The hyporheic zone plays a crucial role in surface water and groundwater ecosystems,exerting significant influence on water supply,flood control,water pollution mitigation,and river ecological preservation.The application of heat tracer technology proves to be highly effective in investigating the hyporheic zone,allowing for the estimation of key parameters such as seepage ve-locity and effective molecular diffusion coefficient.Moreover,it facilitates the understanding of material and energy exchange pro-cesses within the hyporheic zone.Heat tracer technology boasts advantages such as straightforward device arrangement,environmen-tal friendliness,and prolonged observation periods.One critical aspect lacking in previous Chinese studies is the in-depth explora-tion of heat transfer mechanisms-the cornerstone of heat tracer theory.In this paper,the heat transfer mechanisms,highlighting variations in heat transfer modes across different rivers were discussed.A succinct overview of the heat transfer equation,detailing the evolution of analytical and numerical solutions in prior research was presented.Finally,the challenges and outline future direc-tions for the development of this technology were addressed.
