Hamme (в его верхней части Giehler Bach ) находится 48-километровый (30 миль) реки в Германии , Нижняя Саксония , к северо-востоку от Бремена . Его источник находится к северу от Остерхольц-Счармбека . Он течет через мавры к северо-востоку от Бремена под названием Teufelsmoor и встречает реку Вумм в Риттерхаде . Из этого соединения река называется Lesum . Lesum течет в реку Весер в Бремен-Вегекак .
На реке Хамм есть много клубов водного спорта, например, Wassersportclub Hamme EV (Watersports-Club Hamme), Ruder-Vverein Osterholz-Scharmbeck из 1901 EV (гребный клуб Osterholz-Scharmbec (Парусный клуб Хамм).
Курс
[ редактировать ]Верхние достижения Хамма называют Giehler Bach (Giehl Stream). Giehler Bach начинается в пустоте, на северо- востоке от Остерхольц-Шхармбека, гео- плато на высоте около 45 м над уровнем моря (NN) , что также является источником многих других потоков героя (например, Drepte, Schambecker Bach, Schönebecker Aue и Wienbeck). Спорт, обозначенный как «источник», является выходом нескольких дренажных каналов на плато, которое используется для сельского хозяйства.
From this geest ridge, a terminal moraine from the Saale glaciation, the Giehler Bach flows northeastwards and descends within a few kilometers between the villages of Hülseberg and Freißenbüttel to a height about 15 m above sea level (NN). Near Ohlenstedt it is joined by waters from the Ohlenstedter Quellseen lakes and the river, falling very gently, then flows through the collective municipality of Hambergen to the Springmoor near Giehlermühlen (Vollersode) (5 m above sea level).
From there, the stream descends very gently to the Teufelsmoor, where it is finally discharges into the Hamme into the Giehler Moor near Viehspecken (4 m above sea level). It is also joined by the Oste-Hamme Canal (Kollbeck). Flowing very slowly, the Hamme now heads south through the glacial valley named after her.
Between the former moor colonies of Bornreihe and Hüttenbusch the river now continues in the direction of Worpswede, where it is joined by three left-hand tributaries, the Rummeldeisbeek, Schmoo and Umbeck. A few kilometers upstream the Beek enters from the right, draining most of the moors west of Hamme. Near the mouth of the Beek on the Hamme is the picturesque nature reserve of Breites Wasser, which is the largest remaining lake in the lowland region. From here the Hamme flows in a southwesterly direction past Osterholz-Scharmbeck towards Ritterhude.
In the 19th century, this part of the Hamme was straightened and the numerous meanders were cut at a total of seven places, so that the length of the river was reduced from 9 to 4.3 km. Behind the locks in Ritterhude, built in 1876, which keep the Hamme tide-free, the Hamme joins the tidal river of the Wümme near the city limits of Bremen and together they form the salt-waters of the Lesum, which enters the Weser 10 km downstream. The old branches of the river were mainly preserved as one-sided confluences with the Hamme. A remaining part of the so-called Altarm 3 ("Old Arm no. 3") southeast of Scharmbeckstotel was de-sludged in 2007 as part of the Hamme Depression Nature Conservation Project and in 2008 a sill was added to prevent it from running empty at low water. At the end of January 2020, after three months of construction, the 230-metre-long stretch of this waterbody that had been filled in was dug up again over its length and connected to the Hamme.[5]
The total length of the river is 48 km and it descends through about 45 m.
