                    snapshot at the start of event. Computational requirements are high, need to rerun at speed. data inputted. Council should consider holding SWAN Model calibrated version in
                    SWAN is okay but Xbeach is harder to loop.                                                    platform for any of the taskforce or panel to use in case one group isn't available during

Technical           Regional Coastal Process Model needs to calculate refraction well and calibrate wave models Ensure Regional Coastal Process Model scope takes this into account.
