Damage data for heritage sites and structures
With GIS, determination of FAD assets in flood zones, assuming all sites and structures
would be affected to some extent.
Assuming that with the selection of 16 different types of cases found in and around
Ayuthaya, a baseline could be determined. A square meter value for restoration work
at the compound level as well as one for the constructions/building was determined,
allowing an extrapolation to other sites where damage evaluation was not yet
conducted.
This assumption was verified by comparing data from sites where damage estimates
were already provided by FAD, and on the overall this assumption holds, our numbers
being on the conservative side compare to FAD. However it is not a precise way to
determine the value of damages on a site by site basis and should not be use for this
purpose.
For community temples, we could not extrapolate from the numbers we received.
There was too much variation between them, as they were self-provided by
communities and religious organizations.
Damage data for the Repository of Heritage
A square meter value for restoration work of structures and another one for the
compound were determined by analyzing Chantharakasem National Museum, and
extrapolated to the museums with the relevant information (building size, compound
size).
Losses due to the lack of visitors
With 3 years of visitor data from the FAD and the Ministry of Natural Resources and
Environment, a baseline for the number of Thai/foreign visitor per quarter was
calculated.
We assumed that for the flood quarter (in our tables referred to as Q0 - the last Thai
quarter from July to September) the visitors would only be 5 percent of the regular
traffic of a regular quarter. We then assume that Thai visitors would be slower to
return to the sites compared to foreigners, with a recovery completed by the end
of the third quarter. (20%-20%, 30%-40%, 50%-70% of reference quarter visitors,
respectively for Thai/foreigners, for each of the three quarters)
