The Aimersbach is a right and northern tributary of the Rems in Lorch in the Ostalbkreis in Baden-Württemberg. It is 5.2 km long and has a water catchment area of ​​around 5.0 km², mostly in the Welzheimer Forest .

Naming

As with the nearby Götzenbach , the name of the Aimersbach also refers to a small Amor temple that belonged to Lorch Fort in Roman times . The stream is said to be named after this.

geography

course

The Aimersbach arises on the western edge of the hamlet of Brech, which belongs to the Pfahlbronn district of Alfdorf in the Rems-Murr district in eastern Baden-Württemberg and which has since grown together with Pfahlbronn. The unevenly narrow, west-east running plateau band, on which both main towns stand, is notched by the steep valley of the brook that begins on a swampy meadow on the edge of the forest next to the Beunden road. From there it flows with an even gradient towards the south.

The first two kilometers of its course, the stream flows in dense valley forest, then for a little less long in a narrow floodplain between wooded slopes, whereupon it enters the settlement area of ​​Lorch. At the valley exit, below the Haldenberg, the brook is twisted, crosses under the K 3334 and the railway line , flows past the cemetery and flows into the Rems as an extension of the street Am Friedhof behind a commercial building from the right and north, less than a hundred meters to the Rems the mouth of the Steindobelbach from opposite.

The Upper Germanic-Raetian Limes runs roughly on the left watershed to the Götzenbach . Its route shows landmarks. Sights in this area include several rebuilt foundations of watchtowers and the Bemberlesstein , on which grooves in the reed sandstone have been preserved. Partly on the Limes there is a forest sports path that starts and ends at the YMCA home and touches several tributaries of the Aimersbach in its course. On the western ridge in front of the neighboring valleys of the Haselbachbach and further down the Walkersbach , the Klotzenhof stands in a clearing island on the watershed, in the valley floor of the lower valley the facilities of the rifle club and the riding stables that Lise Gast founded.

Catchment area

The approximately 5 km² catchment area of ​​the Aimersbach extends as an elongated spindle from Pfahlbronn about 5 km south to the mouth. Across from it, it is nowhere even 1.5 km wide. In the west it borders along its entire length on the catchment area of ​​the Walkersbach , in the east on that of the Götzenbach .

Geology and landscape

The Aimersbach rises in the transition area between the Lower Jurassic plateau around Pfahlbronn and the Oberkeuper layers below . The brook itself then digs into the Keup layers. The mouth in the broad Quaternary sediment band around the Rems is probably just above the Gipskeuper ( Grabfeld formation ); This is because it only strikes a little downstream on the lower Rems valley slopes.

The Aimersbach runs in the natural area of ​​the Swabian Keuper-Lias-Land through the sub-units of the Vorderer Welzheimer Wald (No. 107.32) and finally the Upper Remstal (No. 107.11). The plateau on which Pfahlbronn stands belongs to the Welzheim-Alfdorfer Platten natural area (No. 107.31). Arising roughly at the border between the Lower Jurassic and Keuper, it runs through the Keuper for most of its flow path, in which many small blades converge. The valley of the Aimersbach is cut quite deep. Many small and tiny side streams and springs flow to it. The stream crosses the layers of reed sandstone and colorful marls.

history

Old traces of cultivation can still be found on many of the rivers in the Rems Valley. The forests of the Swabian Franconian Forest were mainly used for firewood. For this purpose, the streams were dammed in order to have enough water for rafting meter logs. At the Aimersbach there is still at 345.5  m above sea level. NN a small pond at the end of the upper course, where the boundary between Alfdorf and Lorch crosses and the Engelsklinge converges , and an old raftsman dam near the mouth of the Fuchsklinge , both of which were used to regulate water.

Fauna & flora

The valley is rich in plants and animals. There are several types of orchid ( two-leaf and orchid ). Sedges and rushes , as well as marsh marigolds and individual specimens of the globe flower grow in the ponds and man-made pools for amphibians . Common heather , blueberries and gorse thrive in the places where the reed sandstone is exposed . Up until the last decade, the forests were mainly characterized by spruce and fir trees; in recent years efforts have been made to turn the stands with colored deciduous trees .
