Rotbach (Erft)

Rotbach in Lechenich

The Rotbach ( called the upper reaches Nöthener Siefen, closing creek, mill creek or Bruchbach ) is a 39.1 km long, orographic left-sided or southwesterly inflow of Erft in the western part of North Rhine -Westphalia ( Germany ).

Course

The Rotbach arises as Nöthener Siefen in the Eifel mountains and passes through the Rhineland. Its source is at the southeastern edge of the Kermeters, a northern part of the Eifel, between Kall - Wallenthal the southeast and Mechernich- Voißel in the north, two towns that does not flow through the creek. Below and to the northeast of Voißel the riverine Mechernich- Glehn also bears the name of Schliemann Bach and Glehn to Mechernich- Eick says mill creek or Bruchbach.

Within the Rhineland the Rotbach flows in mostly north- northeast through the Jülich- Zuelpicher flange and passes through areas of Zuelpich after Lechenich to finally close Erftstadt- Dirmerzheim to open in the coming from the south, Rhine tributary Erft.

As orographic right-hand tributary of the lead stream flows at the Mülheim- Wichterich in the Rotbach.

Characteristics

Characteristic of the Rotbach is especially after heavy rains red - brown color of the water by the high iron content, which is also clearly visible in the fields on the right and left of the river. A high iron content through oxidation of the iron too bright to dark red / brown colors of the iron oxide.

Floods and Flood Protection

The Bach influenced life in Friesenheim significantly, possessors of lands and houses are located on its banks, which were flooded repeatedly since the 1960s when it rains. However, this danger is at the present time no longer as serious by the flood retention basins Erftstadt low mountain.
