Composite clogging characteristics of emitters in drip irrigation systems

This study investigated the characteristics of emitter clogging substance in 16 kinds of drip irrigation emitters using 3 kinds of water sources that could typically induce composite clogging in the Yellow River irrigation area. The research results indicate that there was remarkable randomness in the behavior of composite clogging substances in a single emitter, and peak randomness ( Δ F_Q^t ) values were 19.5–20.8
