| Zusammenfassung |
| Storm surges and their associated coastal inundation are major coastal marine hazards, both
in tropical and extra-tropical areas. As sea level rises due to climate change, the impact of
storm surges and associated extreme flooding may increase in low-lying countries and
harbour cities. Of the 33 world cities predicted to have at least 8 million people by 2015, at
least 21 of them are coastal including 8 of the 10 largest. They are highly vulnerable to
coastal hazards including storm surges.
Coastal inundation forecasting and warning systems depend on the crosscutting
cooperation of different scientific disciplines and user communities. An integrated approach
to storm surge, wave, sea-level and flood forecasting offers an optimal strategy
for building improved operational forecasts and warnings capability for coastal
inundation.
The Earth Observation (EO) information from satellites has demonstrated high potential
to enhanced coastal hazard monitoring, analysis, and forecasting; the GOCE geoid data can
help calculating accurate positions of tide gauge stations within the GLOSS network. ASAR
images has demonstrated usefulness in analysing hydrological situation in coastal
zones with timely manner, when hazardous events occur. Wind speed and direction,
which is the key parameters for storm surge forecasting and hindcasting, can be
derived by using scatterometer data. The current issue is, although great deal of useful
EO information and application tools exist, that sufficient user information on EO
data availability is missing and that easy access supported by user applications and
documentation is highly required. Clear documentation on the user requirements in
support of improved storm surge forecasting and risk assessment is also needed at the
present.
The paper primarily addresses the requirements for data, models/technologies, and
operational skills, based on the results from the recent Scientific and Technical Symposium
on Storm Surges (www.surgesymposium.org, organized by the WMO-IOC Joint technical
Commission for Oceanography and Marine Meteorology, JCOMM) and following activities,
that have been supported by the Intergovernmental Oceanographic Commission (IOC)
of UNESCO through JCOMM. The paper also reviews the capabilities of storm
surge models, and current status in using Earth Observation (EO) information for
advancing storm surge application tools, and further, for improving operational
forecasts and warning capability for coastal inundation. In this context, the plans and
expected results of the ESA Storm Surge Project (2010-2011) will be introduced. |
