Resum
This work presents the analytical solution to the convolution integral by taking into account the most widely used lumped parameter hydrogeological models (Piston, Exponential, combined Exponential-Piston and Dispersion model) and the eight most typical input tracer functions (Constant; Sinusoidal with linear trend; Sinusoidal with combined sinusoidal and linear trend; Instantaneous pulse injection; Step or Heaviside; Instantaneous pulse with exponential ending; Long pulse with sharp ending; Lon...
