colmatage

Colmatage refers to the clogging or blockage of a surface, such as a water collector or filter, caused by the accumulation of debris, sediments, or biological growth. This buildup can reduce the efficiency of systems like rainwater harvesting tanks, reservoirs, or drainage channels by preventing water from flowing freely. Over time, colmatage may require cleaning or maintenance to restore proper function. It is a common natural process that can be influenced by environmental conditions, and managing it is essential for ensuring the longevity and effectiveness of water management systems.
