2. Information on the water-related disasters in FY2011
Secretariat gathers information on water-related disasters of the
world. Major water-related disasters in FY2011 (April 2011- March 2012)
is shown on the world map on the below Website.
3. Development of Satellite-based Precipitation Data Delivery System
to the financial support by JAXA (Japan Aerospace Exploration Agency)
and RESTEC (Remote Sensing Technology Center) of Japan, IDI has
developed the Satellite-based Precipitation Data Delivery System, which
automatically provides satellite-monitoring precipitation data every
hour both for the river basin and for the administrative district. It
also notifies with different colors whether the accumulated
precipitation in some river basin or district exceeds the
pre-calculated probable precipitation with some return period (such as
once in two-years, or once in five-years).
trial version is now utilized by the Government of Thailand in order to
prevent and to be well prepared for flood disasters during flood season
The detailed information will be found on the below Website.
4. Restoration and reconstruction process after the Great East Japan Earthquake
year passed since the occurrence of Great East Japan Earthquake of
March 2011, restoration and reconstruction works are vigorously
undertaken in the disaster-affected regions.
of the tsunami-oriented massive debris and mud was removed from the
site to the temporary piling yards. However, only 9% of the pile-up
debris was incinerated. The prefectural governments are seeking the way
to incinerate the debris in non-affected regions, but still have not
yet fully got consent from local residence of these regions.
of the immediate restoration works are just about completed. From now
on, the full-scale restoration works needs to develop by reflecting the
opinion and requirement of local residence.
5. Flood prevention and mitigation in Niigata, Japan
is publishing a journal gIDI Quarterlyh, in which public works and
construction technologies in Japan are introduced. At present, more
than 900 persons of 90 countries subscribe this journal. The latest
edition (No. 59) of April, 2012 introduces miserable history of flood
disasters in Niigata Plain and the outstanding projects to prevent and
mitigate flood disasters. It highlights both structural measures (such
as constructing river bank, straightening river course and constructing
diversion channels to let floodwater directly flow into the ocean) and
non-structural measures (such as flood forecasting, early warning and
flood hazard mapping). Owing to the above efforts, flood damage in 2011
was far less than that in 2004, although the cumulative rainfall in
2011 was 1.6 times higher.
