NEC Successfully Trials Flood Simulation System in Thailand


NEC Corporation announces its partnership with Thailand’s National Disaster Warning Center (NDWC) to trial its flood simulation system to predict the inundation areas in the event of flood.

Reported to scrutinize effectively, the pilot project was conducted in Uttaradit Province in Northern Thailand during the period from November 2015 to March 2016.

Thailand stays on an acute level of flood vulnerabilities; the 2011 Chao Phraya River flood caused large-scale flood damage to many industrial parks and urban areas, including Bangkok effecting the global supply chains, and economic upheaval. Therefore, flood disaster prevention is an urgent call in Thailand.

Offering from its wide portfolio, the “integrated risk management system” consist a shared platform that has functions such as data integration, visualization, and early warning, and disaster modules specialized for particular disasters such as flooding, landslides, and earthquakes. The disaster modules or functions can be selected individually as required, or several disaster modules can be combined in order to predict multiple disasters simultaneously.

Further, the system can perform detailed simulations using a triangular mesh measuring 50m on each side, and provide hourly-basis prediction for a period of up to seven days in advance. This allows NDWC to issue warnings to threatened areas before the flooding occurs, helping to reduce potential damage. Moreover, even during periods when no disaster is forecast, areas at risk of flooding can be identified by performing simulations using previous rainfall data, which enables hazard maps to be prepared.

“I firmly believe NEC’s flood simulator, which is one of the most effective disaster simulation systems for NDWC, will help us improve our operational efficiency. In order to benefit more from the system, we are considering to further expand the coverage area of the simulator,” said RADM Song EKMAHACHAI, Director of Warning and Dissemination Section, National Disaster Warning Center. “As our country is also facing risks of landslides, we have a high degree of interest for NEC’s landslides simulator. We are committed to mitigate damages from natural disasters and to save our citizens’ lives by continuously implementing these innovative ICT technologies.”

The flood simulation system performs a simulation based on meteorological data (observed rainfall and forecast rainfall), topographical data (elevation values, land use purposes), and watercourse data (river networks, water levels, sewer systems, etc.), making it possible to predict inundation areas, maximum flood levels, and other flood-related information.

“NEC will continue to contribute to the development of more sophisticated disaster prevention ICT and the use and application of the technology for preventing disasters in Thailand, such as flooding and landslides,” said Minoru Hirata, General Manager, Fire and Disaster Prevention Solutions Division, NEC Corporation. “Further, we will harness the experience and knowhow gained through this trial to actively promote the system to other countries in Asia that experience frequent damage from flooding.”

This trial is reported to be NDWC’s first disaster prevention cooperation project between Thailand and Japan. NEC conducted this trial as part of the “Research and study for the development of a flooding simulator in Thailand” project commissioned by Japan’s Ministry of Internal Affairs and Communication.

In April 2015, Japan’s Ministry of Internal Affairs and Communication and Thailand’s Ministry of Information and Communication Technology issued a joint statement announcing that the two countries would cooperate in a wide range of areas, including the development of more sophisticated disaster prevention ICT and the use and application of the technologies.
