The area of the lower Kiso three rivers (Kiso, Nagara and Ibi river) is almost below-sea-level area. The area was suffered heavy damage from the storm surge caused by the huge typhoon that is called "Isewan-Typhoon". After the disaster, the structures such as levees which are against tidal wave have been built. However, the storm surge disaster of the scale more than structures may occur because of global warming. So, it is important to make residents appropriately evacuate so that they are not sacrificed to the disaster. Then, the authors developed the comprehensive simulation that expressed the flooding of storm surge that assumed "Super-Isewan typhoon" and the residents' evacuation, and clarified issues of measures of evacuation against storm surge. Moreover, we performed the lecture to inhabitants. This paper reports the results of the activities and future prospects.
