Confined aquifer slug test example#
This Inversion Test Problem demonstrates two solutions for the time-displacement response at a groundwater well resulting from the application of a single well falling head slug test. Both solutions describe the response for a fully confined aquifer. These are:
Cooper-Bredehoeft-Papadopulos (1967) solution
Hvorslev (1951) solution
These solutions assume full aquifer penetration by the tested well. All solutions are calculated in the Laplace domain and are inverted to the time domain numerically using the De Hoog et al. (1982) algorithm.

This example involves the matching of an appropriate forward model to time-displacement data obtained from a traditional single well slug test.
