Today the Flood Risk Management Plan for Riga City was ratified in the Riga City Council meeting. With the ratification of this document, the work on the implementation of the main activities of LIFE+ co-funded project “Riga Against Flood” can be considered completed. All the substantial research, carried out within the framework of the Project, will remain at the disposal of Riga City Council City Development department, who will use this documentation in their further work with city planning issues. All the Project’s materials – research, presentations, maps, publications and other documents will be available on the Project’s homepage for the next five years.

On September 28, this year, the closing conference of the Project "Riga Against Flood" was held. The participants of the conference were informed about the course of the Project, research done within the framework of the Project and its results, as well as the documents developed during the course of the Project – Flood Risk Management Plan for Riga City and Methodological Guidelines for territorial planning in flooding territories. The guests of the conference – experts from Hamburg and Helsinki – shared with their experience in flood management issues.

Within the framework of the Project “Riga Against Flood” the development of one of the main components of the Project - “Methodological Guidelines for Territorial Planning in Flooding Territories” – has been completed. The development of the Guidelines was based on the obtained information and results of research carried out within the framework of the Project. Guidelines for territorial planning in flooding territories are unique due to the fact that this document is the first of its kind not only in Latvia, but also in the Baltic States.

NASA's water level rise map

Is this NASA model really accurate?

Firstly, the model knows nothing about the tides. Since tidal variation can be 10m or more in some parts of the world, this is a major deficiency.
Secondly, the NASA data itself is not very accurate. Jonathon Stott has said that “NASA claims their height data is accurate to +/- 16m with 90% certainty”. NASA gathered the data by radar from orbit, so buildings and trees cause a systematic overestimation of the elevation of built-up and forested areas.
Thirdly, the NASA data does not extend beyond +/-60 degrees latitude. Its accuracy becomes degraded at the extremes of its range, especially in the Southern hemisphere.
Fourthly, the simulation takes no account of the effects of coastal erosion.
Fifthly, It doesn`t take any account of coastal defences. It’s obviously possible to build defences that protect habitable land far below sea level. Current defences (in Holland) are able to withstand an extra +1 metre of mean sea level.
Finally, there are areas of the world far from the oceans that are far below sea level. These areas are shown as flooded on my map, where clearly they are not in danger. The area North of the Caspian Sea is the most striking example.
