Data — Watercourses to be preserved first — SAGE Ill Tablecloth Rhine — 2013

Rivers to be preserved as a priority on the perimeter of the SAGE ILL NAPPE RHIN. Rivers closely related to the Rhine water table (ground watercourses or predominantly groundwater streams) and/or very low flow rates are particularly sensitive to discharges and removals. These are prohibited by SAGE ILL NAPPE RHIN (cf. Article 6 of the Regulation). Sampling should preferably be done in the water table, close to the surface of the soil in general at a depth of tens centimetres) in the groundwater stream areas. Discharges will be directed to streams with sufficient self-treatment capacity.
