The Gadmerwasser is a 17.6 kilometer long right tributary of the Aare in the Swiss canton of Bern . It drains the Gadmertal and its side valleys in the Bernese Oberland , an area of ​​168.85 square kilometers.

geography

course

The Gadmerwasser rises on the northern slope of the Giglistock ( 2900  m above sea level ) and flows mainly in a south-westerly direction through the wooded Gadmertal.

The river takes early major tributaries, including the Gigli Bach , the 5.8 km long on Steingletscher springing stone water and at the turn of glaciers springing turning water . It now passes the village of Gadmen , flows through the Fuhren equalization basin and takes in the Trift water from the left at Milistalden and a little later the main inflow Gentalwasser from the Gental .

3.6 kilometers later the Gadmerwasser flows into the Aare from the right at Innertkirchen .

The approximately 17.6 kilometer long course of the Gadmerwasser ends approximately 1621 meters below its source, so it has an average bed gradient of about 9.2%.

Catchment area

The 168.85 km² catchment area of ​​the Gadmerwasser lies in the Urner Alps and is drained through it via the Aare and the Rhine to the North Sea.

It consists of 19.0% planted area , 16.4% agricultural area , 0.7% settlement area and 63.9% unproductive areas.

The area distribution

The mean height is 2097  m above sea level. M. , the minimum height is 621  m above sea level. M. and the maximum height at 3473  m above sea level. M. .

Main hydrological strand

Direct comparison at the confluence:

Surname Length in km Catchment area in km² mean discharge in m³ / s
Gadmerwasser 3.1 5.7 0.45
Stone water 6.8 24.3 1.98

The Steinwasser is longer than the Gadmerwasser at the confluence, it has a larger catchment area and a larger mean discharge (MQ). It is thus the main hydrological strand .
