 The Malscher Landgraben in the municipality of Ettlingen-Bruchhausen |
||
The Malscher Landgraben is a brook over 15 km long in the Upper Rhine Plain in western Baden-Württemberg , which flows into the northern Black Forest Alb from the right and south in Karlsruhe .
geography
course
The Malscher Landgraben begins its course on the southern edge of the Malscher part of the settlement in the lowlands. It arises at a little over 120 m above sea level. NN next to Jahnstrasse and initially runs open to the northeast through the settlement. Almost at its north-east end, it crosses under Sezanner Strasse, which has meanwhile been turned over, and is crossed next to it by the Lindenhardterwegbach , the right branch of the Malsch village stream. On the left is the Federbach , which follows the Adlerstraße at the junction of Neudorfstraße from the Adlerstraße - Sezanner Straße. If you count the Dorfbach and its upper reaches to the Malscher Landgraben, this would have been several kilometers longer.
When entering the corridor, it begins its long and very low-slope trench course through the wide Kinzig-Murg-Rinne immediately before the edge of the northern Black Forest in the east. From this several large right tributaries drain into it, partly with a cluster of tributaries from the Black Forest edge, which have formed notch valleys on their upper reaches, but in the flat land of the channel run like the ditch itself in artificial ditches. The first of these is the Krebsbächle , after whose mouth at the end of a wooded area the Landgraben turns away from the railway line, the dam of which it had followed from the end of the village from Malsch. Immediately afterwards, the above-mentioned Lindenhardterwegbach flows from the left of the A5 , then the Landgraben flows in a wide meadow between the Hardtwald on the left and the elongated forest island Buchtzig on the right, continuing northeast towards Ettlingen - Bruchhausen ; at the beginning and end of the Buchtzig there is a larger quarry pond .
In the Bruchhausen area, whose residential areas are on the left and hardly keep any distance from the course, the Reutgraben and Beierbach run towards the right. Here the Landgraben flows north, and immediately afterwards the Weiligbächle also drains from the right through an industrial zone that already belongs to Ettlingen itself. Here, only 1.5 km away from its receiving water Alb in the east, which leaves the Black Forest here, the Landgraben turns north-west and runs through the Hardtwald , initially accompanied by the Ettlinger line . He then leaves this at Hofgut Scheibenhardt again on the north-north-east run and then enters the built-up area of Karlsruhe between the districts of Oberreut left and Beiertheim-Bulach , where he follows the L 605 close to its clover leaf with the B 10 from the left and south-south-west the Alb running through the northern Black Forest flows into it.
From its origin on the southern edge of Malsch in the Upper Rhine Plain , the Malscher Landgraben runs as a collecting ditch with a length of 15.4 km with very little gradient in front of the Black Forest edge . If, on the other hand, you let it begin with the upper course Waldprechtsbach – Malscher Dorfbach, which drains into the Landgraben via its right branch Lindenhardterbach , but is usually included in its left branch of division Federbach , you would have to assume a length of at least 23 km, the source would then be almost 420 m above sea level NN . With the first right tributary of the Black Forest Krebsbächle as the upper course, which is about 453 m above sea level. NN west of Malsch- Volkersbach in the Black Forest rim heights, it would still have a length of 17.5 km.
Catchment area
The catchment area of the Malscher Landgraben covers 58.1 km² on the western edge of the Black Forest and in the Upper Rhine Plain. The brook itself runs as a collecting ditch that mainly flows from the right of the Black Forest and foothills in the Kinzig-Murg-Rinne a little in front of the distinctly pronounced mountain edge in the lowlands to the north-northeast, until then, from the mountain outlet, the Alb, which then initially runs parallel and later accommodates the land ditch suspend the inflows from this side. The catchment area is therefore composed of an approximate rectangle of 8.5 km × 6.5 km, aligned parallel to the edge of the Black Forest north-northeast and covering it, which extends from Malsch in the south-south-west to close to the Alb in Ettlingen, and one at its north-western corner in Muzzle wedge of 4 km × 1.5 km placed on the same alignment. About 38% of the catchment area is to the left of the course.
Adjacent catchment areas are that of the Alb in the north and east, that of the Federbach in the south and west, with which it shares an uppermost course and its tributary system ( Waldprechtsbach / Malscher Dorfbach , brook division in Malsch), which is, however, assigned to the Federbach.
The left watershed in the area of the Hardtwald is hardly noticeable in the terrain, the right on the flat mountain between it and the Black Forest course of the Alb is noticeably better. In the lowlands it is also strongly determined by human intervention, namely the orientation of the artificial drainage through ditches and urban sewers.

geology
The Malscher Landgraben is created in the Quaternary flood sediment of the Kinzig-Murg-Rinne , into which it also flows. In between, for example from the inlet of the Krebsbächle to behind Bruchhausen, a moor has formed along the course, and also partly along the Reutgraben, which flows into this area. The Landgraben is a very shallow step edge water that receives numerous tributaries from the right from the western edge of the northern Black Forest .
The stratified structure in the catchment area shows a very clear zoning parallel to the right edge of the Upper Rhine Graben, from the south-south-western watershed against the Federbach to around Ettlingen.
- In the east -south- east zone, on the edge of the Black Forest, there is mostly Upper Buntsandstein , on which a narrow strip of Quaternary loess sediment is superimposed in sections near the watershed ; In the valley cuts of the edge heights to the Rhine plain and at the edge of the slope to this, the rock belongs to the middle red sandstone .
- Loess sediment is found in the middle zone, with the exception of the above-mentioned water sediments close to the water, which run through it like a ribbon.
- In the west-north-west zone lies Würm gravel, on which the Hardtwald stands for a long time .
A suspected fault line of the Rheingrabenbruch runs between the middle and right zone along the edge of the Black Forest.
Landscape image
The geological zoning corresponds to one of the natural spaces. Where red sandstone is located, the Black Forest edge slabs (approx. 15 km²) extend , the right half of the loess sediment zone belongs to the Ortenau-Bühler foothills (approx. 11 km²), the larger rest of the catchment area is part of the Hardt Plains (approx. 33 km²).
