Conveyance losses account for _________ of water delivered into a canal

Conveyance losses can account for a significant portion of the water delivered into a canal, with figures often ranging from 20% to 40% or more, depending on the type of canal and maintenance. For unlined canals, losses are often higher due to seepage and evaporation, while lined canals experience lower losses. For example, one study reported that about 40% of the total water supply can be lost before it reaches the farm gate, notes the Technical Journal, UET Taxila.
