HYDROCOASTAL

Home | FAQ | Documents | Software | Products | Publications

HYDROCOASTAL is a project funded by ESA to maximise exploitation of SAR and SARin altimeter measurements in the coastal zone and inland waters, by evaluating and implementing new approaches to process SAR and SARin data from CryoSat-2, and SAR altimeter data from Sentinel-3A and Sentinel-3B.

New SAR and SARin processing algorithms for the coastal zone and inland waters will be developed and implemented and evaluated through an initial Test Data Set for selected regions. From the results of this evaluation a processing scheme will be implemented to generate global coastal zone and river discharge data sets. Case studies will assess these products in terms of their scientific impacts.
All the produced data sets will be available on request to external researchers, and full descriptions of the processing algorithms will be provided.

Latest news

Final HYDROCOASTAL Product
The Final HYDROCOASTAL Product is now freely available on request. It contains L2 outputs from the different candidate algorithms over 25 regions, L3 water level and L4 River Discharge time series for nineteen inland water regions.
A subset of the Initial Test Data Set is also available (for regions not covered by the Final Product).
Also a small coastal data set produced by isardSAT with their Coastal and Fully Focused SAR Processors is available.

Final Review: 12 September 2023
The Final Review was held as a hybrid face to face and online meeting at ESRIN, Frascati.

Highlights were

  • Presentation and Review of the HYDROCOASTAL Project
  • Presentation and Review of Impact Assessment Reports and the draft Scientific Road Map

Final versions of the project deliverables will become available on the documents page)

Acceptance Review: 28 & 29 June 2023
The Acceptance Review was held as a hybrid face to face and online meeting at ESRIN, Frascati.

Highlights were

  • Review Final HYDROCOASTAL Output Products and associated deliverables
  • Report Impact Assessment Case Studies

Impact Assessment Case Studies

In the final phase of the project a series of 14 Impact Assessment Case Studies were carried out, to assess the potential scientific impacts of the improved coastal and inland water products generated by HYDROCOASTAL.

The outputs of these studies are summarised in the HYDROCOASTAL Impact Assessment Reports and also contribute to the recommendations in the Scientific Road Map(see the documents page.)
