| Zusammenfassung |
| When we want to forecast contaminant spreading or make a groundwater environmental risk assessment, knowing the source of the contamination is important. In this work, we have applied the ensemble Kalman filter (EnKF) to the simultaneous characterization of hydraulic conductivities and identification of contaminant source information including source location, initial release time, release duration, and release concentration by assimilating both piezometric heads and solute concentrations. A test in a synthetic confined aquifer is carried out. The results prove that EnKF is capable of simultaneously identifying hydraulic conductivities and source information by assimilating a sufficient amount of state variable measurements. |
