Short summary
We present a model parameter sensitivity and uncertainty analysis of the Delft3D model for the simulation of storm hazards. The sensitive model parameters include wind drag, depth-induced breaking, and bottom roughness. Several parameters show no sensitivity and can therefore be excluded to reduce the computational overburden of probabilistic surge hazard estimates. A comparison of the model performance with forcings from three different wind models is also presented.
