Continuous Monitoring and Adaptive Control (CMAC) is a category of stormwater Best Management Practice (BMP) that allows for a wider range of operation of detention and retention ponds. CMAC systems typically consist of a water level sensor, an actuated valve, and an internet connection.
Specific applications of CMAC include flood protection, water quality treatment, water reuse, and channel protection.
