River course

The sour at Wœrth in Alsace

The Sauer ( Sauer French La Rivière, in the southern Palatinate headwaters Saarbach ) is a 70 km long left tributary of the Rhine in Germany ( Rhineland -Palatinate ) and France ( Alsace ).

Name

The name Sauer ( bach ) was used in südpfälzisch Alsatian - speaking world because of the creek in the headwaters led slightly sour -tasting water, that came from carrying in the source area moors. The High German name Saarbach built in the first half of the 19th century, when the Palatinate was newly mapped under the administration of the Kingdom of Bavaria and the Bavarian officials belonging locally pronunciation Sauerbach in the written language " translated ".

Geography

Course

The river rises as a green stream in western Wasgau, such as the southern part of the Palatinate Forest and the northern part of the Vosges is also called. The source is located at 310 m above sea level. NN height above the donkey walks just north of the German - French border between the municipalities Eppenbrunn and Ludwig angle. Immediately west of the Palatine main watershed from Erlenkopf ( 473 m above sea level. NN ) runs south to Rothenberg (415 m above sea level. NN ) in the north.

The green stream that flows two kilometers from southwest to northeast, bent at the confluence of the digester Bach right in southeastern direction and takes two kilometers to the left of the Stony Brook on. From here to the united waters named Saarbach. The so-called Saarbachtal runs about ten kilometers to the southeast, and the Saar river passes through the hamlet Schoental and Saarbacherhammer as well as the local church Fischbach. He Three kilometers further turns south and flows through Schönau and deer valley, where he crossed the German -French border to the northern Vosges down. From there on it is called sour.

Initially, further south, the acid flows through the Alsatian Vosges du Nord Regional Park, which includes the towns Lembach and Wœrth. In a left-hand bend to the southeast it reaches the Upper Rhine Valley, in which they Forêt de Haguenau flows 20 km far.

Hinterforst field it crosses under the Autoroute A35 and then turns to the northeast. It happened boiler village and leg home and opens at Seltz, where she still receives from the left the Seltzbach, in a western Altrheinarm. This, since its separation considered part of the oxygen from the Rhine, strikes north-east of Seltz in Munchhausen from the left on the Upper Rhine. On the German side, exactly opposite is the mouth of the coming of the Northern Black Forest Murg.

Hydrology

At the mouth of the acid into the Rhine, the average river discharge ( MQ ) is 6.07 m³ / s; the catchment area of ​​805.5 km ² here.

At the level leg home, the average annual runoff volume of oxygen was calculated over a period of 44 years ( 1967-2010 ). The catchment area corresponding to at this point 541 km ², about 67 % of the total catchment area of the river.

The highest water levels in the months of January - March measured. Your maximum level in the river discharge with 6.14 m³ / s in February. From April to the bed goes back slightly and reached its lowest level in September with 1.71 m³ / s to then to rise again from month to month. The average annual value is 3.72 m³ / s

The monthly mean discharge ( MQ ) the oxygen in m³ / s, measured at the hydrological station leg home, Data calculated from the values ​​of years 1967-2010

Nature

At the upper reaches of the Sauer both sides of the Franco-German border, in the Forêt de Haguenau and in the mouth region there are large areas that are largely natural and some even have jungle-like character.

The confluence of the Sauer ( Delta de la Sauer) is an extensive nature reserve, one of the six French Rheinau reserves. Located in the Delta de la Sauer Bois de Munchhausen is one of the last intact softwood in Central Europe. The White Willow stocks are covered throughout the year four to six months of water, which is relatively unusual for Central Europe. In the peripheral areas of the Bois de Munchhausen and higher gravel banks, the Hartholzaue developed. The mosaic of large-scale softwood and hardwood floodplain of marginal distinguishes the reserve naturelle du delta de la Sauer.
