Step 1: Concept Comprehension:
The query requires identification of the water source for the royal sector of the Vijayanagara capital, a meticulously designed complex featuring numerous palaces, audience halls, and temples.
Step 2: In-depth Analysis:
The Vijayanagara rulers engineered an advanced hydraulic infrastructure for managing water for both agricultural and urban consumption.
The Hiriya canal, a major watercourse, sourced water from a dam on the Tungabhadra river, primarily serving agricultural irrigation.
The Kamalapuram tank, a substantial reservoir situated south of the royal center, was vital for the urban water supply. Archaeological findings confirm the existence of channels originating from this tank to convey water into the royal center. This water supplied various reservoirs, bathing facilities (such as the Queen's Bath), and gardens within the elite precinct.
The Lotus Tank is likely a minor decorative reservoir, receiving water rather than being a principal source for the entire center.
Step 3: Conclusion:
Water from the Kamalapuram tank was specifically directed to fulfill the requirements of the royal center in Vijayanagara.
