The Rench is a right tributary of the Rhine in the Ortenau ( Middle Baden ) coming from the Black Forest .

Surname

The Rench was mentioned in 1291 as rivus Reineche . Albrecht Greule sees an Indo-European root * reg- with the basic meaning “to be moist”.

course

The Rench rises on the southern edge of the northern Black Forest at Kniebis near Bad Griesbach in the Black Forest . The Schöngrundbächle rises at around 915  m above sea level at the source furthest from the mouth of the Refuge district of the Black Forest community near the former youth hostel . NN , which, after passing through its steep slope , flows together with other streams first to the Alten , then to the Wild Rench , which is only called Rench below Bad Griesbach . The Rench runs altogether in a distinctive south curve through the Middle Black Forest and, crossing the hilly Ortenau fruit and wine-growing region, emerges into the Rhine plain. After almost 57 km it flows at Rhine km 314.8 between Helmlingen ( Rheinau ) and Lichtenau without separating strip of land next to the Mühlbach in the Rhine .

The Rench flood canal was built between 1936 and 1953 for the Acher-Rench correction to divert floods . It branches off from the Rench at Erlach , takes up the Acherkanal at Rheinau and reunites with the actual Rench at Memprechtshofen .

Valley landscape

The upper Renchtal around Bad Peterstal-Griesbach is initially cut into wooded red sandstone plateaus and turns into a more open, very restless and steeply relief valley landscape, the center of which is the small town of Oppenau . There the Lierbach, known for its waterfalls, flows from the right . In Lautenbach , the valley suddenly widens into the foothills zone with the town of Oberkirch at the foot of vineyards and the small town of Renchen , whose surroundings are characterized by fruit growing.

The B 28 leads through the Renchtal , an important Black Forest crossroad that connects the Strasbourg area with the upper Neckar area. Above Bad Griesbach it leads steeply and serpentine up to the Alexanderschanze (968 m). The Renchtalbahn runs from Appenweier to Bad Griesbach . It also contributed to the development of the spa in the Renchtal, which began in Bad Griesbach in the 16th century and which soon expanded to Bad Antogast near Oppenau (especially high nobility), Bad Peterstal and Bad Freiersbach (now Bad Peterstal-Griesbach).
