The Impacts of Water Transfer on Thermal Structure of Shallow Reservoir

A two-dimensional numerical model was built for the typical shallow reservoir with serious thermal pollution in the North China Plain. After calibration and validation, four scenarios were developed to study the impacts of water transfer on thermal structure. Model results showed that the hydrodynamic and water temperature could be well simulated. The effects of water transfer on thermal structure showed in decreasing temperature rises, which was more remarkable for regions far away from the releasing point of thermal discharge. In terms of reducing temperature, 45.5 m3/s was the most efficient inflow rate among the four representative flow rates. This study provides useful information for reservoir sustainable management.
