In this project we want to determine uncertainties in subsurface flow and solute transport modeling, which are due to the heterogeneity of the soil parameters. By applying stochastic finite element methods to selected flow and transport problems, the probability distributions for pressure and concentration will be calculated numerically. From the probability distribution we can derive transgression probabilities, which are important for risk assessment. We will consider flow conditions which are close to reality, such as flow in bounded domains. Soil parameter fields with complex probability distributions will be considered.
