The Melach is a right tributary of the Inn in the Sellraintal in Tyrol with a length of approx. 23 km.
course
The Melach arises from the confluence of several headwaters north below the Lüsener Ferners in the municipality of St. Sigmund im Sellrain belonging Lüsenstal in the Stubai Alps . It initially flows north through the Lüsenstal. In Gries im Sellrain it unites with the Zirmbach coming from the western Sellraintal and turns to the northeast. It flows through the Sellraintal and takes in the Fotscher Bach in Sellrain . At the end of the valley near Kematen, it cut into a deep gorge before it emerges into the Inn valley, where it heaped up an alluvial cone and pushed the Inn northwards to the foot of the Martinswand . Between Unterperfuss and Kematen in Tyrol it flows into the Inn. This confluence represents the official dividing line between the Upper Inn Valley and the Lower Inn Valley .
Catchment area and water supply
The natural catchment area of the Melach is around 245 km², of which 5.1 km² (2%) are glaciated. The highest point in the catchment area is the Hintere Brunnenkogel at 3325 m above sea level. A. Several tributaries of the Melach are diverted into the Längental reservoir of the Sellrain-Silz power plant , reducing the effective catchment area by 60 km².
The mean discharge at the In der Au gauge is 4.08 m³ / s, which corresponds to a discharge rate of 28.3 l / s · km². The Melach has a runoff regime that is typical of a mountain stream without any significant glacial influence. The mean discharge in the month of June with the most water (8.06 m³ / s) is around five times higher than in the month of February with the least water (1.57 m³ / s). Heavy rains and heavy snowmelt regularly caused the Melach to overflow its banks, especially in the lower reaches. Bank protection structures to protect the fields and meadows around Kematen are mentioned as early as 1280. Most recently, in June 1965, the fields in the Inn Valley were flooded and the embankment of the Arlbergbahn was flooded , which was interrupted for two weeks.
environment
The source streams and the upper reaches of the Melach in the rear Lüsenstal are located in the quiet area of the Stubai Alps, where their course is largely natural, from the Juifenau above Gries the banks of the Melach are almost continuously built up. The Melach has water quality classes I-II throughout its course .
Surname
The name of the Melach, formerly also known as Melchbach, Melch or Malch, is derived from the word “milk”, alluding to the milky-white water ( glacier milk ). In contrast, the name is also associated with the root mel “gloomy” (related to the Greek μέλας).
