20 Development of the Flood Risk Manangement Plan: Preliminary Flood Risk Maps Contain Run-Off-Analysis of the rivers Raab (Pieler, 2008) and Mitterwiesenbach (Ingenos, 2008). 30-year-flood 100-year-flood 300-year-flood

21 Flood Risk Maps reveal the potential adverse consequences associated with a certain flood event

22 Flood Risk Maps reveal the potential adverse consequences associated with a certain flood event

23 Flood Risk Maps reveal the potential adverse consequences associated with a certain flood event

24 Flood Hazard Maps- Gleisdorf The preliminary Flood Hazard Maps (created by the Authorities) contained only the 2D-run-off-analysis of the River Raab. Therefore it was completed by adding the 2D-run-off-analysis of the streams Mitterwiesenbach and Gleisbach.

25 Flood Hazard Maps- Gleisdorf Q 100 Flood Extent

26 Flood Hazard Maps- Gleisdorf Q 300 Flood Extent

27 Development of the Flood Risk Management Plan Stakeholders Discussion about local hazards and damage potential Core Team Ministry of Agriculture, Forestry, Environment and Water Management Ministry for the Environment Construction District Management East-Styria University of Natural Resources and Life Sciences Vienna Ingenos.Gobiet.ZT GmbH, Gleisdorf Extended Team Representatives from the ecological sector Representatives from the economical sector Representatives from the agricultural sector Representatives from the neighbor communities Corporate Town of Gleisdorf Voluntary Fire Brigade Gleisdorf 4 Workshops were held in Gleisdorf with the Agenda: 1. Selection the required measures from the national measure catalog = regional measure catalog 2. Development and application of a prioritization method

28 Development of the Flood Risk Management Plan Categories of the National Measure Catalog PREVENTION REHABILITATION PROTECTION PREPARATION AWARENESS

29 Development of the Flood Risk Management Plan Regional Measure Catalog and Implementation Current situation of implementation of the measures in the pilot region

30 Development of the Flood Risk Management Plan Regional Measure Catalog and Prioritization Prioritization based on 1. relevance and realizability of the measure in the pilot region 2. description of the degree of implementation in the pilot region 3. Evaluation of the remaining measures effectiveness of the measure in the pilot region based on the damage potential feasibility of the measure in the pilot region based on expenditure of time, acceptance by the public, financeability expenses for the implementation of the measure in the pilot region

31 Development of the Flood Risk Management Plan Regional Measure Catalog and Prioritization

32 Development of the Flood Risk Management Plan Regional Measure Catalog and Prioritization

33 Development of the Flood Risk Management Plan Summary and Outlook National Level: The development of Flood Risk Management Plans on the national level is relatively imprecise. Therefore the data quality can be labeled with the MAXO-Code: M Measurement, statement A Approximation, assumption X vague, must be terminated O not terminable An eventual increase of the detailedness can be considered for the 6 yearcycle.

34 Development of the Flood Risk Management Plan Summary and Outlook Regional Level: Many flood protection projects have already been executed - Raab and Mitterwiesenbach - Flood risk adapted building techniques (uplift of the indoor level above Q 100 -events, installation of pumps, removal of valuables and electrical equipment from cellars, etc.) - Flood protection measures at the stream Gleisbach are currently under construction - Deficiencies include - public awareness about the residual risk - implementation of flood aspects in regional development plans - implementation of existing prognosis modell at the river Raab

35 Development of the Flood Risk Management Plan Summary and Outlook Outlook: Usage of the developed regional measure catalog for further decisions in flood protection activities Development of an alert and operation plan for the voluntary fire brigade Concrete information of the public on the existing flood risk and the residual risk (Living behind a flood protection dam and occurance of a Q 300 -event)
