Detailed explanation-1: -A river lift system pulls water immediately from rivers to help with irrigation. River lift systems depend on pumps and direct fetching rather than the overall flow of water from rivers via canals. In areas where canal flow is inconsistent given limited reservoir outflow, a river lift system is used.
Detailed explanation-2: -Requirements of Lift Irrigation System (LIS) Water Source-Suitable and constant water source should be available for whole year at the site of LIS. Water can be made available through Dams, Weir, River canal etc. Lifting Medium-To lift water to the desired location, lifting medium i.e. pumps are required.
Detailed explanation-3: -The lift irrigation method is used both for watering of a certain area as a whole and for water application to particular elevated sites in the area of gravity irrigation (at that water is lifted from river or from irrigation canals).
Detailed explanation-4: -In regions where canal flow is uneven due to limited reservoir outflow, the river lift system can be used.
