This paper describes the development and results of a TELEMAC-2D hydrodynamic model set up to potentially provide an operational forecast of tides and storm surges for Tralee and adjacent bays, in South West (SW) Ireland. The TELEMAC-2D model was set up using the latest bathymetry data including high resolution multibeam and LiDAR data. The model was initially forced with TPXO tidal data and wind and pressure data from ECMWF and Met Éireann and calibrated against available gauge data in SW Ireland including Tralee Bay. The initial calibration of the model showed good agreement against the measurements, with the tide and storm surge model predictions, close to, or within the specified minimum target accuracy and forecast delivery times. Following the first of two trial periods in winter 2018/2019 the model boundary tidal forcing was updated to use FES2014, which resulted in closer agreement with tidal predictions. The second live trial period was subsequently carried out during the autumn of 2019. An analysis of the results shows that the hydrodynamic model is in good agreement with measurements. Little difference was observed between the storm surge forecasts using the ECMWF or Met Éireann meteorological forcing, but it was expected that the higher resolution Met Éireann Harmonie data has the potential to provide more detail. This paper summarises the development model setup and results to date.
