Aquifer parameter estimation by extended Kalman filtering and boundary elements

摘要

The extended Kalman filtering (EKF) method is used as an automatic calibration procedure for the estimation of hydrogeological parameters based on ground- water head observation. The numerical tool employed is the dual reciprocity boundary element method (DRBEM). Numerical results for steady and unsteady flow in heterogeneous aquifers have demonstrated the potential of this combined procedure for groundwater applications.
