Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loadedtvb now,tvbnow,bttvb/ ^/ L, e' X0 j6 ^0 p9 d' s 7 a' E2 @5 `6 B1 x( J6 N$ J$ p1 QTVBNOW 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。5.39.217.77:8898, z7 y/ ]9 @, n5 N2 G The Incredible Magdeburg Water Bridge in Germany( g, X( \" `6 X7 T* E( |0 [" V
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. # X* e9 ]0 \, p5 Y" q1 S1 iThe 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. 公仔箱論壇+ u6 \0 J L+ ^% \

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. 5.39.217.77:8898- q. S' f3 g5 n2 F! Y x2 C
