Storm surge scenarios for Hamburg

Abstract A scenario for future storm surge heights for the tide gauge of Hamburg St. Pauli is constructed on the basis of results from a regional model for Cuxhaven. Under the A2 emission scenario, an increase of the mean annual maximum water level of about 0.1724 m appears possible and plausible for the time horizon of 2030. In Cuxhaven, an increase of 0.14 may be expected in this scenario. In...

A CYCLONE INDUCED STORM SURGE FORECASTING MODEL FOR THE COAST OF BANGLADESH WITH APPLICATION TO THE CYCLONE `SIDR'

The coast of Bangladesh has a specialty in terms of high bending and many off- shore islands. Incorporation of the coastline and island boundaries properly in the numerical scheme is essential for accurate estimation of water levels due to surge. For that purpose a numerical scheme consisting of very fine mesh is required along the coastal belt, whereas this is unnecessary away from the coast. In...

Operational storm surge forecasting in the Netherlands: developments in the last decade.

The accurate forecasting of storm surges is an important issue in the Netherlands. With the emergence of the first numerical hydrodynamic models for surge forecasting at the beginning of the 1980s, new demands and possibilities were raised. This article describes the main phases of the development and the present operational set-up of the Dutch continental shelf model, which is the main hydrody...

Storm surge forecasting using Kalman filtering ( a review ) Report 95 - 99

Two data assimilation procedures for real time storm surge forecasting based on Kalman ltering are described. To reduce the computational burden of the Kalman lter, a time invariant lter approximation is suggested rst. This lter is computed using the Chandrasekhar-type algorithm. The resulting data assimilation procedure has been used for storm surge forecasting on a routine basis for a number ...
