The Chise , also called Kiese or Chisebach , is a 21 km long right tributary of the Aare in the Swiss canton of Bern .


The water body name Chise has the meaning of the gravelly , the gravel bearing .


Spring streams

Several spring streams form the Chise south of Rünkhofen

Berggräbli - Chise

The Berggräbli is the middle source stream. It is referred to by some as Chise from the inflow of a small nameless side ditch (with the cantonal water number 56827).

The stream rises south of Buch at an altitude of 772.8  m above sea level. M. in a forest strip.

It flows southwards to the northern edge of Oberhofen, where it is fed on its left by the Gurnitalgrabe . He now turns to the west and shortly afterwards takes the small ditch, from which some people already refer to him as Chise.

The stream now flows around Oberhofen extensively from the west and joins the Dürrbach and Schwändibach to the south of the hamlet of Rünkhofen , which belongs to the municipality of Bowil, and to the east of the Groggenmoss group.


The Dürrbach is a left source brook of the Chise.

It rises with numerous source streams on the northern slope of the Kurzenberg at around 1100 m above sea level. At first it flows north and reaches the valley furrow at the village of Bowil, which ensures an easy connection from the Aare valley to the Emmental. At Rünkhofen it flows together with the middle Quellbach and Schwändibach.


The Schwändibach is a right source brook of the Chise.

It has its origin on the southern slope of the bladder river and flows south through the Kerbtal of the Schwändigraben . At Rünkhofen it steps out into the valley furrow and unites with the middle source stream and the Dürrbach.


After the union of its source brooks, the Chise now flows with a very slight gradient westward through this valley depression, the valley floor of which is sometimes more than 1 km wide.

At Konolfingen it turns to the south, whereby the Kiesental narrows over a distance of 3 km and is flanked by the heights of Häutligen in the west and by the Kurzenberg in the east. At the exit of Oberdiessbach , the Kiesental widens again. The river curves here to the west and flows in a wide valley that is filled with erosion material from the upper catchment area.

So the Chise reaches the Aareniederung and flows out at 535  m above sea level. M. west of the municipality of Kiesen from the right into the Aare.

The Chise is characterized by a nivopluvial runoff regime .

Catchment area

The 71.18 km² catchment area of ​​the Chise is drained via the Aare and the Rhine to the North Sea and belongs to the catchment area of ​​the Rhine. It drains a section of the hill country between the Aare valley and the Emmental .

The catchment area consists of 34.1% wooded area , 56.4% agricultural area , 9.3% settlement area and 0.2% water area.

Area distribution

The mean height of the catchment area is 1636  m above sea level. M. , the minimum height is 667  m above sea level. M. and the maximum height at 2647  m above sea level. M.


Among the noteworthy side streams are the zezibach , which flows into zziwil , and the diessbach , which reaches the chise at Oberdiessbach.

Discharge values

At the confluence of the Chise into the Aare, its modeled mean flow rate (MQ) is 2.1 m³ / s. Her discharge regime type is pluvial supérieur and her discharge variability is 24.

The modeled monthly mean discharge (MQ) of the Chise in m³ / s


Floods in the Chise repeatedly caused damage, especially in the lower area in the municipalities of Herbligen , Oppligen and Kiesen, where the river overflowed in the 1970s and August 2005. In the event of high water, it is calculated that the Chise can have a discharge of 28 m³ / s in the lower reaches . Flood protection measures have been planned since 2003 . They include the construction of retention basins in Groggenmoos near Bowil and in Hünigenmoos near Konolfingen, as well as widening and lowering the stream bed in the lower reaches. The retention basin in Groggenmoos was built in 2013, and there is resistance from the population to the rest of the projects - on the one hand because of the loss of cultivated land associated with the planned renaturation measures, on the other hand because of encroachments on private properties in the built-up areas of the lower reaches. Flood protection is coordinated by the Chiesbach Hydraulic Engineering Association, to which the communities along the Chise belong.

nature and environment

In the agricultural areas between Konolfingen and Bowil, the water has been straightened and canalized. Sections of the lower reaches of the Chise are still in their natural or near-natural state.


The hydropower of the Chise was previously used, especially in the Oberdiessbach area, to operate mills, sawmills and forges.
