The Khmer Empire's hydraulic networks, including barays, were primarily built to support which activity?
Correct Answer:
Irrigation and flood control to support agriculture.
Explanation:
Water management for farming is what the Khmer hydraulic networks were designed to do. Barays were massive artificial reservoirs that captured monsoon rains and fed a vast system of canals to the rice fields, allowing irrigation during dry periods and storage during floods. This irrigation and flood control made it possible to grow large amounts of rice and support a substantial population around Angkor. While canals could serve other roles, the primary purpose was sustaining agriculture through reliable water supply, not defense, religious ceremonies, or transportation.
