Canal hierarchy: Main Canal → Branch Canal → Distributary → Minor → Water Course (field channel). Main canal takes off from headworks; branch canals offtake from main; distributaries from branch (serve 40–2000 ha); minors serve villages; water courses take water to field. Each step reduces discharge.
