Abstract: Stop log gate intake, multi-level orifice intake, and floating point intake, are often used as engineering measures on thermally-stratified reservoirs to control the temperature of irrigation water for crop growth. Previous studies on temperature of water released from such intakes, particularly comparative studies of different types of intakes, are lacking. This study has conducted experimental tests to model the thermal stratification of a reservoir and compare these three intakes. Results show that the released temperature of stop log gate intake is higher than that of the other two intakes and of all the intakes, the released temperature are closely related with their submergence but nearly irrelevant to their flow rate. This study would lie a basis for selection, operation, and management of reservoir water intakes.
