Run of Giehler Bach and Hamme by Langer Heide into Teufelsmoor to mouth in Lesum

Template: Infobox River / Obsolete

The Hamme, the 48 km long, right or northern source river of Lesum, a tributary of the Weser River in northern Lower Saxony.

It is connected by the Hamme- Oste- channel with the Oste in the northeast near Bremervörde and drains the Teufelsmoor between Worpswede and the county town of Osterholz- Beck. In Ritterhude it flows together with the much larger Wümme and thereafter reaches as Lesum the Weser.

River

The upper reaches of the Hamme is called Giehler Bach. The Giehler creek rises in the north-east of Long Heide Osterholz- Beck, a moraine plateau at an altitude of about 45 m above sea level. NN, which is also the headwaters of numerous other Geestrand streams (eg Drepte, Scharmbecker Bach, Schönebecker Aue, Wienbeck ). The "source" to designated place is the outflow of several drainage ditches of the agricultural plateaus.

From the ridge of, a terminal moraine of the Saale ice age, the Giehler creek flows northeast and descends to a few kilometers between the towns of Hülseberg and Freißenbüttel to a level of about 15 meters above sea level In Ohlenstedt water flows to from the Ohlenstedter source lakes, and the river running through gently descending the Municipality Hambergen to the Springmoor at Giehlermühlen ( Vollersode ) (5 m above sea level ).

From there, the river descends only minimally to the Devil's Moor, where it is finally in Giehler Moor in cattle Specken (4 m above sea level. NN ) to Hamme. There is also the inflow of Hamme- Oste- channel ( Kollbeck ). Extremely low flow, the Hamme now flows south through the glacial valley named after her.

Between the former peat Bornreihe and Hüttenbusch through you head Worpswede, where the three left tributaries Rummeldeisbeek, Schmoo and Umbeck lead. A few kilometers upstream flows from the right to the Beek, west drained most of the marshland of Hamme. Shortly before the opening of the Beek in the Hamme lies the nature reserve of width water, the largest remaining standing water throughout the lowland region. From here the Hamme direction Ritterhude flows past in a southwesterly direction to Osterholz- Beck.

In the 19th century this part of the Hamme has been straightened, and the numerous meanders were pierced at a total of seven points, so that the river has been reduced on this stretch of 9 km to 4.3 km. Behind built in 1876 lock in Ritterhude through which the Hamme is held tides free, meets the Hamme near the city limits of Bremen on the Wümme and forms with it the influenced by brackish water Tidefluss Lesum, which flows 10 km below into the Weser.

At a length of 48 kilometers of the river overcomes a difference in altitude of about 45 meters.
