A dirichlet method for the computation of tri-dimensional subsurface flow problems involving more than one well Original Research Article

Usually the modelisation of groundwater flow from different wells in an aquifer is done by applying a Neumann boundary conditions on the borehole walls where a distribution of flux is chosen a priori for the system and not according to a sound knowledge of the real situation. A possible way to circumvent this problem is to use the Dirichlet method. This method that has proved itself to be quite efficient in different studies is, however, subject to the severe restriction that it is only applicable to situations where the pumping activity arises from a single borehole. In this work, this constraint is removed and a Dirichlet method applicable to situations where an arbitrary number of wells are simultaneously pumped is presented.
