The Rotbach is a 21.9 km long orographically right tributary of the Rhine in the northern Ruhr area , North Rhine-Westphalia ( Germany ).

geography

The brook rises as Vennbach east of Königshardt at an altitude of 64  m above sea level. NN . From here the brook first flows in a northerly direction. The Reinersbach flows south after 400 m. When you reach the urban area of Bottrop , the stream is called Ebersbach . Below the mouth of the Pötteringsbach , the course turns to the west. From here on the stream is now called Rotbach . On its further course the brook flows through Dinslaken , before it south of Möllen at 19  m above sea level. NN flows into the Rhine.

The Rotbach overcomes a height difference of 45 m on its 21.9 km long path, which corresponds to a mean bed gradient of 2.1 ‰. It drains a 51.564 km² catchment area in the area of ​​the cities of Voerde , Dinslaken , Bottrop and Oberhausen .

history

The Rotbach is also called Munne, Münne, Minne, "die Bach", "die Beeck", "die Becke" or "die rothe Bache" on older maps. In a document from 1486 he is called "de roje Beek". Later it was also called "electoral Möhlenbach" or just Mühlenbach.

There are five known watermills on the Rotbach:

  • Grafenmühle (no longer available)
  • Watermill at Haus Hiesfeld
  • Dörnemann-Mühle near the village church Hiesfeld (no longer available)
  • Old town mill on the old market in Dinslaken (no longer available)
  • Watermill at the house apartment near the Rhine

At the beginning of the 20th century, the Rotbach was channeled over a long stretch.

environment

Long stretches of the Rotbach are exposed to subsidence resulting from underground hard coal mining at the Lohberg-Osterfeld mine .

On November 18, 1973, the north-west oil pipeline broke early in the morning and around 60,000 liters of crude oil flowed into the Rotbach via Franzosenstrasse. Oil barriers and the extraction of the oil were carried out by 150 firefighters.

On May 5, 1991 at 7:20 a.m. north of the Rotbach, west of the Dinslaken-Nord motorway junction, the Rhine-Main pipeline leaked due to subsidence . About 280 m³ of petrol flowed into the ground and the Rotbach. A fish death was triggered, but many other animals were also killed. Headaches, nausea and vomiting occurred in parts of the population and the auxiliary workers. Around 5,000 m³ of contaminated soil had to be removed and 300–400 trees cleared.

In order to prevent flooding of the stream, which was disturbed by subsidence in its receiving water, extensive construction measures were necessary in the 1990s, in the course of which a renaturation of the stream was sought. First, the course of the stream below the Rotbachsee was modified and a pumping station was built. In order not to allow the old stream integrated in the populated area to dry out, part of the pumped water now flows in the opposite direction. A later construction measure included the construction of extensive dykes above the Rotbachsee.

In the poor years of 2018 and 2019, the Rotbach dried up for months in many places.
