This layer shows the European catchments and RIvers network System (Ecrins), http://projects.eionet.europa.eu/ecrins . It is a fully connected system of watersheds, rivers, lakes, monitoring stations, dams, made from the JRC CCM2.1 and many other sources. Compared to CCM, ECRINS offers a smaller number (138,000 instead of >2,000,000) of elementary catchments which average size is 92km2. Only the main drainage system, nevertheless comprising ~ 1.4 million km of rivers has been kept.
