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.

CITY AND COUNTY OF SAN FRANCISCO LONDON N. BREED, MAYOR OFFICE OF SMALL BUSINESS REGINA DICK-ENDRIZZI, DIRECTOR Legacy Business Registry Staff Report HEARING DATE DECEMBER 9, 2019 MUMS – HOME OF SHABU SHABU Application No.: LBR-2019-20-008 Business Name: Mums - Home of Shabu Shabu Business Address: 1800 Sutter Street District: District 5 Applicant: Isidore Tam, Owner Nomination Date: August 5, 2019 Nominated By: Supervisor Vallie Brown Staff Contact: Richard Kurylo [email protected] BUSINESS DESCRIPTION Mums - Home of Shabu Shabu (“Mums”) is a family-owned Japanese American restaurant located on the first floor of the Kimpton Buchanan Hotel in Japantown. The restaurant was founded in 1979 as part of a project to bring Japanese culture to San Francisco by Kintetsu Enterprises Company of Osaka, Japan. It is currently owned by former employee Isidore Tam. Over the 40 years it has been in business, Mums has remained committed to bridging Japanese and American culture through its dining space and cuisine, becoming a vital gathering place for the surrounding Japantown community. Kintetsu Enterprises Company of America was founded in San Francisco in 1961 by Kintetsu Group Holdings of Osaka, Japan. The company sought to bridge Japanese and American cultures. They began in San Francisco, which had been Osaka’s Sister City since 1957. At the time, Japantown had recently undergone redevelopment so Kintetsu brought new life to Japantown by encouraging the proliferation of Japanese businesses in the area. They opened the Kyoto Inn in 1975 and, realizing that guests needed a place to enjoy Japanese food, opened what was then called Café Mums just four years later. -
Estimation of Flood Risk Management in 17Th Century on Okayama Alluvial Plain, Japan, by Numerical Flow Simulation
T. Ishikawa, et al., Int. J. of Safety and Security Eng., Vol. 6, No. 3 (2016) 455–465 ESTIMATION OF FLOOD RISK MANAGEMENT IN 17TH CENTURY ON OKAYAMA ALLUVIAL PLAIN, JAPAN, BY NUMERICAL FLOW SIMULATION TADAHARU ISHIKAWA1 & RYOSUKE AKOH2 1Dept. of Civil and Environmental Engineering, Hosei University, Japan. 2Graduate School of Environmental and Life Science, Okayama University, Japan. ABSTRACT In this study, the hydraulic function of the Hyakken-gawa Floodway, which was constructed in the 17th century to reduce the flood risk to Okayama Castle City, was evaluated by numerical flow simula- tion. The calculation conditions were determined by referring to the records about the floodway in old documents as well as from the numerical data based on the present conditions. The alluvial plain topog- raphy used for the inundation calculation was obtained from recent GIS data. The computation results showed that the flood control function of the floodway was composed of two stages: (1) Just before inundation occurred in the castle city, river water flowed into the floodway by collapsing the earthen dike located at the floodway head; this limited the increase in the river flow rate in the city area. (2) Just before the floodway capacity was exhausted, the backwater generated by the transverse masonry dikes in the floodway induced inundation to the paddy field region, which was on the side opposite to the castle city; this reduced the flood damage in the city area. The results also suggested that the civil engi- neers in the 17th century, who had neither the knowledge of modern hydraulics (including the concept of river flow rates) nor the advantage of using machinery for construction, presumably developed flood risk management strategies by combining the measures possible in those days. -
Dilution Characteristics of Riverine Input Contaminants in the Seto
Marine Pollution Bulletin 141 (2019) 91–103 Contents lists available at ScienceDirect Marine Pollution Bulletin journal homepage: www.elsevier.com/locate/marpolbul Dilution characteristics of riverine input contaminants in the Seto Inland Sea T ⁎ Junying Zhua,b,c, Xinyu Guoa,b, , Jie Shia,c, Huiwang Gaoa,c a Key laboratory of Marine Environment and Ecology, Ocean University of China, Ministry of Education, 238 Songling Road, Qingdao 266100, China b Center for Marine Environmental Studies, Ehime University, 2-5 Bunkyo-Cho, Matsuyama 790-8577, Japan c Laboratory for Marine Ecology and Environmental Sciences, Qingdao National Laboratory for Marine Science and Technology, Qingdao 266071, China ARTICLE INFO ABSTRACT Keywords: Riverine input is an important source of contaminants in the marine environments. Based on a hydrodynamic Dilution model, the dilution characteristics of riverine contaminants in the Seto Inland Sea and their controlling factors Riverine pollution were studied. Results showed that contaminant concentration was high in summer and low in winter. The Seto Inland Sea Contaminant concentration decreased with the reduction of its half-life period, and the relationship between Hydrodynamic model them followed power functions. Sensitivity experiments suggested that the horizontal current and vertical Residual currents stratification associated with air-sea heat flux controlled the seasonal cycle of contaminant concentration in the water column; however, surface wind velocity was the dominant factor affecting the surface contaminant concentration. In addition, contaminant concentration in a sub-region was likely controlled by the variations in river discharges close to the sub-region. These results are helpful for predicting contaminant concentrations in the sea and are expected to contribute to assessing the potential ecological risks to aquatic organisms. -

Geochemical Composition of Beach Sands from Tottori Prefecture, Japan
島根大学地球資源環境学研究報告 30, 65~72 ページ(2011 年 12 月) Geoscience Rept. Shimane Univ., 30, p.65~72(2011) Article Geochemical composition of beach sands from Tottori Prefecture, Japan Bah Mamadou Lamine Malick*, Erika Sano* and Hiroaki Ishiga* Abstract Fifteen sand samples were collected from ten beaches along the shoreline of Tottori Prefecture to determine their geochemical compositions, using X-ray fluorescence analysis. Two main river systems (Tenjin and Sendai Rivers) supply sediments to the shoreline from the Chūgoku Mountains. Beach parameters, such as the radius of the approximated circle and radian (ℓ/r), were used to describe beach forms: ℓ/R < 1 describes a short and concave pocket beach. Sands from the eight beaches investigated in the area contained more than 70 wt% SiO2, and are predominantly composed of quartz and feldspar. This was reflected in their geochemical compositions, with significant SiO2, Al2O3 and Na2O contents of the beach sand samples further indicating that quartz and feldspar are the main constituents. Detritus was derived from quartz-rich sources, and quartz dilution strongly influences the bulk chemistry of the beach sands. Positive correlation of most elements with Al2O3 and negative correlation with SiO2 suggests quartz dilution is the main control on chemistry. The sediments were derived from relatively felsic source rocks. Key words: Chūgoku Mountains, Tottori Prefecture, beach sand, geochemistry, quartz, feldspar area is thus needed. Introduction The purpose of this study is to describe the geochemical The compositions of coastal sediments are influenced by compositions of fifteen beach sand samples collected from numerous components and processes, including source ten sites along the shoreline of Tottori Prefecture in the area composition, sorting, climate, relief, long shore drift, and where the Sendai and Tenjin Rivers supply sediments. -
