Oad3200113Four water courses recorded the loss of water before improvement as 25.58, 13.82, 36.46 and 39.84%, however after improvement these losses exhibited reduced values i.e. 1.61, 1.36, 1.63, and 1.36, and conveyance efficiency improved by 37.85%. Therefore it is recommended that to obtain maximum conveyance efficiency and reduced water loss risks the lining of water courses should be on top priority.]]>Bridley, S.F.,1987Corey, G.L. and W.
