The Elbe is one of the major rivers of Central Europe. It rises in the Giant Mountains of the northern Czech Republic before traversing much of Bohemia, then Germany and flowing into the North Sea at Cuxhaven, 110 kilometres northwest of Hamburg. Its total length is 1,094 km (680 mi).
The Aller is a 215-kilometre-long (134 mi) river in the states of Saxony-Anhalt and Lower Saxony in Germany. It is a right-hand, and hence eastern, tributary of the Weser and is also its largest tributary. Its last 117 kilometres (73 mi) form the Lower Aller federal waterway (Bundeswasserstraße). The Aller was extensively straightened, widened and, in places, dyked, during the 1960s to provide flood control of the river. In a 20-kilometre-long (12 mi) section near Gifhorn, the river meanders in its natural river bed.
The Havel is a river in northeastern Germany, flowing through the states of Mecklenburg-Vorpommern, Brandenburg, Berlin and Saxony-Anhalt. It is a right tributary of the Elbe and 325 kilometres (202 mi) long. However, the direct distance from its source to its mouth is only 94 kilometres (58 mi). For much of its length, the Havel is navigable; it provides an important link in the waterway connections between the east and west of Germany, as well as beyond.
The Saale, also known as the Saxon Saale and Thuringian Saale, is a river in Germany and a left-bank tributary of the Elbe. It is not to be confused with the smaller Franconian Saale, a right-bank tributary of the Main, or the Saale in Lower Saxony, a tributary of the Leine.
Bad Schandau is a spa town in Germany, in the Sächsische Schweiz-Osterzgebirge district of the Free State of Saxony. It is situated on the right bank of the Elbe, at the mouth of the valley of the Kirnitzsch and in the area often described as Saxon Switzerland.
Oste is a river in northern Lower Saxony, Germany with a length of 156 km (97 mi). It is a left tributary of the Elbe.
The Black Elster or Schwarze Elster is a 179-kilometre (111 mi) long river in eastern Germany, in the states Saxony, Brandenburg and Saxony-Anhalt, right tributary of the Elbe. Its source is in the Upper Lusatia region, near Elstra.
The Aue is a river in northern Germany in the district of Stade in Lower Saxony. It has a length of about 30 km (19 mi).
The Ise is a 43 km (27 mi) long, almost natural river of East Lower Saxony and Saxony-Anhalt, Germany. It crosses the district of Gifhorn from north to south and discharges into the Aller at Gifhorn itself.
The Geeste is a river in northwestern Germany, running through Lower Saxony and Bremen. It is the most downstream tributary of the River Weser and joins it near Bremerhaven. The Geeste rises in Hipstedt in the district of Rotenburg (Wümme) ten kilometres west of Bremervörde and drains a large part of the old district of Wesermünde.
The Elbe–Weser waterway or Elbe–Weser shipping channel is a short-cut between the rivers Elbe and Weser in North Germany which is part-canal and part-river. It has a length of 54.7 kilometres (34.0 mi) and is designed for smaller coastal vessels. It includes some 60 kilometres (37 mi) of canal dykes and 45 kilometres (28 mi) of canal paths. The channel starts in Otterndorf with the Hadeln Canal, then becomes the Bederkesa-Geeste Canal from the town of Bad Bederkesa to the River Geeste, the final leg of the shipping channel, which flows into the Weser at Bremerhaven. It is owned by the state of Lower Saxony, maintained by the NLWKN from its Stade office. Today they just look after maintenance of the drainage system, because the economic element of the canal – commercial shipping which was particularly thriving in the late 1960s – declined increasingly from 1973 onwards and today hardly exists at all. Nevertheless the waterway is still used by smaller yachts as a short cut between Elbe and Weser.
The Abelitz is a river of Lower Saxony, Germany, in East Frisia. It is about 20 kilometres (12 mi) long and flows from Marienhafe to its mouth on the Alte Greetsieler Sieltief. This type of river that drains the low-lying polders through a sluice in the sea dyke is also known locally as a Tief and is often the course of an old creek between mudflats.
Lühe is a river in northern Germany in the district of Stade in Lower Saxony, Germany.
The Black Pockau is a river of Saxony, Germany, in the Ore Mountains. It is a left tributary of the Flöha. This virtually unspoilt wild stream with a length of 33 km (21 mi) is known for the picturesque gorge in its middle reaches.
The Sebnitz is the left, larger headstream of the Lachsbach and runs through both the Czech Republic as well as the German Free State of Saxony. The upper section in the Czech Republic is known as Vilémovský potok in Czech and Wölmsdorfer Bach in German.
Lake Cachi is an artificial lake in central Costa Rica created by the Cachí Dam, an arch dam north of Tapantí National Park, to the east-southeast of Cartago in Cartago Province. The main town is Cachí, away from the east bank of the lake. Built in the 1970s, it was one of the first hydroelectric projects in Costa Rica. It has an installed capacity of 102 MW with three units of 34 MW capacity each.
The Niederelbe is a 108 kilometers long section of the river Elbe, from western Hamburg downstream to its mouth into the North Sea near Cuxhaven. Starting at Mühlenberger Loch near Finkenwerder, Hamburg, it gradually widens from 2 km (1.2 mi) to 18 km (11 mi). Once passing the Hamburg state border, the Niederelbe also forms the border between the states of Lower Saxony and Schleswig-Holstein.
The Unterelbe or, in English usually the Lower Elbe, refers to the lower reaches of the river Elbe in Germany influenced by the tides.
The Schwingesperrwerk is a man-made movable barrier located on the Schwinge at its confluence with the Elbe near Stade, Germany. It is part of the flood control program for the Lower Elbe tidewater region, from the weir in Geesthacht to the mouth of the Elbe where it flows into the North Sea. Engineers constructed the Schwingesperrwerk after a storm surge caused severe floods in the region in 1962.
The Upper Noteć Canals are an aggregate of inland water channels in Kuyavian-Pomeranian Voivodeship, Poland. They stem from the upper part of the Noteć river, north of Gopło lake, and mouth at their northern point into the Bydgoszcz Canal, west of the city territory. These canals have been put into operation between the 1770s and the 1880s and are still partly navigable today.
