geography

course

The Nonnenbach arises from the confluence of the Sandbach, Quebbebach (right) and Ahrensbach (left). The confluence is located near the Epe-Malgarten district of Bramsch, in the immediate vicinity of the Nowotny memorial stone . In the north of the river, the Pelkenbach joins the municipality on the right and passes the Lower Saxony Park . At the bridge on Neuenkirchener Straße in Rieste, the Vördener Aue is recorded from the right and the Aalgraben from the left . A few hundred meters before the confluence with the Hase begins the area of ​​the municipality of Alfhausen, here the Westendorfer Abzug flows into the Nonnenbach from the right . In the Alfhausen district of Heeke , the Nonnenbach flows into the Hase.

history

In the summer of 2010, an alluvial forest in the area of ​​the Malgarten district of Bramsch was connected to the stream again. The oxbow lake was separated from the flowing stream for about 160 years. For this purpose, a base ramp was created in the creek from 170 tons of Ueffeln quartzite, which floods the oxbow lake with water at mean water.

In 2017, the Pelkenbach , which flows into the Nonnenbach , was found to be contaminated with polycyclic aromatic hydrocarbons (PAH). The concentrations found in the sediments of the stream were between 0.12 and 77.60 mg / kg of dry matter.
