Eurowaternet and Waterbase

Eurowaternet is designed to give a representative assessment of water types and variations in environmental pressures caused by human activity across Europe. It is based on sample stations in existing national monitoring networks and programmes. The need for comparability (comparing like with like) is achieved with a statistically layered design. Each defined layer contains similar water bodies. The use of the same criteria for selecting layers and water types across the countries ensures the basis for valid status comparisons.
