It only needs to be designed to withstand the weight of the water! / s) Q# \. n9 itvb now,tvbnow,bttvbWhy? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 3 m2 w/ W! Q P3 ~/ }5 q. q公仔箱論壇 1 Q( _/ v1 W: I; k$ f Z公仔箱論壇 : z4 r! A( @4 \5 m% UThe Incredible Magdeburg Water Bridge in Germany / m4 w' A$ E+ b公仔箱論壇The Magdeburg Water Bridge is a navigable aqueduct in Germany that connects the Elbe-Havel Canal to the Mittelland Canal and allows ships to cross over the Elbe River. At 918 meters, it is the longest navigable aqueduct in the world.* `5 l! `+ `/ x5 e7 M
The Elbe-Havel and Mittelland canals had previously met near Magdeburg but on opposite sides of the Elbe Ships moving between the two had to make a 12-kilometer detour, descending from the Mittelland Canal through the Rothensee boat lift into the Elbe, then sailing downstream on the river, before entering the Elbe-Havel Canal through Niegripp lock. Low water levels in the Elbe often prevented fully laden canal barges from making this crossing, requiring time-consuming off-loading of cargo. 0 H- |5 W, g1 Y& x

Construction of the water link was started as early as in the 1930s but due to the World War 2 and subsequent division of Germany the work remained suspended till 1997. The aqueduct was finally completed and opened to the public in 2003. TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。, p9 d- i7 d8 \" x4 c
