The Asenbach is a right side run the lower Isar in the Lower Bavarian town of Dingolfing , by the districts Frauenbiburg flows and Dingolfing. The local group Dingolfing of the Bund Naturschutz is responsible for the brook sponsorship of the water.
administration
According to Art. 2 of the Bavarian Water Act, the Asenbach is a body of water III. Order . This means that the municipality, in this case the city of Dingolfing, is responsible for expanding and maintaining it. In 1992, the Federation of Nature Conservation -Ortsgruppe Dingolfing transferred the brook sponsorship, and in the following years created a water management plan, which could not be implemented due to the ownership structure.
geography
The Asenbach flows below the Teisbach to the Isar.
swell
Of the two source brooks of the Asenbach, which flow together above the Dingolfing hamlet of Oberbubach , the orographic left-hand (western) one with a length of 1820 meters is slightly longer than the right-hand one with 1790 meters and is included in the register of creek and river areas in Bavaria, river area Isar referred to as the source of the Asenbach. This left source stream is also known as the Holzhauser Graben (more rarely the Holzhausener Graben ). This name is derived from the hamlets of Oberholzhausen, below which its source lies, and Unterholzhausen, which lies to the left (north) of its course. The right source stream is also known as the Aubach . The same direction of flow speaks in favor of designating the right source stream as the origin of the Asenbach, as is the case with the Dingolfing Nature Conservation Group. In addition, there is the larger catchment area of the right Quellbach (around 300 compared to 200 hectares ), as well as the fact that the name Asenbach is entered here on the official topographical map on a smaller scale .
Oberbubach is also currently referred to as the origin of the Asenbach, namely in another document from the Bavarian State Office for the Environment.
course
The valley of the Asenbach is largely asymmetrical, similar to the Teisbachtal, which runs parallel up the Isar, with wooded steep slopes on the right in the east and agricultural flat slopes on the left in the west, on which there are some hamlets and villages , including Oberholzhausen, Unterholzhausen, Mietzing, Oed, Frauenbiburg and Schermau. The hamlets Oberbubach (for almost 100 meters) and Unterbubach (where the only tributary Schermauer Graben flows through ), the Spiegelbrunn settlement and the Waldesruh district are immediately traversed before the water in front of the Herrenweiher district (am Gries) bends to the northwest The mountain spur of the Upper City cuts through from the high bank of the Isar Valley. There the water was laid underground because of the narrow course of the dam path between the high banks under the sidewalk. At this point, the Asenbach is crossed by the distinctive high bridge built in 1612 with its five round arches up to 18.4 meters high. In the Middle Ages there was a wooden bridge here.
The Herrenweiher and further the eastern moat of Dingolfing was fed by a diversion in front of the high bridge and served as a reservoir for the Lochmühle (today Griesgasse 28), from which the watercourse along the Griesgasse and the Wollerzeilen (today's Marienplatz) ran towards the Isar . The Herrenweiher was filled in around 1880, and a gymnastics garden for the upper town boys' school (today an industrial museum) was created. Today there is a children's playground on the site of the former Herrenweiher.
A nearly 100-meter-long section of the Asenbach in Oberbubach runs underground, as does a 75-meter-long crossing under the earth dam of the Asenbach flood retention basin above the Spiegelbrunn settlement .
muzzle
Due to the construction of the flood dam along the Isar, the estuary was relocated to a point around 60 meters above the Isar bridge in the 1950s. For this purpose, an inlet structure was built in the dam, which enables the diversion into the drainage ditch (receiving water) in the event of flooding. The mouth lies at the height of the river kilometer 45.62.
Catchment area and length
The Asenbach has a catchment area of almost 16 km², which is mostly in the urban area of Dingolfing (districts Frauenbiburg and Dingolfing) and a small part in the southeast in the municipality of Marklkofen (district Frauenbiburg). Together with the source stream Holzhauser Graben , it has a length of 7.06 km, or 5.24 km from the confluence of the two source streams.
Only in the area of the right Quellbach does the catchment area of the Asenbach extend beyond the city limits of Dingolfing into the neighboring municipality of Marklkofen, namely around the Wildenschönau homestead. At 493 meters, the Schönauer Berg near Wildenschönau is the highest point in the catchment area. The point also marks the borders to the catchment areas Gottfriedinger Bach and Vils (Aiglkofener Bach and Reitbauernbach).
history
Old name Bubach
On sheet 64 (Landau) of the Topographical Atlas of the Kingdom of Baiern this side of the Rhine from 1835, the Asenbach is recorded under its previous name as Bubach (only below the confluence of the two source brooks), not to be confused with the Bubach flowing into the Isar below Mamming . In the corresponding repertory of the atlas sheet, next to Bubach, today's name variant is in brackets. After that it has its origin in Ober-Bubach , for which it was named as well as for Unterbubach . The above source streams are not mentioned there and are also unlabeled on the atlas sheet. On the original position sheet from 1866 it appears in the separate notation Bu-Bach .
