Effective water management is crucial for dam operations, particularly when it comes to preventing flooding and maintaining reservoir levels. The use of Programmable Logic Controllers (PLCs) has become a standard solution for automating water level monitoring and control in dams. By implementing PLC-based systems, operators can remotely control dam gates, pumps, and drainage valves, minimizing human intervention while ensuring the safety of the structure. This article explores the design and functionality of a PLC system used for automated dam gate control, including five alarm levels for early flood warnings and automated water flow regulation.
