Fig. 3.19 Hydropower dam on the Danube River near Jochenstein, Germany. The river here drains
approximately 50,000 km
2 and is approximately 400 m wide at the dam
associated lateral connectivity within the river corridor, thus limiting the effectiveness of efforts to reconnect the main channel with secondary channels and the floodplain along portions of the Danube. There are also some very large dams within the
Danube, particularly the Djerdap I and II dams in Romania, built in 1970 and 1984,
respectively, for hydropower (Wohl 2011). These dams effectively ended the migration of fish between the upper and lower portions of the Danube river network.
