Measurement of Vertical Groundwater Velocity from Temperature Profiles in Wells

摘要: Vertically moving groundwater transports heat by convection and causes curvature in the earth's thermal profile. Dimensionless plots of temperature distribution wells can be matched with published type curves to obtain solutions for vertical velocity, if conductivity solid-fluid complex is known or estimated. Rates upward movement through semiconfining beds determined from studies San Luis valley Colorado Roswell basin New Mexico were good agreement rates computed pumping tests water budget methods. Limitations method result instability borehole fluids, measurement detail required, magnitudes flow that detected.
