Map — SRCE2014 — ALSACE — Information map n°6: Blue frame of the SRCE

This map was made to represent the elements of the blue frame of the SRCE as well as the main obstacles to flow at the scale of Alsatian territory. The components of the blue frame correspond to rivers classified under Article 214-17 of the Environmental Code, List 1 and 2 or watercourses important for biodiversity, to potentially mobile portion watercourses (no special treatment on all the fields of the GIS data cited). Mapped subtrames are predominantly wet areas: wetlands, open wetlands and wetlands. The obstacles to flow mapped come from a query on the “franchissability” field of the obstacles of the table. This mapping is carried out for a print planned in A3 format, color, portrait orientation.
