Abstract
To reduce victims for a disaster that is due to rainfall, we are advancing the development of the system, which support evacuation decision-making for the persons in charge of the disaster prevention and the concerned residents. The objective of our research is that we specify the direction of evacuation decision-making, which is shown by the areal unit. For the uncertainty of the calculation accuracy, we start with the reproduction calculation on the 2011 Totsukawa event. To implement the above-mentioned objective, the risk index of the sediment disaster is estimated. The accuracy of the calculation result is validated by collapse record and others.
