The construction of models which involve the identification of parameters, such as groundwater models, often leads to numerical instabilities. Errors induced by these instabilities may actually increase with improved data collection and model resolution. It is, therefore, important to understand properly the origin and nature of such instabilities, and to allow for their effect. There are important differences between the problems of identifying parameters or inputs of a hydrogeological system from output observations, and the problem of simulating future outputs for given inputs and parameters. These have implications in the construction of algorithms for their solutions.
