The Archaeological Survey of India, in collaboration with the National Authority for Preah Vihear (NAPV), has enlisted national experts in hydrology and geology to study systems at Preah Vihear Temple.

Their goal: understanding rainfall impact and topographical changes to safeguard the ancient structure.

NAPV director-general Kong Puthika disclosed on January 9 the collaborative effort with national experts. This research, integral to temple conservation, delves into potential damage and rainfall effects on the temple, built in the 11th century atop a 525m in the Dangrek Mountains, in Preah Vihear province. 

A crucial aspect involves addressing irrigation challenges to redirect rainwater away from the monument’s infrastructure.

Puthika highlighted the geology research, noting the foundation’s role in supporting the temple for centuries. With observed cracks and breakages in mountain stone layers, understanding these changes becomes pivotal to prevent potential impacts on the temple. 

“So, with this hydrological study, we aim to figure out the yearly rainfall volume on the temple. This will help us devise measures to shield the temple infrastructure. On the geology front, we’re examining shifts in topography. This gives us an idea regarding potential risks, guiding us to find ways to prevent any impact on the structure,” he explained.

He said that they have so far explored the area for three days, gathering stone samples and compiling rainfall-related documents. These were then taken to a lab for analysis, where they’ll assess rainfall, water flow from the area of the fifth gopura – an entrance tower – and changes in topography and the stone foundation. 

“After we take the samples to the lab, they will be able to gather additional ones. So, we expect results from the samples within the next three to six months,” he said.

He said that once the results are available, the NAPV will create a more detailed document and work on restoring the monumental fifth tower based on UNESCO’s recommendations.
