Following the flood in 2011, the historical monument sites of Ayutthaya were also affected and damaged, the threat posed to cultural heritage by flood disaster analysed for six zones in Ayutthaya, Thailand. The vulnerability of 84 historical monument sites has been evaluated through a conservation calculation based on the approach conducted is based on previous study and application of Geographic information system (GIS) techniques for identifying the disaster vulnerability areas and the priorities conservation. For the present study, this adapted approach was chosen because it allows the non-experts in the field of urban cultural heritage or architecture conservation, to perform survey on the step of conservation. Moreover, the results of GIS can be verified with the field survey to deliver priorities of intervention based on the vulnerability of the historical monument sites, physical factor that are considered important for the occurrence of flood disaster have been used to generate a susceptibility map. A qualitative risk assessment was carried out by combining susceptible area and historical monument sites. As there were very limited historical damage data available on the occurrence of flood disaster, a combination of local and expert knowledge has been used to extract information on both historical monument sites. Finally, some recommendations are given related to the analysis of the impact of natural hazards on historical monument sites and assets for evaluate the risk factors of integrating hazard risk aspects of cultural heritage sites into the conservation plans.
