<p>A preliminary study is conducted to propose countermeasures for areas endowed with cultural heritage as well as for residential area against flood and sediment hazards, focusing on part of Kyoto. Disaster records during the latest fifty years show that water-induced disasters may take place when accumulated rainfall depth is over around 100mm, resulting in deaths and missings whenever a continuous rainfall is over around 120 mm. Relations between numbers of death and fully damaged houses are characterized by two envelop lines, in which the upper is closely related to sediment disasters and the lower is characterized by flood disasters. A critical line for sediment hazards zone predicted in terms of mass point system for soil block’s dynamics suggests that occurrences of sediment disaster are inevitable in present residential regions and in addition several cultural architectures are located in sediment hazards zone.</p>
