4.3.1. Case study: Danube, Rhine, and Rhône rivers heavily impacted by hydro-morphological pressures

Source: ICPDR, 2010 and Umweltbundesamt, 2010

Like many other European rivers, the Danube and Rhine are heavily influenced by human activities including intensive navigation and habitat modification by hydraulic engineering. The natural structure on many stretches of the rivers has been changed, including their depth and width, flow regimes, natural sediment transport and fish migration routes.

Dams and reservoirs have been built in nearly all mountainous areas and some lowland regions of the Danube Basin and navigation channels, dykes and irrigation networks are widespread in the lowlands along the middle and lower reaches of the river.

more than 80 % of the Danube is regulated for flood protection, and about 30 % of its length is impounded for hydropower generation;
about half of the Danube tributaries are used to generate hydropower. The generation capacity of all the hydropower plants in the Danube Basin is almost 30 000 MW;
more than 700 dams and weirs have been built along the main tributaries of the Danube;

Suggestion to include (draft) results and a reference to ongoing ICPDR Activity „Hydropower and Water Management“ in the Danube River Basin:
- 1st ICPDR Workshop on Hydropower and Water Management was organized from 21-22 February 2012, Timişoara, Romania
- Currently work ongoing on „Assessment Report on Hydropower Generation in the Danube Basin“, which will approved in the year 2012
- “Common Guiding Principles on Hydropower Development in the Danube Basin” including case studies and good practice examples currently to be elaborated and to be finalized in 2013

  Dear Andi,
  
  Any docs you could send would be appreciated.
