It only needs to be designed to withstand the weight of the water! tvb now,tvbnow,bttvb+ H0 t* g) d! z7 r5 O8 q
Why? A ship always displaces an amount of water that weighs the same as the ship, regardless of how heavily a ship may be loaded 5 H& [5 l3 w7 w! mtvboxnow.com # f/ X, l% C! l" m6 m4 Y N7 CTVBNOW 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。 ; z7 m; N/ \0 g!

U* J }$ l7 R* _' Jtvb now,tvbnow,bttvbThe 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. $ k3 ~3 `$ C. f1 N, V% l+ eThe 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. & p, t) i9 Y, U; S+ J.
