| Résumé : | This paper shows how we may evaluate in a hydrogeological context (i.e. with hypotheses and parameters commonly encountered in hydrogeology) the different coefficients introduced in the three-dimensional quasi-asymptotic equation found previously (see this issue). The evaluation is based on stochastic models developed in hydrogeology and based on field experiments. An analytical evaluation is made for a simple model of the velocity autocorrelation tensor. Numerical values of the coefficients are given. Next, we applied the model in planar geometry. Exact solutions of the quasi-asymptotic equation are shown in this case. In particular, we examined the differences between our model and the model of Williams in fractured rocks. We end this paper with an estimation of the validity limits of the model. |
