Towards reliable global allowances for sea level rise

Tide gauge data and information from tide, surge ocean models have been used to calculate validate the Gumbel scale parameters of extreme sea level distributions along world coastline. The inclusion model is found result in significantly improved correspondence between observed modelled that obtained using tide alone. so are shown be consistent with findings reported previously, such as assessments Intergovernmental Panel on Climate Change. However, considerably provision coast means coastal planners, others concerned impacts rise, can now undertake more complete investigations likely increase exceedance frequencies. In addition, engineers will access reliable estimates ‘sea allowances’ needed design defences for protecting populations.
