PROPOSAL OF MERIT DEM CORRECTING METHOD USING LiDAR DATA AND ITS APPLICATION TO FLOOD RISK ASSESSMENT OF TEMPLES IN METROPOLITAN THAILAND

Key Points

• To assess the usability of temples during floods in Bangkok, Ayutthaya, and Nonthaburi in Thailand.
• Developed MERIT DEM-Thailand using LiDAR data to correct vulnerabilities.
• Evaluated flood hazard and occurrence probability based on elevation.
• Employed binomial distribution for calculating flood occurrence probability.
• High-risk temples were predominantly in Ayutthaya.
• Bangkok and Nonthaburi had a higher proportion of low-risk temples.
