Hypothetical System

A numerical model is presented, capable of computing drawdowns anywhere in a multiaquifer/aquitard system, resulting from pumping from a single well, screened in arbitrarily chosen aquifer(s) in the system. The model is of radial, symmetric type, in the sense that inhomogeneities in horizontal directions cannot be taken into account. The model was created primarily to compute the effects of any kind of stratification in an aquifer system on the results of pumping tests. The computing principles are described, and drawdowns in a hypothetical system are computed to be compared with standard aquifer test formulas in order to illustrate the behaviour of the system. The model is finally used for interpretation of two earlier reported aquifer tests from localities in Denmark.

Good Agreement

The numerical model is developed consisting of a 1D flow model and the morphological model to simulate the erosion due to the water overtopping. The step method is applied to solve the water surface on the slope and the finite difference method of the modified Lax Scheme is applied for bed change equation. The Meyer-Peter and Muller formulae is used to determine the bed load transport rate. The model is calibrated and verified based on the data in experiment. It is found that the computed results and experiment data are good agreement.
