An interesting though unexpected finding of this work was the discovery of a leak in the Woolston Tidal Barrage. The model calibration was excellent in the lower estuary and in the Avon / Ōtākaro. However there was a strong anomaly between the modelled versus observed salinity datasets for the Heathcote / Ōpāwaho that have been influenced by the tidal barrage leakage. Read more about it here in the Brian Mason Trust report on 'Development of a fine-scale salinity model for the Avon Heathcote Estuary Ihutai'.
