A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 7 w# E# ~, y- m + P+ O9 k9 w! {: k' y2 p, m3 E' \tvb now,tvbnow,bttvbTVBNOW 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。+ _9 ?& E u+ X6 k' O0 U The Incredible Magdeburg Water Bridge in Germanywww1.tvboxnow.com* m/ B6 x0 u) E0 s0 J& [
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.( _( j; }4 `+ e! j9 p
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. 公仔箱論壇# C$ j6 W( W! T6 v/ s9 e
