    In the framework of the project "753_09: Verbetering randvoorwaardenmodel" a calibration of the existing hydrodynamic NEVLA model of the Scheldt estuary – including all tributaries which are tidal dependant – is executed.
    In the reports ‘Verbetering randvoorwaardenmodel – Deelrapport 1: Gevoeligheidsanalyse’ (Vanlede et al., 2008a), ‘Verbetering randvoorwaardenmodel – Deelrapport 2: Afregelen van het Scheldemodel’ (Vanlede et al., 2008b) and ‘Vervolgstudie inventarisatie en historische analyse van slikken en schorren langs de Zeeschelde – Gevoeligheidsonderzoek 2D modellen’ (Ides et al., 2008) a sensitivity analysis and a first calibration of the NEVLA model of the Scheldt estuary were performed. In (Vanlede et al., 2008b) the calibration was performed for the calculated water levels and discharges, based on the phase and magnitude of the most important harmonic tidal components of these parameters. The model was calibrated for the year 2006.
    The objective of this study is to extend the calibration of the NEVLA model. The resulting model parameters from (Vanlede et al., 2008b) are used in this study as the reference simulation. However, the methodology of analysis is different in this report. It is based on the comparison of phase and magnitude of the calculated and measured high and low water levels. The harmonic tidal components of the water levels are not considered. This extended calibration is mainly focused on the Upper Sea Scheldt and the tributaries Zenne and Dijle. Calibration is performed for June – July 2002 because more detailed input data was available for this period.
    As a result of the calibration, the accuracy of the model for high water levels and low water levels was improved for all stations along the Scheldt estuary except Vlissingen. The results for Vlissingen were accurate and did not require improvement.
