Integrated disaster risk management strategy to prevent exposure to hazardous substances due to inundation triggered releases: a concept for Japan
The Nobi plain in Aichi Prefecture is exposed to multiple hazards, like inundation, typhoons and earthquakes. One serious threat is given by typhoon-triggered inundation as happened in the year 2000 during the Tookai-flood. This threat increased in the last decades because of land subsidence triggered by exhaustive ground water withdrawal in the mid of the 20 th century (Yamamoto, 1984). Several facilities handling hazardous substances were inundated during this event. It is unknown if hazardous substances were released. Similar cases suggest that this is highly probable. E.g., during the 2002-Elbe-flood in Germany large amounts of contaminants like heavy metals were flushed into the Elbe river. This resulted in chemical loadings, up to three magnitudes higher than the normal river load. The total delivered load of lead was 2500 times higher than the annual average load. The origin of those chemicals were determined to be inundated chemical facilities located in the Czech-Republic (Schiemeier, 2002). This example shows that not only the loss of property and life is of concern to disaster managers, also consequences by inundation-triggered events, like releases of hazardous substances have to be considered (Christou, 2000;
Integrated Research on Methodological Development of Urban Diagnosis for Disaster Risk and its Applications
Synopsis As a part of DPRI-COE research activities, our IMDR Division has conducted an extensive methodological research on integrated disaster risk management, with a focus on “urban diagnosis.” This paper outlines the major research achievements made within this framework. First the definitions of key concepts and methodological framework are explained briefly. Then representative research activities conducted by our Division team are specifically described and further research efforts to be made in the remaining phase of the COE research project are addressed.
International EMS systems: New South Wales, Australia.
Australia has an area of 7,692,024 km 2 and a population of 19,169,083. The state of New South Wales (NSW) has an area of 801,428 square kilometres and a population of 6,663,700 (June 2002). It contributes 10% of the land area of Australia and 34% of the population. The length of the coastline is 2007 km with an east-west distance of 1450 km (Fig. 1). Approximately 90% of the NSW population resides within 100 km of the coast. The population density is greatest in the Greater Metropolitan Region around Sydney, an area of 1580 square km, population of 4,154,722. Only 0.6% live in regions classified as remote or very remote (based upon distance to regional townships). The climate is generally mild, although temperature extremes range from � /20 8C (Charlotte’s Pass) to 50 8C (far Western NSW). The highest point is 2228 m at Mt. Kosciuszko. However, most of NSW is below 500 m in altitude.
