The emerging temperature tracer method has its own unique advantages in accurate calculation of the amount of hydrodynamic exchange in the hyporheic zone, which is always a challenge. On the basis of introducing temperature tracing theory and calculation methods, we calculate the amount of hydrodynamic exchange in the hyporheic zone of the Dakepo Lake as a case study. Results show that during the monitoring period, the magnitude of flow velocity that groundwater recharges lake is between 0~2cm/d, and the amount of total exchange is 2.35cm. In addition, by comparing with the results of hydrodynamic method, we can see that the results of the two methods are close, which indicates that the temperature tracer method has good accuracy for the calculation of pore water flow velocity, and is suitable for the accurate calculation of hydrodynamic exchange capacity in the hyporheic zone.
