Blue Danube
TEN-T extension 2004: Eliminating navigation bottlenecks
Ecologically outstanding stretches
Conflict: TEN-T navigation versus nature
Bavaria: Navigation lobby wants two dams to reach 2.50 meters draught.

Hungary/Croatia/Serbia-Montenegro: A regulation project will threaten the second most important floodplain area on the Danube, the Kopacki Rit

Impacts of ecosystem functions 3/4
Biodiversity Loss due to:
• Habitat destruction
• Habitat fragmentation: Disconnection of side-arms, fragmentation of river-continuum
Example Upper Danube: 58 impounded stretches

Danube and Navigation: Natural- born enemies?
River parameters
Nature DemandNavigation
Demand
hydro-morphology
erosion-sedimentation
uniform
water level high - low stable
water depth deep - shallow homogeneous
water flow fast - slow constant
Dynamics vs. Stability
Status quo: Inland navigation
Old fleet (mostly 20-40 years old):
• High emission rates (NOx, ultra-fine particles, ...)
• Waste water problems, water pollution (e.g. oil)
• Wave wash
Old strategy based on:
• Dredging and deepening of the river channel
• Regulation and channelling
• Damming
