The city of Angkor, capital of the Khmer empire from the 9th to 15th century CE, is know for its impressive temples and rich heritage of water management. The Angkor Archaeological park site in Cambodia was added to the UNSECO World Heritage list in 1992. It includes the temple of Angkor Wat, Bayon temple at Angkor Thom and the networks of barays and canals created over the centuries by the Khmer kings. Recent research has uncovered an extensive channel network stretching across over 1000 km2. The channel network with large reservoirs (termed barays) formed the structure of the city and was the basis for its water management. The winter school will graphically summarize and document through a coffee table book with rich Angkor water management heritage and lessons that might apply to present challenges in planning and managing water resources or human habitats.
