The European Environment Agency (EEA) has been developed the Catchments and Rivers Network System (ECRINS) version 1.1. The ECRINS is the hydrographical system currently in use at the European level as well as widely serving as the reference system for the Water Information System (WISE) (EEA,2012). The current version of ECRINS is based on previous work carried out by the Joint Research Centre (JRC) Catchment Characterisation and Modelling (CCM) and the EEA (European Lakes, Dams and Reservoirs Database (Eldred2), European Rivers and Catchments (ERICA)), (EEA,2012).
