The HPC ReCaS infrastructure towards the simulation of subsurface hydrological processes

Well hydraulics concerns the process of flow toward/from wells, which occurs because of a vertical extraction or injection in the aquifer. The paper shows preliminary tests performed on the high performance computing (HPC) ReCaS infrastructure to compute simulations on the fluctuation of the water table in heterogeneous porous formation based on a stochastic parametrization of the transmissivity field of the aquifer for the horizontal flow around the pumping well. From a computational point of view, the more expensive aspects concern the storage of the samples and the numerical solution of the related boundary value problem. The numerical simulations were carried out by using packages/libraries included in the SCoPE toolkit v.3 available at the HPC ReCaS infrastructure.
