West Hesse Highlands

The West Hesse Highlands (German: Westhessisches Bergland), also known as the West Hessian Lowlands and Highlands (Westhessisches Berg- und Senkenland), refers to a heavily forested region of the Central Uplands in Germany that lies mostly within the state of Hesse, between those elements of the Rhine Massif right of the Rhine in the west, the Weser Uplands to the north, the East Hesse Highlands to the east and the Wetterau to the south.

The West Hesse Highlands are one of the major natural regions of Germany (no. 34 or D46) and are part of the Central European Uplands as well as being the watershed between the Rhine and the Weser.

The West and East Hesse Highlands or Hesse Highlands correspond to the geological unit known as the Hesse Depression[1] (Hessischen Senke), in its wider sense, because here geologically young layers of Zechstein and Bunter sandstone, and in places even younger rocks like Muschelkalk, of the Jurassic, Paleogene and Neogene periods, have been preserved.[2]

Division of natural regions

The following geographical units (3-digit numbers) are taken from the Hesse Environmental Atlas (Umweltatlas Hessen):[3]

Landscape characteristics

The tectonics of the Upper Rhine Rift, which continue along the eastern edge of the Rhenish Massif as far as the Upper Weser Hills, form highlands and lowlands here that merge into the volcanic East Hesse Highlands beyond the West Hesse Depression on their eastern perimeter. The ridges never attain the height of the loftiest peaks of the highlands to the east and west.

Although the two highland areas of this Central Uplands region reach heights of 675 m (Kellerwald) and 615 m (Habichtswald), the typical height of the ridges is more like 400 m. Between them, there are large river valleys and depressions, in places up to 200 m lower.

Location of the geographical units

The Habichtswald highlands, which are up to 615 m high, in the north are separated from the peaks of the Waldeck Plateau (Waldeck Plateau) to the west, generally between 400 und 500 m high, by the East Waldeck Basin (East Waldeck Basin). Immediately south of the plateau is the 675 m high Kellerwald. The latter runs away to the south, splitting into two ridges mainly around 400 m high: the Burgwald, to the southwest, and the Upper Hessian Ridge to the south.

South of the Burgwald is the Marburg-Gießen Lahn Valley to the west (up to 380 m high near the Lahnberge) and the Amöneburg Basin to the east, which is flat apart from the singularity of the 365 m high Amöneburg itself. The basin rises southwards into the 405 m high (Lumda Plateau) Vogelsberg foothills. In the far east, the West Hesse Depression runs alongside almost all the ridges mentioned, following the valleys of the Schwalm (south) and Eder (north).

The northern part of the Burgwald, the southwestern Kellerwald and the Upper Hessian Ridge form part of the Rhine-Weser watershed and link the Rothaargebirge with the Vogelsberg.

The many depressions in the West Hesse Highlands and Lowlands have led to a build up of loess soils, which is why arable farming is widespread here.

Rivers

The main rivers in the West Hesse Highlands flow from the west out of the Rothaargebirge: the Diemel (only right-hand tributaries, north), Eder (middle) and Lahn (only left-hand tributaries and river valley, south). Whilst the two rivers of the Weser river system in the extreme northeast (Diemel) and east (Eder) discharge into the West Hesse Depression, the Lahn leaves the Highlands after following a semi-circular course and heads southwest into the Rhine Massif again.

The right-hand tributaries of the Wetter, a tributary of the Nidda and thus part of the Main river system, only enter a small part of the Vogelsberg foothills in the extreme southeast. In addition, a few left tributaries of the Fulda from the Habichtswald highlands join the Fulda itself just below the Eder confluence.

Table of the most important rivers

The following table lists the most important rivers in the West Hesse Highlands, from north to south and internally in a downstream direction, i.e. mainly from west to east.[4]

For a better overview or to sort them downstream based on the river system, enter the following DGKZ code numbers after the number 44 - Diemel, 428 - Eder, 24 - Fulda, 258 - Lahn and 2484 - Wetter.
Natural regions in italics are those outside the West Hesse Highlands; catchment areas and discharge quantities are given in italics where they only represent part of the total value (see footnotes below the table)!

Schwalm and Ohm

The two longest and biggest rivers in the table by far, the Schwalm und Ohm have a special role. They both emerge in the Vogelsberg, which the Ohm leaves after about 45% of its total length and 27% of its catchment area with roughly 35% of its volume[4] (see also here). The Schwalm, on the other hand, leaves the Vogelsberg much earlier and receives about half its water volume at its mouth from right-hand tributaries from the East Hesse Highlands.

Because the river systems of both rivers drain several major areas, they may be considered more or less as major rivers.

Rivers which enter the Schwalm from the left out of the West Hesse Highlands include the following:

Significant tributaries from the middle and lower courses of the Ohm are:

Other rivers crossing the boundary of this natural region are the Twiste in the northwest, the Kleebach in the southwest and the Wetschaft in the west.

The Wetschaft, which is fed from the left by the Burgwald, receives more water at its confluence with the Treisbach (r, 16,8 km, 68,2 km²) flowing out of the Rothaargebirge (810 l/s) than it delivers to that point (666,2 l/s), despite the fact that it has already been fed from the right by the East Sauerland Hills

The Kleebach on the other hand draws most of its water from the Eastern Hintertaunus, only receiving a small quantity of water from the Vogelsberg foothills via its right-hand stream, the Lückenbach (12,0 km, 38,9 km², 139,7 km) .

Opposite, the Twiste rises almost in the East Sauerland Hills, but receives, apart from this source region, all its water from the West Hesse Highlands. Likewise, only a little water flows into the Itter in the northwest from the eastern slopes of those particular hills.
