It only needs to be designed to withstand the weight of the water! os.tvboxnow.com4 z# M- u+ d+ \2 D
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 / P* @0 i k, Gos.tvboxnow.com .

At 918 meters, it is the longest navigable aqueduct in the world.os.tvboxnow.com ^6 ~; f3 S; N/ `8 X% l( `
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. " u( M+ @% [" c+ _.
