Mechanism Analysis of Quasi Synchronous Changes in Water Level and Water Temperature in Tongliao Earthquake Observation Well in Inner Mongolia
Using regional hydrogeological data,water temperature gradient test results,regional groundwater exploitation data,and precipitation data,the factors affecting the multi-year and interannual changes in water level and temperature in the Tongliao earth-quake observation well in Inner Mongolia were analyzed.On this basis,a hydrodynamic geological model was constructed to explore the mechanism of quasi synchronous changes in water level and temperature in the well.The results indicate that regional groundwater extraction and rainfall are the main influencing factors for the quasi synchronous changes of water level and temperature in the well,and the cold water infiltration theory can well explain these quasi synchronous changes.
