Each person in the household takes action based on there own role, when flood disaster happens. In particular, it is estimated that a householder takes the leadership on the action of other household person. He lets person of tender age and advanced age with first priority evacuate, and takes preservation behaviours of their possessions. There is, however, a high possibility of causing a number of victims, as he tends to delay or abandon evacuation because of these behaviours. In this study, we analyze that the allotments of household exist in any pattern and then have any influence on evacuation activity of each person in household, and the characteristics of household behaviour in flood disaster in Koriyama-City due to heavy rainfall at the end of August 1998.
