On which river is Dresden, Germany, located?

Dresden is the capital city of the German state of Saxony, and with around 550,000 inhabitants, it is the state's second most populous city after Leipzig. It is the 12th most populous city of Germany, the fourth largest by area after Berlin, Hamburg and Cologne, as well as the third most populous city in the area of former East Germany, after (East) Berlin and Leipzig. Dresden is contiguous with Freital, Pirna, Radebeul, Meissen and Coswig, and its urban area has around 780,000 inhabitants, making it the largest in Saxony.

Dresden is the second largest city on the River Elbe after Hamburg. Most of Dresden's population lives in the Elbe Valley, but a large, albeit very sparsely populated area of the city east of the Elbe lies in the West Lusatian Hill Country and Uplands (the westernmost part of the Sudetes) and thus in Lusatia, while many boroughs west of the Elbe lie in the foreland of the Ore Mountains as well as in the valleys of the rivers rising there and flowing through Dresden, the longest of which are the Weißeritz and the Lockwitzbach.
