earthquake and the tsunami at five major ports of Ise and Mikawa bays, and the number of work vessels necessary for removing derbis from navigation channels within 3days after the disaster. The largest scale damage estimation induced that 7.8 work vessels were required for the whole Ise and Mikawa bays even for relatively light amount of debris that should be removed.</p>
