 The Weißache in Kufstein |
||
The Weißache is an approximately 24 km long right tributary of the Inn in the Tyrolean lowlands . It flows through the Sölllandl , a valley between the Kaiser Mountains and the Hohe Salve .
Run and landscape
The Weißache rises at about 1500 m above sea level. A. on the Zinsberggrund in the Weißachergraben.
The Ache flows through the following communities downstream:
The first three belong to the Sölllandl, the latter two are in the Inn valley.
Between the Schwoich district of Egerbach and the Kufstein district of Endach, the rest of the Weißache flows through an approx. 800 m long gorge through an upstream ridge on the Kaiser Mountains, between Winterkopf ( 1226 m ) and Wöhrer Köpfl ( 782 m , Kufsteiner Forest ).
Then it enters the Kufstein basin and flows northwest towards the Inn . There it separates the districts of Endach and Weissach , which derive their names from the Ache, and flows into the Inn at Kufstein / Endach .
Catchment area and water supply
The Weißache drains a catchment area of around 120 km², the highest point of which is the Treffauer at 2304 m above sea level. A. is.
The mean discharge at the Kaiserwerk gauge, 5.5 km above the mouth, is 2.50 m³ / s, which corresponds to a discharge rate of 27.3 l / s · km². The Weißache shows a summer-strong nivo-pluvial runoff regime . The mean runoff in the month of April with the most water, at 4.49 m³ / s, is around three times higher than in the poorest month of January with 1.45 m³ / s.
Hydraulic engineering
Before the Eiberg Straße junction to Schwoich, the stream is divided and a large part is pumped under the Kufsteiner Wald mountain into a district heating plant in the south of Kufstein, where it serves as cooling water before it then flows into the Inn. This is where the second part of the Ache flows around two kilometers after the district heating plant.
In 2005, numerous bank protection measures were initiated in Kufstein. The creek has dug deeper and deeper in recent years, which is why the bank could slide off.
Water quality
The entire course of the Weißache has water quality classes I-II.
