Rhine drops below crucial level, impacts river transport
The Rhine river in Germany on Aug. 12 fell below a key waterline level used as a reference for judging its accessibility for shipping.
The water dropped below the 40-centimetre (15.7-inch) reference level in Kaub, a noted bottleneck for shipping where the Rhine runs narrow and shallow.
That level is considered necessary for much of the transport along the river.
