Case studies
Tuesday, 19 January 2010 10:12

Better involvement and more openness as well as better policies, regulation and delivery have been identified as key objectives by the White Paper on European Governance, launched by the EC in 2001. Risk governance principles like stakeholder involvement have been integrated in the ISDR, as endorsed in January 2005 in the Hyogo Framework for Action. In order to prove this conceptual framework, three different river basin districts are partners into the IMRA project to carry out case studies. They are:

  • a mid-Europe hilly land river basin district, densely built-up, mainly prone to winter floods and flash floods: The river Wupper (Germany);
  • an alpine river basin, prone to flash floods and debris flows: the river Möll (Austria);
  • a Mediterranean river basin, prone to torrential floods: the river Chiascio (Italy).


Case study River Wupper (Germany)


  • Catchment area: 813 km2
  • Location: North Rhine-Westphalia,east of Düsseldorf and Cologne
  • Tributary of the Rhine
  • The riverbed lies between 441 m and 34 m
  • Due to massive floods at the beginning of the 20th century, technical measures including dams were developed
  • Since that more local flash floods
  • Lack of risk awareness


   Case study River Möll      (Austria)


  • River basin: 1.105 km2
  • Location: Carinthia and a small part of East Tyrol
  • Tributary of the Drau
  • The riverbed lies on a sea level between 1.290 m and 550 m
  • After massive floods in the 1960ies huge amount of technical measures
  • In contrast to other Austrian regions only small floods or landslides in 2002, 2005 and 2006
  • Awareness decreased
  • But: risk of extreme floods still exists

Case study River Chiascio (Italy)


  • Catchment area: 727 km2
  • Location: Apennine ridges
  • Tributary of the Tiber
  • The river originates at an altitude of 850 m above sea level and after 95 km it flows into the Tevere river
  • The challenge future is to increase awareness of local populations and share the need for virtuous behaviour
