1 CONFERENCE Breaking fresh ground in protecting Alpine Environments - Flood Risk Management Plans, in Graz/Austria Rudolf HORNICH Styrian Federal State Government Department 14

2 Host: Platform of Natural Hazards - PLANALP (working group of the Alp Convention), together with Austrian Ministry of Life and the Office of the Styrian Government Motivation: specific problems with FRM in the Alps - no similar activities up to now that covered this topic Venue: Graz, Austria 125 participants 12 different countries (Malta - Latvia, Norway) 11 presentations

4 Vb - track Alps are often affected by the European general weather situation for example the Vb-weather situation.

5 Economic damages Floods, debris flows, landslides and rockfalls indexed to 2009) Source: Flood catastrophes have been the most frequent natural disasters in recent years in the alpine area.

6 Specific problems regarding flood risk management in alpine catchment areas: Bed load and sediments, drift wood Morphodynamcis

7 FD 2007/60/EC: Art. 2 Specific problems flood means the temporary covering by water of land not normally covered by water. This shall include floods from rivers, mountain torrents,. Bed load The discharge processes are affected by sediments and bed load material, which not only cause great damage but also cause problems with cleanup efforts due to the huge amounts of rubble and debris mass.

8 Specific problems Drift wood Huge amounts of driftwood, that is carried along, aggravate the flood situation. Log jams lead to uncontrolled discharge and, consequently, to great damage in residential areas.

9 Specific Problems Extreme floods and river morphology morphodynamics Trisanna, Galtür, Austria, 2005 Source: Habersack & Krapesch, 2006

11 Specific problems regarding flood risk management in alpine catchment areas: Bed load and sediments, drift wood Morphodynamcis Developement of settlements limited space, rising damage potential Tourism

12 Specific problems settlement source: Rudolf-Miklau Dynamic development of municipalities in Alpine areas due to tourism and economic growth, also in areas endangered by natural hazards. An enormous increase of damage potential in hazard-prone areas took place within the last decades.

14 Presentations: Key-note speech: THE EU FLOODS DIRECTIVE PROGRESS AND CHALLENGES Mark Adamson (IR) representing WGF introductory speech: Specific problems regarding flood risk management in alpine catchment areas Rudolf Hornich (A) Links between the Floods Directive and the Water Framework Directive Clemens Neuhold (A)

15 Presentations member states of the Alp Convention : On the way to the Austrian Flood Risk Management Plan: methodology and challenges Heinz Stiefelmeyer (A Flood Risk Management and Floods Directive (2007/60/EC) Implementation in Slovenia Luka Stravs (SLO) Flood Risk Management Plans Ricardo Rigon (I) Flood Risk Management Plans Jean Michele Helmer, Marie Pierre Meganck(F) Torrential flood risk management in Bavaria Andreas Rimböck (D) Flood Risk Management in Switzerland - Olivier Overney (CH) Public participation in flood risk management Therese Stickler (A) Flood risk management plans and contingency planning: Challenges and chances from a disaster prevention perspective - Eva Mayer (D)

16 Conclusions: In line with the elaboration of FRMP in Alpine areas great significance is given to the measures of LUP There is a need for creation of legal framework requirement for protection, preservation and improvement of existing retention areas The first cycle of the development of FRMP poses a lot of questions. Therefore the change of experiences between the member states is a core requirement. Apart from technical safety measures in Alpine regions FRMP should set a high value on non structural measures used for protection. Flood risk management plans with regard to the specific circumstances in alpine regions are a crucial basis for the security and future development of alpine living spaces.
