The Ilvesbach is an almost 7 km long brook in the urban area of Sinsheim in the Rhein-Neckar district in northeastern Baden-Württemberg , which, after a predominantly northeastern course in Sinsheim opposite the old city center, flows from the left and finally southeast into the middle Elsenz .

Surname

The Ilves Bach is in at least older local history literature and even on a map from the late 19th century Ilve r Sbach called. Also the name apparently has a female gender in the local dialect.

geography

course

The Ilvesbach begins its course at about 213 m above sea level. NHN about two kilometers west of the village of Weiler von Sinsheim and about 0.6 km southwest of the Hammerau residential area belonging to the district in the Great Forest at the beginning of the meadow bay in the so-called Hasenklinge which surrounds the northeastern course of the stream . Opposite a first widening of the corridor on the right-hand side are two small ponds close to the forest, after which he soon passes the Hammerau residential area on a hump above the right bank.

After that, on the Haferberg ridge that accompanies it on the left, which becomes flatter, the first field is close to the run. It flows past the Birkenauerhof on the right bank and then leaves the forest completely behind. A little later, from the west and the hamlet of Immelhäuser Hof, the Immelhäusergraben flows into; in terms of length and the added catchment area, a second upper course of the Ilvesbach.

Flowing in a not very deep hollow, it reaches the beginning of the nature reserve wetlands on the Ilvesbach on the middle course on the Gewann Oberer Alter See , recognizable in nature by the small square of a meadow fallow in arable land, in which for the first time larger trees are on the shore. There, from the slope of the Steinsberg ( 332.2 m above sea level ) in the south, a valley basin with a moat runs down from the Reut , from which the L 550 Weiler – Sinsheim crosses the stream.

In the middle of the nature reserve that accompanies the creek, which is around two kilometers long, the creek runs through the tree-lined flood retention basin Rauhwiesensee , in which a 2.3-hectare lake is permanently dammed . The built-up area of Sinsheim begins on the flat hills on the left, since the Rhein-Neckar-Arena surrounded by many parking lots was completed there in 2009 , while the right slope, which extends far up to the summit of the Steinsberg, is still an agricultural area.

The nature reserve ends shortly after the Asbach flows in from the south at Federal Motorway 6 , which the creek then crosses under . Beyond is a large industrial area of Sinsheim, through which the Ilvesbach turns to the northwest. It crosses under the Elsenz Valley Railway , which borders the industrial area towards the wide Elsenz floodplain, and passes the Sinsheim airfield on the right bank, which is followed by sports fields on this side and an outdoor swimming pool on the left. Finally, it flows past inner-city buildings to about 155 m above sea level. NHN opposite the city center between the Elsenzbrücke from Karlsplatz and that of Bahnhofstrasse from the left and southeast into the middle Elsenz .

The Ilvesbach flows after a 6.8 km long run with a mean bottom slope of only about 8.5 ‰ about 58 meters below its origin at the Great Forest.

Catchment area

The Ilvesbach has a 14.1 km² catchment area, all of which is naturally located in the Kraichgau . The stream rises on the edge of its lower area Eichelberg , then changes straight to the Eichelberg foothills and roughly at the tributary of the left upper reaches of the Immelhäusergraben in the Schwarzbachgäu . The highest point is 332.2 m above sea level. NHN high summit of the Steinsberg cone on the southern edge of the catchment area.

In an arc from Steinsberg in the south to Schindwasen in the northwest, in the upper area of the catchment area, there is the Great Forest , in which the upper Ilvesbach, Immelhäuserbach and lower Dührenergraben run in bays. The remaining, not built-up part of the catchment area is mostly under the plow, with the exception of only the damp central valley basin with meadows and the steep slopes on the upper and then again lower rocky mountainside, where orchards and bushy areas are located. Because of the Rhein-Neckar-Arena, which was completed in 2009 and its large parking spaces, to the left of the brook, the boundary of the urban development in Sinsheim begins at around the L 550 Weiler-Sinsheim, and on the right at the A 6.

The catchment areas of the following neighboring waters border in turn:

In the north-west the Erlenbach flows roughly parallel to the upper and middle reaches of the Ilvesbach, also to the Elsenz;
in the northeast, in the broad floodplain of the river, the Elsenz itself is the closest body of water;
in the southeast the small Ackerbach and on the steeper slope briefly the somewhat longer row stream drain the eastern slope of the Steinsberg to Elsenz;
from the southern foot of the Steinsberg the Sulzgraben or Sulzbachgraben runs a little further up to Elsenz;
behind the southern border from the Steinsberg to the southwest corner of the catchment area, the Hilsbach drains the other side to the uppermost, southeast-facing section of the Elsenz.
The watershed on the west-southwest side runs through the Great Forest, beyond it the Waldangelbach collects its uppermost tributaries, which drains over the Leimbach into the Upper Rhine. As part of the main watershed of the Kraichgau between the Neckar on this side and the Rhine above the tributary of the Neckar on the other side, this divide is therefore the most important hydrologically.

geology

Across the catchment area are underground Keuper -Gesteine on - except only the volcanic Härtling of Steinberg -Kegels on the southern edge, where in a Paleogene solidified volcanic vent of particularly erosion-resistant rocks or in its vicinity by metamorphosed contact were. Otherwise, the highest tertiary layer is formed by the lower colored marls ( Steigerwald Formation ), which are located in a tight ring around the higher Steinsberg, but especially in an arc around the upper reaches of the ridge in the Great Forest. In contrast, the upper upper reaches flow on reed sandstone ( Stuttgart formation ) for a long time , which in the area of the Ilvesbach itself extends as far as Hammerau. There, for example, the geologically deeper Gipskeuper ( Grabfeld Formation ) begins on the higher right slope of the valley , which stretches as far as the Rauwiesensee, but is also present in the northern catchment area in the higher elevations. Around the rest of the area, which is already more flat and hilly, up to the A 6, the older rocks are covered by loess sediments from the Quaternary . To the north-east of it, after a transition zone of flowing earth, the very flat and wide valley plain of the Elsenz, occupied by alluvial clay, begins.

The fact that the geologically deeper gypsum keuper is on the slope near Hammerau, while the geologically higher reed sandstone lies in the valley floor, is due to a fault line extending from the south-southwest to the north-northeast up to the inflow of the Immelhäusergraben, whose deep floe is on the right. A shorter fault line, also stepping upstream to the Ilvesbach, runs through the trough of the brook from the Reut to the northwest.

Rauhwiesensee retention basin

The middle course at about 167 m above sea level. NHN dammed up by a 3.9 meter high earth dam Rauhwiesensee was created in 1978 for flood protection and recreational purposes. It has a permanent damming area of 2.3 hectares and at normal times accumulates 25,000 m³, in the case of high water levels in the Ilvesbach up to 13,000 m³ more; the outflow is uncontrolled. The lake is surrounded by a partly wide belt of trees.

Nature and protected areas

The Ilvesbach is classified as a carbonate low mountain range rich in fine material. A few dry cracks in the blades run towards his three spring arms in or out of the forest. It flows in a straight line everywhere, accompanied by an initially quite thin and even discontinuous row of trees, which only becomes thicker at the middle course.

The 39 hectare wetlands nature reserve on the Ilvesbach runs along this middle course on both sides of the brook for almost two kilometers . From Steinberg down a large part of the nature reserve extends Steinberg almost to the right bank of the middle reaches. A small part of the large nature reserve Lower and Middle Elsenztal protrudes from the northern edge .
