Lessons Learned for Thailand Flood 2011

There were 5 typhoons in 2011 that affected Thailand- HAIM, NOCK‐ 21-25 June; TEN- 26-31 July; NESAT- 24-30 Sep ; HAITANG 25-27 Sep and NALGAE- 27 Sep-05 Oct which bought enormous amount of rainfall which was the main cause of flood 2011. On an average Thailand face 1.5 every year. Only 1962 and 1971 was the last time that Thailand faced 5 times typhoon in the country. The rainfall amount since 1 Jan to 31 Oct 2011 was 1822.4 millimeters, about 28 % above normal and only Oct rainfall was 201.8 millimeters, 10 % above normal. There is no reservoir in Yom river, and during Aug- Sep Bhumibal and Sirikit Dam can’t release much water. Thus this region frequently experiences floods in Aug-Sep.

RIMES 1-15 days forecasts model well captured North Western Pacific storm reaching Thailand. Similar model integrating reservoir component could provide a well decision support system for water management authorities. Some recommendations on improvement of flood risk management of Thailand are:

• Authority should stop seeing floods as ad-hoc disasters in need of short-term relief, but as serious threats to both economic and social development

• A decision Support system for Integrated Water Resources Management should be developed providing priority on water supply, Reducing flood damages, hydropower generation, Securing navigation, environment etc.

• Water Saving Technology: updates water rule curve

• Integrated Reservoir modelling for robust monitoring system

• Floods shouldn’t be look as ad-hoc disasters in need of short-term relief, but as serious threats to both economic and social development

• Improved data acquisition from upstream dams regarding flood water release decisions and flood inundation and impacts scenarios (modelling)

• Improve coordination of inter-Governmental institutions and reduce disaster diplomacy!

• No matter how state-of-the-art they are, engineering solutions do not last forever. They become obsolete as the environment and living conditions change.

• Capacity building of communities on newly generated forecasts products, interpretation and response to flood disaster

Dr Fakhruddin is an expert climate change risk assessor with 18 years’ global experience in working on disaster risk and climate resilience projects. This experience is a major advantage in climate change adaptation and mitigation strategy development. His key areas of expertise are climate and multi-hazard risk assessment, disaster preparedness, early warning and emergency response and coastal community resilience. He has designed climate change and disaster response projects more than 25 countries in Asia and the Pacific. During his career, Dr Fakhruddin helped to design major international multi-hazard early warning systems for floods, cyclone and tsunami to save life and property damage. His most high profile work has been developing multi-hazard warning systems including a tsunami warning system for Indian Ocean countries following the deadliest one in history - the 2004 Boxing Day Tsunami. Dr Fakhruddin is currently work as a mentor and supervisor for postgraduate study in disaster risk management in University of Auckland (UoA). He is a Science Committee Member of IRDR of ICSU/UNISDR, Co-Chair for the Disaster Loss DATA and Risk Interpretation and Applications (RIA) Working Group of IRDR of ICSU/UNISDR. He is also Co-Chair CODATA task group Linked Open Data for Global Disaster Risk Research (LODGD) and PSG member of the Coastal Inundation Forecasting Demonstration Project (CIFDP) and Open Panel of Commission for Hydrology Experts (OPACHE) of WMO. Recently Dr Fakhruddin appointed by the Government of New Zealand to develop national climate change risk assessment framework
