京都における文化財を含む地域の土砂災害危険領域に関する一考察 PREDICTION OF SEDIMENT HAZARDS ZONE IN THE RESIDENTIAL AREA WITH CULTURAL HERITAGE IN KYOTO CITY
Access this Article
A preliminary study is conducted to propose countermeasures for residential areas with cultural heritage as well as for residential area against sediment hazards such as landslide and debris flow, focusing on part of Kyoto City. Firstly, the spreading of residential area in Kyoto City is discussed using both a latest topographic map and an old map published before about 90 years. Secondary, in order to obtain the simple and physically reasonable methods for evaluating the sediment hazards, the validities of predictions obtained using the governing equations of mass point system for soil block's dynamics is confirmed in terms of the calculated results using 1 D. governing equations of debris flow and the data obtained by field investigations.<BR>A critical line of sediment hazards zone predicted using momentum conservation equations of mass point system suggests that occurrences of sediment disaster are inevitable in present residential regions and, additionally, several cultural architectures are located in sediment hazards zone.
