River system of the Weser

Structure of the catchment area, waterway indicators in red

The two source rivers Werra and Fulda are well known in the Weser river system . Another characteristic is the weight of their largest tributary, the Aller .

Catchment area

In the area of ​​the more water-rich but shorter source river Fulda, its largest tributary, the Eder, is more water-rich and slightly longer than the Fulda above the mouth of the Eder .

The catchment area of ​​the Aller is larger than that of the Werra and Fulda combined and larger than the sum of the area of ​​one of these source rivers and sub-catchment area of ​​the Weser from the confluence in Hann. Münden to the Aller confluence. With the Leine, the Aller area contains the longest river in the Weser system after the Weser and Werra, and the longest flow path to the Weser from the source of the Oker to the mouth of the Alles . The catchment area and outflow of the Leine are larger than those of the Werra.

The largest sub-catchment areas:

- sorted by size, but most areas come in several amounts -

• Weser above the Allermouth with Werra and Fulda, 22,203.34 km²
• All in total, 15,721.01 km²
• Werra and Fulda together, 12 443.59
• Weser from Hann. Münden to the Allermouth, 9,759.75 km²
• Weser below the Allermouth, 8 353 km²
• All above the estuary of the Lein, 7 442.71 km²
• Fulda as a whole, 6,946.59 km²
• Leine, 6,517.35 km²
• Werra, 5 497 km²
• Eder total, 3 361
• Fulda above the mouth of the Eder, 2,996 km²
• Hunte, 2,785 km²
• Lesum, 2,188 km²
• Eder above the mouth of the Schwalm, 1,827 km²
• Oker, 1,822 km²
• Diemel, 1,762 km²
• All above the mouth of the Oker, 1,708 km²

Flat land:

In the lowlands and marshland on the Weser and its tributaries north of the Porta Westfalica , complicated water networks were created for drainage but also for irrigation. Here, but also above the exit of the Else von der Hase , some areas cannot be clearly assigned to one or the other (sub) catchment area.

Water network

Rivers in the Weser river system are blue, outside blue-gray

The Weser, its source rivers and most important tributaries and their most important tributaries from 25 km in length or 100 km² catchment area
Representation: Upstream order A body of water flows into that of the river courses listed above, the name of which begins above the indication of the confluence side ("right" / "left") of the flowing water. Arrows are directed downstream and are in front of geographically upper parts of a previously mentioned river course. Watercourses that start as a branch from a larger body of water are entered twice (provided they do not leave the river basin): at the water from which they branch off, highlighted in blue at the water into which they flow, highlighted blue-gray Lengths given after the slash refer to the course of the river according to the official classification in contrast to the traditional use of the name, or to the scientifically longest flow path in contrast to the officially defined river. Distance to a mouth, junction or source: I = from the hydrographic mouth of the Weser II = from the mouth of a primary tributary into the Weser III, IV, V, VI = from the higher-ranking mouth of a tributary of a tributary Q, O = from the source or another type of upper end of a receiving water; Q – II, O – S = distance between the source and the mouth of the Weser, the rear end of the sluice H = in Fulda (instead of II) and Werra from their confluence in Hann. Münden Waters of less than 25 km in particular are included if they are to be regarded as part of a longer watercourse.
