Simulación de la recarga artificial de un acuífero en su manantial. Aplicación al manantial de Vozmediano (Soria)

Abstract

The papers approaches the management of an aquifer jointly with the springflow feeded by it. The well known solution by Rorabaugh (1963) for a one-dimensional homogeneous aquifer of finite length and the SIMERO model (Degallier, 1972) is used, so a very simple solution for the aquifer outflow due to a series of instantaneous discrete artificial recharges uniformly distributed along the aquifer is obtained. Only a few components of the infinite terms of the analytical solution are used. The are the first Fourier components of the sinusoidal eigenfunctions that solve the problem. As the eigenvalues of the solution are (2n+1)²⋅α, the factor to be applied to each components is exp [-(2n+1)^2α⋅t] that decays very fast with time for high values of n. So understood, the structure of the solution can be perceived as an extension, with several cells, of the simple approach of the unicellular model.
The purpose of this modeling approach is to study the management of the Vozmediano spring for an average year, taking advantage of the aquifer inertia.
