The Ilm (in typewriter : Ilm ) in Bavaria was originally a right tributary of the Danube and is now a left tributary of the Abens thanks to hydraulic engineering measures .
Surname
The Ilm got its name from the Indo-European word * el , which means "to move". In the year 821 one wrote Ilma , 890 Ilminam , 920 Ilmim and since 1322 Ilm .
course
Spring streams
The Ilm has three spring brooks by name in the Dachau district northeast of Altomünster . At Michelskirchen in the municipality of Hilgertshausen-Tandern , the smaller source stream Tanderner Ilm , which rises on the western edge of Tandern ( 48 ° 25 ′ 43 ″ N , 11 ° 17 ′ 40 ″ E at approx. 505 m above sea level ), meets the longer one and more than five times as large a quell stream Pipinsrieder Ilm . From its two own spring branches, indicated in the web map of the Bavarian surveying administration, the right one rises a little north of the district road DAH 2 from Altomünster to the district Pipinsried ( 48 ° 24 ′ 8 ″ N , 11 ° 16 ′ 27 ″ E at approx. 520 m above sea level. NN ). The source of the spring branch on the left, which is more than twice as large, is recorded as the origin of the Ilm in the first Bavarian image ( 48 ° 24 ′ 5 ″ N , 11 ° 15 ′ 55 ″ E ).
Middle course
In the further course the Ilm flows in a north-north-westerly direction through an elongated Muldental valley, which is sunk 50 to 80 meters into the Lower Bavarian hill country . The valley widens below Pfaffenhofen , the largest town in the Ilm Valley. Its cultural landscape in the Hallertau is shaped by the cultivation of hops.
Muzzle arms
A little above the Neumühle in Vohburg , a sluice divides the Ilm into three arms, the left and the middle arm flow together again and then merge with the Wellenbach to form the Little Danube ; This flows through the city, follows the Danube dike for about 5 kilometers and flows into the Danube from the right opposite Pförring . The right arm, on the other hand, initially pulls, tracing the wide arches of the old Danube loops, at a great distance from the river and only reaches the flood dam of the Danube below the described mouth, but opposite Pförring, which it then also follows to near Bad Gögging , where it turns from the left in the just abutting the dam, about the same size Abens flows. It follows the dam for a few kilometers to its mouth at Eining.
Until the mid-1920s, the Ilm was a tributary of the Danube and flowed into Gaden (municipality of Pförring ). As part of regulatory measures, however, the river was extended parallel to the Danube to the Abens. The old Ilm estuary is still preserved beyond the flood dam. Due to the flood drop above Vohburg, the Ilm hardly surpasses the Abens in terms of average water flow; Both rivers have an average of 3.2 m³ / s at the confluence.
