The Welland is a hilly landscape in eastern Baden-Württemberg . In the natural division of Germany, it is the sub-unit No. 102.04 of the Swabian Keuper-Lias-Land in the south-west of Germany . It belongs to the natural area foreland of the eastern Swabian Alb (main unit 102).

description

The Welland is located in the Ostalbkreis in the Alb foreland. It borders in the north-west on the Liasplatten over Rems and Lein , in the east-northeast on the Goldshöfer Terrassenplatten , in the south-south-east on the Albuch in the neighboring natural area Albuch and Härtsfeld and in the south-west on a very short stretch of the Rehgebirge , which like the first two sub-areas mentioned is again in the eastern Alb foreland .

The lowest point on the edge of the Welland at 427  m above sea level. NHN Höhe lies at the re-outflow of the Rems at the Mögglingen hamlet of Hermannsfeld . Most of the total area is below 500  m above sea level. NHN , two of the few higher peaks in the center protrude a little more than 550  m , including the striking Kolbenberg near Aalen- Oberkolbenhof .

The population density is particularly high in the western districts of Aalen, which are now structurally directly connected to the city center, while central parts of the landscape apart from some overgrown villages are still relatively sparsely populated agricultural areas with scattered settlement farms and small hamlets. The open corridor clearly dominates, the rarer forest areas are small and scattered.

The border of the Welland touches the town of Heubach in the southwest , runs with an indentation around the crossed Rems above Mögglingen to the northeast up to the heights of the range of hills between Rems in the south and Lein in the northwest about southeast of the hamlet of Holzleuten von Heuchlingen , then northeast to the east further to the village of Dewangen von Aalen . There the borderline bends in front of the Kocher valley to the south-southeast, crosses the Aal tributary on the western edge of the city center of Aalen and, beyond its hollow, reaches the foot of the Langert am Albtrauf . It now runs along the foot of the Albtrauf to the west-south-west through Essingen , where the Rems flows in, all the way back to Heubach.

Surveys

The Welland is highest on its southern border at the Albfuß, where it includes the lower slope section, while the mountain heights are outside in the Albuch, and next to it on some iron sandstone knolls between the Aal upper reaches Rombach (with upper reaches) and Sauerbach or on the ridge between the upper one Sauernach and upper Sulzbach, which drains to the Rems.

  • Sandberg ⊙ 554  m above sea level NHN , north tip; the southern tip reaches about 553  m above sea level. NHN , in between on a little sunk saddle stands the Aalen hamlet of Sandberg
  • Kolbenberg ⊙ 552.8  m above sea level NHN ; The Essinger Oberkolbenhof is located on the eastern slope of the Höcker north-west of Essingen Forest
  • Schlossberg ⊙ 541.7  m above sea level NHN ; Essinger Hof Schnaitberg is located on the plateau of the mountain south-southeast of Forst
  • (Nameless summit) ⊙ 529.6  m above sea level NHN ; west-southwest of Forst, on top is the Essinger Weinschenkerhof
  • Schradenberg ⊙ 527.3  m above sea level NHN ; The Aalen Sofienhof is located at the southern foot of the Waldhöckers, west of the Aalen district of Hofherrnweiler
  • (Nameless summit in Spitalwald ) ⊙ 526.5  m above sea level. NHN ; The Aalen Pompelhof is located at the southeast foot of the forest knoll northwest of Hofherrnweiler.

Waters

The greater part of the Welland in the east and south-east drains via the itself only short Aal and its upper reaches Rombach and Sauerbach to the Kocher in Aalen. From its exit from the Alb, the more important Rems takes a left curve through the southwest and leaves the Welland westwards again before Mögglingen; Some mostly smaller bodies of water flow to it, too, which run at least partially in the Welland, the largest of them being the Lauter , which rises in the Alb and flows into Mögglingen , and the Klotzbach, which also comes from the Alb in Heubach and only touches the Welland briefly at its southwest corner . Since the natural boundary in the north-west and north is mostly drawn a little beyond the watershed to the Kocher tributary Lein and to the Kocher itself, the initial flows of some tributaries to these rivers are still in the Welland. The same applies to some of the tributaries of the Kochers in the east before its bend to the west near Hüttlingen . The following overview prays a selection without smaller bodies of water.

To the Lein in the northwest, downstream:

To the Kocher in the north and east, upstream:

To the eel in the southeast, upstream:

To the Rems in the southwest, downstream:

The valleys leading to the south and east are rather wide and flat, those to the northwest to the Lein are deeper and narrower.

geology

Layers of the Lower Jurassic and Central Jurassic are pending in the Welland . Except in the east to the Kocher valley and in the south-west near Heubach, where this layer continues on the other side, the natural area boundary roughly follows the outcrop boundary of the Opalinus Clay Formation , the lowest formation of the Central Jurassic. The high peaks of the south reach the iron sandstone above . Some valleys in the north have dug into the Upper Lower Jurassic, in extreme cases up to the Amaltheenton Formation . Under the Alb eaves, where narrow strips of higher Middle Jurassic strata also spread out, there is sometimes rubble. In places there are floating earths , occasionally also, due to the proximity of the valley judge of the Urbrenz near Aalen, small islands of Goldshöfer sands on hilltops. The large valley ranges are filled with alluvial sediment.

Administrative units

Most of the Welland lies in the area of ​​the city of Aalen , the municipality of Essingen in the south has a noticeably smaller share, and the city of Heubach on the southwestern tip has an even smaller share . At most Randzwickel in the west belong to the communities Mögglingen and Heuchlingen . The town of Aalen has expanded far to the west in closed development ( Hofherrnweiler , Unterrombach ), while its village of Dewangen , on the northern edge, has developed into a large commuter town.

limes

The Welland is traversed by the Upper Germanic-Raetian Limes , in the western part, where it can still be seen in places between Heuchlingen and Mögglingen, it runs roughly from west to east, then further north-east towards Hüttlingen.
