ECRINS is not the name of a mountain massif, but refers to the EEA Catchments and Rivers Network System.

This mapping project, led by the European Environment Agency (EEA) consists of a series of maps, presented in different layers meaning that they can therefore be superimposed one on top of the other, with the aim of gaining a better understanding of the hydrological characteristics of European subsoil.

Lakes, dams and crevices are represented on the maps, as are treatment plants and equipment for water management, to provide a detailed and comprehensive view of the European hydrological situation, from Iceland to the Persian Gulf.

These maps are designed to be used as a tool for decision-makers and to fuel the development of local and European policies to improve our understanding and management of water. They will be made available for consultation to everyone via a specific piece of software, SIG, which provides users with access to the various layers of these maps in order to obtain information regarding specific subjects, such as the delineation of river basins. It is also possible to combine several layers to cross-reference data and be able to respond to cross-cutting issues such as the water balance of a particular basin. Since this project is aimed at a specialised audience, it requires advanced knowledge of cartography and hydrology in order to be fully understood.

The European Environment Agency (EEA) is an agency of the European Union, whose mission is to provide reliable and independent information for all those who participate in updating, adopting, implementing and assessing environmental policy, as well as for the wider public. At present, the EEA has 32 member states.

The entire project is available for consultation here.
