Abstract: This paper describes the development of water temperature research from three aspects—influence factors, response mechanism of water temperature to dynamic loading and hydro-thermodynamic theoretical model. High-precision digital observation technology provides reliable and effective data support for the scientific research of well water temperature. Source of replenishment and hydrodynamic action are two major factors that affect the dynamic change of well water temperature. The source of replenishment determines the shape of the vertical distribution curve of the temperature of the well and aquifer system. Hydrodynamic action determines the amount of groundwater recharge and the speed of groundwater flow in the aquifer, thus affecting the temperature change of the well-aquifer system. And the dynamic loading affects the flow speed of water within the well-aquifer system and changes the water temperature. Through the summary of the study on the factors influencing the water temperature of the well and the formation mechanism of water-thermal dynamics, it is helpful to clarify the relationship between the water temperature of the well and the aquifer, and provides an important research method for the quantitative analysis and mechanism interpretation of the water temperature of the well.
