The Allna is a 19.1 km long, orographically right-hand and western tributary of the Lahn in the Marburg-Biedenkopf district .

The Allna mostly flows through the Gladenbacher Bergland in the north of the federal highway 255 in alternating eastern directions. Initially it runs through the north of the urban area of Gladenbach , then in the second half of the run through the municipality of Weimar (Lahn) and in between the Marburg urban area. At the Weimar district of Argenstein , it finally flows to the south-east.

The catchment area of ​​the Allna largely coincides with the more montane natural area Damshausen Kuppen in the west and the shallow and significantly narrower Elnhausen-Michelbacher depression , plus the western slope of the central and southern Marburg Ridge in the east. Since the Par-Allna has existed, which was artificially branched off shortly before Argenstein and followed the Lahn River a good bit to the right, it has also drained smaller parts of the Salzbödetal natural area .

geography

course

The Allna arises in the urban area of Gladenbach , northwest of Runzhausen, from a source that, like the uppermost tributaries, rises on the easternmost slopes of the so-called Allberge , like the 552  m above sea level. NHN high Daubhaus and its northern foothills in the southeast of the Bottenhorn plateaus are also called.

The Allna in Bellnhausen

On its upper reaches, the Allna flows first in an east- south- east direction via Bellnhausen to Sinkershausen , then in a south-east direction through Frohnhausen and Friebertshausen (all to the city of Gladenbach). Where the Ruchenbach, which comes from the district of the same name , flows into it, it runs east for a while to Allna (municipality of Weimar ).

At Allna, the river that gives the village its name turns left in front of the Anzekopf to the north-east, where it reaches the city of Marburg with the village of Hermershausen . There it flows towards the Ohe , approximately at its last bend to the south-east, its longest tributary, which had previously followed it parallel to the north-east, and which took in the Elnhauser water from the left immediately before its mouth .

After it has passed Haddamshausen and has been reinforced by the Cyriaxweimarer Bach coming from the northeast via Cyriaxweimar , the Allna near Niederweimar reaches the community of Weimar again and naturally the Marburg Lahntalsenke , where it remains up to its mouth.

Immediately north of Argenstein , the 4.5 km long right estuary Par-Allna has been branching off in a south-south-westerly direction since the summer of 2011 and thus follows the Lahn to the right parallel to the Lahn, while the main arm maintains its south-east direction and after half a kilometer from the right into the Lahn flows out.

The 19.1 km long course of the Allna ends about 178 meters below its source, it has an average bed gradient of about 9.3 ‰.

Natural allocation

The Allna and its tributaries drain the natural area and ridge Damshäuser Kuppen (320.10) in the upper and middle reaches of the longer rivers and in the lower reaches the Elnhausen-Michelbacher Senke (320.11), whose dividing line to the southern Salzbödetal (320.12) is essentially at the watershed between the Allna and the southern Lahn tributaries Salzböde (in the west) and Wenkbach .

The upper reaches of the Allna mainly drains the southern, the Ohe the central and northern Damshausen peaks, whereby the water from the north-eastern peaks, especially via the Waltersbach , first flows into the Elnhauser water .

The Elnhauser Wasser is the central flowing water of the Elnhausen-Michelbacher Senke, which extends to the south over the lower reaches of the Allna to the headwaters of the Rüchenbach and to the north it also contains the river area of ​​the Michelbach , which drains directly to the Lahn . The Elnhauser Wasser and the Allna from its mouth also absorb water from the western slopes of the central and southern Marburg Ridge (348.00).

The western dividing line of the peaks to the high plateau of the Bottenhorn plateau (320.01), to which the summit of the Daubhaus is already included, is again based on the watershed between Allna and Salzböde.

The discrepancy in the river indicators is due to the fact that the responsible state office stationed the Allna over the Strichbach coming from Runzhausen (20.3 km long). Its right, 1.5 km long tributary Tränkebach thus has the index of a direct tributary (25832-112). (Not listed in the table above, as the tributary is 2nd degree.) The Allna headwaters are not stationed at all, only that of the Langenbach, which will soon flow in from the right. The Allna is 19.0 km long over its named source arm, 1.7 km of it to the mouth of the Strichbach.

On the main flow issue

• When inflow of Ohe these almost 30% brings more water than the Allna itself (337.4 l / s vs. 263.1 l / s).
  • The Elnhauser water, in turn, brings slightly more water with it when flowing into the river than the river itself (170.5 l / s vs. 165.7 l / s)
    • After all, the Waltersbach brings more water with it when it flows into the Elnhauser Wasser than this (63.7 l / s vs. 58.4 l / s)

This would mean - strictly from a hydrological point of view - the hierarchy would be exactly the opposite, i.e. H. the Waltersbach would be the main river and Elnhauser Wasser, Ohe and Allna flowed to it one after the other!

Meanwhile, the Ohe doubles its amount of water per inflow of the Elnhauser Wasser just over half a kilometer before its confluence with the Allna. So z. If, for example, there is a reservoir around Hermershausen, the Allna would be the largest of its three tributaries.
