Abstract

Coastal zones have large social, economic and environmental values. They are more densely populated than the hinterland and concentrate large economic assets, critical infrastructures and human activities such as tourism, fisheries, navigation. Furthermore, coastal oceans are home to a wealth of living marine resources and very productive ecosystems. Yet, coastal zones are exposed to various natural and anthropogenic hazards. To reduce the risks associated with marine hazards, sustained coastal zone monitoring programs, forecasting and early warning systems are increasingly needed. Earth observations (EO), and in particular satellite remote sensing, provide invaluable information: satellite-borne sensors allow an effective monitoring of the quasi-global ocean, with synoptic views of large areas, good spatial and temporal resolution, and sustained time-series covering several years to decades. However, satellite observations do not always meet the precision required by users, in particular in dynamic coastal zones, characterized by shorter-scale variability. A variety of sensors are used to directly monitor the coastal zone and their observations can also be integrated into numerical models to provide a full 4D monitoring of the ocean and forecasts. Here, we review how EO, and more particularly satellite observations, can monitor coastal hazards and their drivers. These include coastal flooding, shoreline changes, maritime security, marine pollution, water quality, and marine ecology shifts on the one hand, and several physical characteristics (bathymetry, topography, vertical land motion) of coastal zones, meteorological and oceanic (metocean) variables that can act as forcing factors for coastal hazards on the other hand.

Abstract

Fifteen years after the launch of ERS-1 and TOPEX/POSEIDON, the European Space Agency, in collaboration with the French Space Agency, CNES, is organising an exceptional Symposium on "15 Years of Progress in Radar Altimetry", in Venice, from 13 to 18 March 2006. This unique event will create the opportunity to look back and analyse the progress made since the launch of ERS-1, characterise the difficulties, learn from the ones overcome and focus on the unresolved issues. This Symposium will host a very rich Hydrology session which will acknowledge the important progress recently made in radar altimetry retrieval algorithms. This permitted the reprocessing of data since the launch or ERS1 and offers to the non-specialist of radar altimetry a surface water level time series up to 15 years long, globally. Furthermore while large remote basins have very few, and often inaccurate or incomplete observations available to validate models, these times series are being used to better understand the strengths and weaknesses of hydraulic models, as well as the limitations of such data series. Requirements for the future altimetric missions, in particular the Water Elevation Recovery mission (WatER) proposed to ESA by an international team, are scheduled to be presented and discussed in a special session followed by a round table session.
