The purpose of this study is to propose a procedure to predict groundwater behavior under new boundary conditions based on previous observations and on prior geotechnical and geological information. Also, special emphasis is given to the quantification of the uncertainties that are present in every stage of the procedure. First, the model parameters are estimated with involved estimation errors based on observations and the prior information by following an inverse analysis procedure. Second, the information obtained is used as input to predict the future behavior of the groundwater by introducing a stochastic finite element procedure. The final outcome of this procedure is the prediction of ground water under new boundary conditions with quantified uncertainties involved in it. A rather simple numerical example is attached to illustrate the results.
