Improving characterization of hydrogeologic spatial variability for flow and transport models: a new method using geological and geophysical data

The usefulness of predictive simulations obtained by groundwater models is often hampered by the inability to indicate and quantify the reliability of model results. Uncertainty in model predictions primarily stems from a number of errors relating to the model formulations, such as inadequate concept and description of processes and interactions, inadequate sense of spatial and temporal variability, inadequate description of the state of the system (e.g., geometry, boundary conditions and stresses), and incorrect specification of parameters and associated error bounds. In recent years significant research has been carried out resulting in a variety of approaches that can be used to incorporate the information about these errors into the modeling process and to establish the level of uncertainty in model-based decision-making. Increasingly, these new techniques are being applied to a variety of problems and sites.
