Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan
International Journal of Erosion Control Engineering Vol.5, No.2, 2012 Disaster Report Three Large Historical Landslide Dams and Outburst Disasters in the North Fossa Magna Area, Central Japan Kimio INOUE1, Toshio MORI2 and Takahisa MIZUYAMA3 1Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) Email: [email protected]) 2Sabo Frontier Foundation (Sabo-Kaikan, Hirakawa-cho 2-7-4, Chiyoda-ku, Tokyo 102-0093, Japan) 3Division of Forest Science, Graduate School of Agriculture, Kyoto University (Kitashirakawa, Sakyo-ku, Kyoto 606-8502, Japan) Large landslides or debris flows caused by heavy rainfall or earthquakes often block rivers in mountainous areas and form landslide dams. The area upstream of the landslide dam is submerged under water and the downstream area is flooded when the landslide dam breaks. In recorded history, as many as 22 landslide dams have formed upstream of the Shinano River and the Hime River, in the northern part of Nagano Prefecture in central Japan, and all except three have subsequently broken. This abundance of landslide dams is probably caused by the geotectonic background of this area, which is located at the western end of the “Fossa Magna” major tectonic line. In this study, we examined three large historical landslide dams and outburst disasters in the north Fossa Magna area. Keywords: Landslide Dam, Debris Avalanche, Tobata Landslide, Zenkoji Earthquake, Mt. Iwakura Landslide 1.

Long-Term Estimation on Nitrogen Flux in the Yamato River Basin Influenced by the Construction of Sewerage Treatment Systems
AHW32-P08 JpGU-AGU Joint Meeting 2020 Long-term Estimation on Nitrogen flux in the Yamato River Basin Influenced by the Construction of Sewerage Treatment Systems *Kunyang Wang1, Shin-ichi Onodera1, Mitsuyo Saito2, Yuta Shimizu3 1. Graduate School of Integrated Arts and Science, Hiroshima University, 2. Faculty of Environmental Science and Technology, Okayama University, 3. National Agriculture and Food Research Organization The quantification of the nitrogen discharge in water were most important indicators of the water environment in coastal area because these processes are related to the transport of large nutrient loads. The nitrogen pollution sources of the surface water environment are divided into point source pollution and non-point source pollution according to the different spatial distribution (Niraula et al. 2013; Lee et al. 2010). Nonpoint source nitrogen pollution is a leading contributor to world water quality impairments. (Steffen et al 2015). Sewage treatment system can significantly reducing pollutant emissions by multiple methods. The construction of sewage treatment systems does not happen overnight, it is divided into two parts: construction of sewage treatment plant and laying of underground pipelines into buildings. Especially for plumbing system, it is a long process. During this period, non-point source pollution from urban areas will be gradually transformed into point sources. Yamato river is a very important river in west Japan. It has a watershed area of 1067 square kilometers, covering almost half area of Nara prefecture. These have 5 sewage treatment plant in the watershed, 3 of them are located in Osaka Prefecture and others are in Nara Prefecture. These sewage treatment plants were successively constructed and put into use between 1974 and 1985. -
