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' ^( q e# \$ W7 O& o. Z0 ? 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。8 G) Q* }6 M1 }9 h$ y( a2 y1 J, L1 Q

At 918 meters, it is the longest navigable aqueduct in the world.tvb now,tvbnow,bttvb4 J: t# J2 L) i X1 U- w
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. 8 |. v; M6 ~; _8 B!

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。2 v: n D) ^) D# h, L
