Delineation of watersheds
Under FP6 CCM developed a first version of a European-wide river and catchment database for future use in environmental modeling activities. The database corresponds to a mapping scale of roughly 1:250 000 to 1:500,000, depending on the region.

Conclusions

JRC Ispra - IES
A lot of data but not too much measurements
A lot of estimated data by PTFs
For the moment, there is no harmonization of measured data. This will come from Biosoil study (measurements will be finished in August 2008) but it represents only 10% of the whole plots
