Abstract
Identification of steady-state distributed systems with space-variable parameters is a crucial problem in aquifer hydrology. This problem is considered in a mathematical framework familiar to control engineers. Assuming a stochastic `random-walk' model for the parameter spatial variability, an optimal estimator is derived in the 1-D case, using a fixed-interval smoothing technique. An application to a numerical example demonstrates the effectiveness of the method. Some generalisation to nonlinear and 2-D cases are also discussed and an application to the identification of a real underground aquifer in Belgium is briefly reported.
