The Fildrich (formerly Filderich ) is a 16.1 kilometer long left tributary of the Chirel in the municipality of Diemtigen in the Swiss canton of Bern . It flows through the Diemtigtal , a side valley of the Simmental in the Bernese Oberland , and drains an area of ​​86.7 square kilometers.

geography

course

The Fildrich arises at 1910  m above sea level. M. through the confluence of two source streams at the Männliflue ( 2652  m above sea level ) in the Diemtigtal Regional Nature Park and mainly flows through the park in a north-easterly direction. It passes the villages of Grimmialp, Schwenden and Zwischenflüh, takes in the tributaries Senggibach, Gurbsbach and Narrenbach, and flows into the shorter Chirel from the left at Horboden.

Catchment area

The catchment area of ​​the Fildrich measures 86.77 km², of which 45.8% is agricultural area, 31.8% wooded area , 21% unproductive area , 1.2% settlement area and 0.2% water area.

The highest point of the catchment area is 2647  m above sea level. M. on the Männliflue , the average altitude is 1656  m above sea level. M. and the mean annual precipitation is 1760.005 mm on the upper course, 1707.467 mm on the middle course and 1680.162 mm on the lower course.

In addition to the neighboring community of Diemtigen, the communities of Boltigen , Därstetten , Erlenbach im Simmental , Oberwil im Simmental and Zweisimmen also have a share in the catchment area . Tiny areas are located in the communities of Adelboden , Frutigen and St. Stephan .

EZG

[in km²]

MQ

[in m³ / s]

Chirel 08.0 28.61 0.88
Fildrich 17.4 86.77 2.54

The longer Fildrich also has the larger intake system and is richer in water. It is thus the main hydrological branch of the Chirel river system . The total length of the Chirel-Fildrich line is 21.3 km.

Discharge values

At the confluence of the Fildrich in the Chirel, its modeled mean flow rate (MQ) is 0.88 m³ / s. Its discharge regime type is nival alpine and its discharge variability is 18.
