    Abstract

    Estuarine floods are one of the most harmful and complex extreme events occurring in
    coastal environments. To predict the associated effects, characterize areas of risk and
    promote population safety, numerical modelling is essential. This work performs a
    comparison and a combination of two 2-dimensional depth averaged estuarine models
    (based on openTELEMAC-MASCARET and Delft3D hydrodynamic software
    packages), to develop a two-model ensemble approach that will improve forecast
    robustness when compared to a one-model approach. The ensemble was applied to
    one of the main Portuguese estuaries, the Douro river estuary, to predict the expected
    water levels associated with extreme river discharges in the present-day configuration
    with the new breakwaters. This is a region that is periodically under heavy flooding,
    which entails economic losses and damage to protected landscape areas and
    hydraulic structures. Both models accurately simulated water levels and currents for
    tidal- and flood-dominated validation simulations, with correlation values close to 1,
    "RMSE" below 15%, small "Bias" and "Skill" coefficient close to 1. The two-model
    ensemble results revealed that the present-day estuarine mouth configuration will
    produce harsher effects for the riverine populations in case identical historical river
    floods take place. This is mainly due to the increase in the area and volume of the
    estuary’s sand spit related to the construction of the new breakwaters.
