A thermocline (also known as the thermal layer or the metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below. In the ocean, the thermocline divides the upper mixed layer from the calm deep water below.

During a water temperature stratification period of the tributary bay, fluctuation is generated from letdown flow, and water level of a reservoir fluctuates, so that tide is formed at the estuary of the tributary bay. Tide type inflow and outflow are formed between the bay and a trunk reservoir and have shear effect at the thermocline, so that tide interval wave is generated near the thermocline. Water of the thermocline flows reversely since the tide internal wave transmits along the thermocline, so that alternate flow is generated, water temperature fields are mixed, and then water temperature stratification is improved. Deepwater reservoir equal-density stratification water is aroused to generate internal wave under reservoir regulation, andthus natural underwater stirring movement is formed.

According to the scheme, the flow equalizing baffles are arranged in the water distributors, so that the water distribution area is increased and the water flow speed is reduced and is more uniform to achieve an effect that static stratification of pool water is realized according to water temperature; meanwhile, the water pool is partitioned into a plurality of small water distribution systems by the partitioning falling-curtains to form a similarly honeycomb structure, so that transverse interference of the water pool is greatly reduced, and meanwhile, the pool water is more finely controlled; the thickness of a thermocline is reduced as much as possible by the scheme, so that the space requirement of the water pool is greatly reduced; and the thickness of the thermocline is compressed to be 5-10 cm, so that the utilization efficiency of the energy storage pool is increased, the energy efficiency of the energy storage system is improved, and the effects of energy conservation and environmental friendliness are achieved.
