geography

course

The Chräbsbach rises at 617  m above sea level. M. in the Bösmattmoos in Meikirch in the open corridor.

It initially flows through fields and meadows in an east-northeast direction, curves at the northern edge of a small forest and then runs east-south-east in the area of ​​the municipality of Wohlen near Bern, south of the village of Weissenstein. South of Schützenrain, the Chalchofebach flows into it from the left .

The Chräbsbach now moves southeast past Ortschwaben, then flows in an east-northeast direction through grassland and then passes the Niederlindach, which belongs to Kirchlindach . A little further down the stream, it is fed on its left by the Oberlindachbach .

It now runs along the south-east edge of Zollikofen , then turns sharply south and finally flows east of Reichenbach at an altitude of 486  m above sea level. M. from the right into the Aare.

Its 8.2 km long run ends about 131 meters below its source, so it has an average bed gradient of 16 ‰.

Catchment area

The 21.37 km² catchment area of ​​the Chräbsbach is located in the western central plateau and is drained via the Aare and the Rhine to the North Sea.

It consists of 22.2% wooded area , 68.5% agricultural area , 8.9% settlement area , 0.3% water area and 0.1% unproductive areas.

The mean height of the catchment area is 620  m above sea level. M. , the minimum height is 485  m above sea level. M. and the maximum height at 788  m above sea level. M.
