摘要: An integrated model system has been implemented for downscaling from climate models, to wave and continental shelf models tides surge, coastal waves water levels overtopping of sea defences inundation. Within the system, 3rd generation TOMAWAC is applied transfer inshore toe seawall, producing input predictive tool EurOtop that provides estimates rates. This coupling then used assess sensitivity predictions uncertainty in offshore hydraulic conditions beach a case study on 7th November at Walcott East Anglia, UK. The methodology towards nearshore allows estimation induced errors heights by introducing small changes level significant height. Wave height leads an error discharge rate less than 30 %. Errors are much higher. A + 10 % could increase nominal factor 2.7. Thus, least this particular case, mainly sensitive level. Uncertainty profiles also investigated showing low levels.
