Characterizing Curvilinear Features Using the Localized Normal-Score Ensemble Kalman Filter

Figure 9

Piezometric head evolution for one of the observation piezometers (no. 21), the location of which is indicated in Figure 4. Results are shown for the prior ensemble and for the updated fields after assimilating the piezometric heads in the first 60 time steps (67 days) using the localized NS-EnKF. The circles represent the piezometric heads in the reference field.
