The Dölchengraben , also called Dölche , is a creek less than three kilometers long in the municipality of Haßmersheim in the Neckar-Odenwald district in Baden-Württemberg , which after mostly eastward runs near the village of Haßmersheim finally flows south and from the left into the Neckar .

geography

course

The Dölchengraben created about two kilometers west of the town center of Hassmersheim to a clump of trees in the hallway between the bathes Gießübel the west and reeds in the East etrwa 165  m above sea level. NHN . Through the meadow in the reed bed , it quickly turns on a long eastern run along dirt roads. Shortly before the allotment gardens on the western edge of Haßmersheim, the Baierfeldgraben flows from the left and west of the river, a creek of about the same length, which rises less than half a kilometer north of the Dölchengraben a little higher. .

The unified Dölche crosses the area, takes a right-hand bend, flows in this, accompanied by Dölchenstraße, past the cemetery and then along Schulstraße through built-up area and in sections to the south. Before they are a little west of the sports field around river km 90 at 138.6  m above sea level. NHN flows into the Neckar from the left, it still walks past the school and a playground.

Catchment area

The Dölche drains an area of ​​3.6 km². From a natural point of view, the catchment area belongs mainly to the Neckarelzer Tal sub-area of the Nauland , in which the two bodies of water also run; only the ridge heights in the west belong to the sub-area Neckarbischofsheimer heights of the Kraichgau . There is also the highest point in the catchment area on the summit of the Reichertsberg ( 294.6  m above sea level ). Beyond it borders the catchment area of ​​the Erlenbach , which flows into the Neckar in the downward district of Hochhausen . From northeast to southeast the watershed is not very pronounced and runs directly against the Neckar itself or insignificant tributaries from it. In the south, the scabbard runs in front of the Hohberg blade that also runs to it . A very short stretch in the south-west also borders the Mühlbach's catchment area .

A good half of the catchment area is plowed, mainly the loess-covered lowland areas in the corridor west of Haßmersheim, a good quarter are forest areas, especially on the mountain climbs in the west and south, of the rest around half is grassland or settlement area of ​​Haßmersheim.

Tributaries

  • Baierfeldgraben , from the left and west-northwest to 151.6  m above sea level. NHN shortly before the allotment gardens on the western edge of Haßmersheim, 1.3 km and about 0.9 km². Arises at about 1706  m above sea level. NHN in the Gewann Schelmenbaum about 0.4 km north of the source of the Dölchengraben, which is about as long to the confluence, but contributes more to the catchment area.

geology

The courses of Dölchengraben and Baierfeldgraben lie in the Quaternary level of loess sediment that covers the widening of the Neckar in Haßmersheim and to the west of it. To the west and south on the edge of the bay is the ascent to the Reichertsberg in the west and the Garnberg in the south - this reaches a similar height, but its ridge is already outside the catchment area - Upper Muschelkalk , which is quarried there in the Haßmersheim quarry. The Reichertsberg is covered by a cap from Unterkeuper , which also occurs on the southern border in islands against the Garnberg, partly overlaid with loess sediment.

Protected areas and biotopes

Less the Haßmersheim settlement area and the quarry area, the catchment area belongs to the Neckartal III landscape protection area. There is a reed zone below the spring. The lower half of the catchment area including all courses belongs to a water protection area in the catchment area of ​​the Haßmersheim deep well.
