Groundwater discharge or recharge in aquifers can be obtained from the analysis of temperature profiles, a costefficient
method widely applied in hydrogeology. In this study we proposed a set of type curves that can be used
for estimating the vertical velocity flow, and have the potential to allow, in certain cases, the assessment of the
thermal diffusivity of the soil matrix. The solutions, represented graphically, establish the dependencies of the
basic parameters involved in the process: groundwater velocity, thermal conductivity, specific heat, aquifer
depth and harmonic temperature period. Using the non-dimensionalization technique, the mentioned parameters
were organized in dimensionless groups which are verified by numerical simulations. For the estimates of the
groundwater velocity, transient temperature-depth measurements or steady state amplitudes of the harmonic
oscillation were used as input data. In this last case, a particular type curve solution allows us to assess the depth
from which temperature oscillations have a negligible amplitude compared to the amplitude at the ground
surface. The resulting dependencies have been applied to estimate the groundwater velocity in real aquifers and
laboratory experiences.
