2006 Oct, Tokyo, Japan

The 5th Japan-Italy Technical Conference on Sediment-Related Disaster Prevention was held in Tokyo on Monday, October 30, 2006. Total seven presentations were made in three different sessions: remote sensing, risk management (1), and risk management (2), and information and opinions on measures and researches in Italy and Japan were exchanged.

<<Remote Sensing>>

“Technology to analyze sediment movement and learn sediment disasters using satellite image”

2) Paolo Farina (Researcher, Earth Science Dept., University of Florence)
“Remote sensing technology and sediment disasters ? Examples in Italy”

<<Risk Management (1)>>

3) Hideaki Mizuno (Senior Researcher, Erosion and Sediment Control Div., Research Center for Disaster Risk Management, National Institute for Land and Infrastructure Management, MLIT)

“Risk management for sediment disaster measures in Japan”

4) Paola Reichenbach (Researcher, Research Institute for the Hydrogeological Protection of Central Italy, Perugia, National Research Council)
“Landslide disaster assessment in drainage basins and possibility to identify areas to be damaged”

5) Nobutomo Osanai (Head, Erosion and Sediment Control Div., Research Center for Disaster Risk Management, National Institute for Land and Infrastructure Management, MLIT)

3. Site Inspection

On November 1 and 2, following the technology conference and symposium, the party from Italy visited the Takizaka landslide area, which is under the jurisdiction of Agano river office, Hokuriku Regional Development Bureau and a model site of the joint research on landslides, and inspected restoration works for the areas devastated by mid-Niigata earthquake, which are under the jurisdiction of Nagaoka Regional Promotion Bureau in Niigata and Yuzawa Sabo Office of Hokuriku Regional Development Bureau.
