The Seebächle is a little over three kilometers long creek in the area of ​​the municipality of Obersulm in the district of Heilbronn in Baden-Württemberg , which flows from the right into the middle Sulm after a total of approximately southwest running in the middle of the village of Willsbach of the municipality .

geography

course

The Seebächle arises inconsistently about 2.6 km northeast of the center of Willsbach in the Obersulmer Waldgewann Sulz on a warped path star close to the border with the Bretzfeld Waldgewann Tiergarten at about 263  m above sea level. NHN . The stream that only carries water periodically on its upper course in the forest in the Brunnenklinge runs roughly west-southwest through the forest and then after about a kilometer, at the foot of the Greut / Dachsen vineyard slope on the right, over into the open corridor, in which the now permanent water A gallery of trees accompanies the body of water up to the settlement boundary of its estuary.

Immediately afterwards an equally unstable Waldklingenbach flows from the Fuchsklinge to the east , it runs through a reed field in the Greutwiesen and immediately experiences a short inflow from the Dachsen from a source in the area of ​​the reed, turns to about the southern course and now moves through a narrow meadow. At least three further tributaries follow from the right and left, all of which are at most one kilometer long and, like the branches mentioned above, also only carry water inconsistently. In the lake meadows in front of the spur of the Hirschberg , the Seebächle passes a 0.1 hectare pond on the left bank with a small forest island.

About 2.7 km down from its forest origin, the stream flows through at a little below 195  m above sea level. NHN the usually dry basin of the flood retention basin Seebächle, which can hold back up to 172,000 km² of water directly behind the embankment of the Heilbronn – Crailsheim railway line in heavy rain . The stream then flows through the right-wing Sulmic part of the Obersulm village of Willsbach in a south-westerly direction and finally flows at about 185  m above sea level. NHN a few meters down the valley from the bridge of the bridge road of the village in the middle Sulm , less than thirty meters after the inflow of the Hambach just before the bridge.

The Seebächle flows after a 3.2 km long run with an average bed gradient of about 24 ‰, calculated from its inconsistent forest source, about 78 meters below this source.

Catchment area

The Seebächle has a catchment area of ​​3.4 km², which , in terms of natural space , lies with its higher northern and especially northeastern parts in the sub-area Sulmer Bergebene , with the remaining part in the sub-area Weinsberger Tal of the Swabian-Franconian forest mountains . The highest point in the north-northeast on the Gagernberg reaches 313  m above sea level. NHN .

A half-ring open to the south-west from mostly 295– 313  m above sea level. NHN high reed sandstone plateaus ( Stuttgart Formation ) surrounds the upper and middle catchment area of ​​the Seebächle. Loess and loess sediments from Quaternary deposits lie on top of these . The parts below are all in the Gipskeuper ( Grabfeld formation ), which stretches in the uppermost catchment area and on the left side of the Seebächle almost down to Willsbachs and down to the edge of the floodplain. Opposite on the lee slopes it is already covered with loess-bearing floating earth and loess sediment at a great height and up to the edge of the floodplain. Holocene runoff masses lie in the floodplain .

Two marl pits in the catchment area are designated as geotopes, both are to the left of the Seebächles at about 240  m above sea level. NHN , one on the front spur between the fountain and fox blades, the other a little to the east above the lake at the middle course of the brook, both open up the middle gypsum horizon of the gypsum keuper and adjacent layers of the gypsum keuper.

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

  • In the north is the headwaters of the Sülzbach , the next right Sulm tributary;
  • the short upper reaches of the Waldbach , which drains via Dimbach , Schwabbach and Brettach to the Kocher , arise in the northeast , a tributary of the Neckar below the Sulm; This section of the entire watershed is therefore the most important hydrologically;
  • the outflow to the other side in the southeast reaches the Sulm via the Michelbach and a somewhat lower right-hand tributary from it, a little upstream of the Seebächles;
  • on the west side the deeper catchment area of ​​the already mentioned Sülzbach borders.

On the heights to the north and northeast of the catchment area, there is forest, which takes up a little less than half of the total area. The south-facing mountain slopes, which make up a large part of the open corridor, are mainly used for viticulture: to the right of the lower fountain blade in the Dachsert and Greut tubs at the southwest end of the Gagernberg ; in the Beerlesrain district on the southern slope of the Hirschberg ; in the Hohbergle and Brauchert areas further south. In the rest of the open corridor, the fields dominate, except in the meadow meadow near the stream.

The only settlement in the catchment area is the Obersulmer village of Willsbach . Almost the entire catchment area also belongs to Obersulm; The Wimmental submarket of Weinsberg in the north-northwest, the non-settled north-eastern community exclave of Ellhofen in the north-northeast and the Dimbacher and Waldbacher subdistricts of Bretzfeld in the north-east have narrow margins .

Tributaries and lakes

Origin of the Seebächles at about 263  m above sea level. NHN about 2.6 km northeast of the center of Obersulm- Willsbach on a warped forest road star close to this side of the municipality boundary from Obersulm to Bretzfeld . The stream flows inconsistently for the first kilometer of its course westnüps-west through the fountain blade

  • (Bach from the fox blade ), from the left and about east to about 220.5  m above sea level. NHN shortly after the forest emerges in the Greutwiesen , approx. 0.6 km and over 0.2 km².

This other, also unstable upper course of the stream from the Zeilrain arises at about 288  m above sea level. NHN a little north of the old quarry on the Zeilberg .
  • RiverIcon-SmallLake.svgFlows through to something below 185  m above sea level. NHN the usually dry basin of the Seebächle flood retention basin.

Mouth of the Seebächles from the right and northeast to approx. 185  m above sea level. NHN in Willsbach a few meters down the valley of the bridge of the Brückenstraße in the middle Sulm . The Seebächle is 3.2 km long and has a 3.4 km² catchment area.

Seebächle flood retention basin

The Seebächle flood retention basin ⊙ , which is only used for flood protection and not permanently dammed , is traversed by the water. It is located shortly before Willsbach behind the embankment of the Heilbronn – Crailsheim railway line and has a catchment area of ​​around 3.1 km². Up to 172,000 m³ of water can be retained behind the 13.3 m high earth dam, the discharge of which is controlled. The structure was built in 2006 and is operated by the Sulm water association.

Nature and protected areas

The fountain blade, in which the uppermost Seebächle flows, the fox blade that runs up to it and the other valley valleys that are still flowing are, at least in the upper part, steeply cut notch valleys typical of gypsum keupers, on the bottom of which water does not flow permanently.

The reed area in the Greutwiesen at the first change in direction of the stream and the somewhat larger peripheral areas around them are protected as a 1.6 hectare natural monument of the Greutwiesen wetland .

From the foot of the Hohbergles to the retention basin, the gently meandering, about half-meter-wide brook runs in a terrain notch that is almost two meters deep and about four meters wide. On both sides, a narrow strip of alluvial forest accompanies the water, above which the treetops close.

  3. ↑ The description of the northern geotope on the spur between Brunnenklinge and Fuchsklinge mentions the Middle Gypsum Horizon of the Gipskeuper as well as Lower Colorful Marl ( Steigerwald Formation ), which were only deposited over the sandstone reeds as a result of the Mesozoic layers; the description here is therefore probably incorrect. Because the description of the southern geotope on the road from the Hirschberg names, at approximately the same altitude, in addition to the middle gypsum horizon, the lower colored estherias , which belong to the gypsum keuper. According to both geological maps consulted, both outcrops are in any case entirely part of the gypsum keuper.
