3-4-1. Basic Research on Hazard Map for Glacial Lake
Outburst Flood in Bhutan
3-4-1-1. background
Upon the request of Bhutan, one of the ADRC member countries, with the urgent need toestablish countermeasures for Glacial Lake Outburst Flood (GLOF), which could be causedby climate change, the ADRC planned a project for capacity development on community level.
As a feasibility study for the project,

the ADRC has been implementing basic research since

FY2009. In FY2010, the basic study to make hazard map of GLOF in Bhutan was conducted.

3-4-1-2. Survey(1) MOU
The ADRC visited Bhutan in August 2010, and had a series ofmeetings with theDepartment of Disaster Management (DDM), the Department of Geology and Mines (DGM),
the Department of Energy (DOE), and the Japan International Cooperation Agency (JICA),
which had already begun work on another GLOF project. The ADRC also visited Punakha
province, the prospective project site, exchanged views with the provincial governor andschool principals, and toured the DOE's early warning center. Thesituations in the province

were described as follows:- GLOF occurred along the Po River in 1994, and the UNDP was already conducting aGLOF project on the Po River.
- Five glacial lakes in the upstream regions of the Mo River were identified as being at riskof GLOF flooding. But their risk level was low and constant monitoring in those areas
would be difficult.
- Due to a lack of data, it was difficult to estimate the river water levels that would result
from GLOF flooding.
After careful consideration of the situations,the ADRC and DDM finally agreed on atwo-year cooperative project, which would:- Focus on the Mo River, which flooded in 2009.
- Install community-based river level gauges, and develop an early warning system.
- Create a map with elevation data in the upstream areas of the Mo River.
- Create a hazard map based on past flood records in Punakha- Conduct disaster education and training among local residents.

(2) Field Survey
The ADRC have conducted field survey two times on Punakha and Mo Rivers in Augustand December 2010 respectively. At first, the ADRC visited Punaka-zong area to collectinformation concerning past floods, a GLOF at Po River in 1994 and2009. It was found that theflood at Mo River inwater level of the Mo River in the case of 2009 was higher thanan expected water level in 1994. Also the sizes of glacial lakes in the upstream Mo River
were smaller than the ones of Po river. Therefore, it was decided that a GLOF hazard map
would

be made by utilizing a flooding area in 2009 as reference.

(3) Considerations for FY2011
The water level monitoring sites will be decided after discussion at a workshop to be heldin 2011 to set up river gauges.
The ADRC will also create a GLOF hazard map of the Mo Riverby utilizing theimagery of “DAICHI”, a space satellite operated by JAXA. This hazard map will be modified
at the workshop by related organizations24

3-4-2. Transmitting Images of Disaster-Stricken Area andProviding Lessons in Image Analysis Techniques(1) Emergency observation
From April 2010 to March 2011, 39 emergency observation requests were received and 20
emergency observations were performed. Table 3-4-2-1 provides details of the emergency
observations performed during this period. When emergency requests are received, ADRC's
emergency request administrator decides whether the request is appropriate and whether theobservation will be performed.

3. Collection and Distribution of Disaster Information(2) Seminar and International Conference on Sentinel Asia
Sentinel ASIA Joint Project Meeting (JPTM) was held in Manila, the Philippines on 5-8
July 2010. It was organized jointly by Japan Aerospace Exploration Agency (JAXA), UnitedNations Economic and Social Commission for Asia and the Pacific (UNESCAP) and
Department of Science Technology (DOST), Gov. of the Philippines. 71 people from 22countries (36 organizations) and 5 international organizations participated in the meeting.
The ADRC functions as a single window to receive emergency observation request for theirscreening and onward transmission to space agencies in the framework of Sentinel ASIA. At
the meeting, ADRC reported the status of the emergency observations which wereimplemented last year, the results of survey on how provided satellite data was utilized ineach country, and the current situation of the ADRC GLOF project. The themes of discussion
in this meeting are as follows: Progress of Sentinel Asia step2
 Current situation of each JPT member
 Activities of Forest fire Working Group Activities of Flood Working Group Activities of Glacier Lake Outburst Flood (GLOF) Working Group Collaboration with Sentinel Asia and International Disaster Charter
The ADRC will continue to promote the use of satellite data for disaster risk reduction inAsia in cooperation with Sentinel Asia secretariat.
