Flood Risk Management in Slovenia
Luka Stravs, M.Sc. Flood Risk Management in Slovenia
introduction, some publicly known data, some observations;
EU Floods Directive implementation in Slovenia (PFRA, APSFRs, FHRMs, FRMP (methodology of the FRMP preparation, catalog of measures, CB method…);
some good flood risk management practices in Slovenia (eVode/eWater platform, Water Management Atlas, free and public LIDAR data distribution for Slovenia); Flood damage data for Slovenia
direct damages after larger flood events in the last 25 years: 1990 cca 580 mio EUR, 1998 cca 180 mio EUR, 2007 cca 200 mio EUR, 2009 cca 25 mio EUR, 2010 cca 190 mio EUR, 2012 cca 310 mio EUR and 2014 cca 255 mio EUR. last 25 years cca 1750 mio EUR (cca 2150 mio EUR); last 10 years cca 980 mio EUR (cca 1200 mio EUR): only direct damages included! quick estimation – 150 mio EUR per year of flood related damages in Slovenia!

Premilinary Flood Risk Assessment – done (22.12.2011), published (22.12.2011) and reported to EC (22.03.2012);
Areas with Potential Significant Flood Risk –61 APSFRs identified (14.02.2013) and reported to EC (21.03.2013);
Flood Hazard and Flood Risk Maps – reported to EC (20.03.2014);

61 APSFRs (130000 inhabitants, 90000 working places, ...)
approx. 50% of all potential flood damages

Examples:
- DAMWARM (cca 3.5 mio EUR); - CRO – SI CBC bilateral FP project (cca 12 mio EUR); - Gradaščica structural FP measures (cca 40 mio EUR); - Selška Sora structural FP measures (cca 21 mio EUR) - detailed mapping; -… FRMP CBA methodology
COSTS - costs of the structural flood protection measures can be calculated (inclusion of annual maintanence and operation costs);
COSTS - estimation of the costs of non-structural flood protection measures can be quite a difficult task ;
BENEFITS - how to assess the benefits of the FP measures? structural – methodology based on reduction of expected annual damage; non-structural - % of risk reduction approximations; FRMP CBA – methodology for the assessment of benefits of flood protection measures - elements at risk FRMP CBA methodogy – Expected annual damage before the implementation of the measure FRMP CBA methodology – implementing the measure CBA mtdlgy–benefit of the FP measure Additional (re)sources (free & publicly accessible and downloadable)

EU 7-year cycle financial pl. 2007-2013, 2014-2020, 2021-2027, 2028-2034
EU RBMP and FRMP 6-year cycle pl. 2010-2015, 2016-2021, 2022-2027, 2028-2033
is EU Floods Directive really just a „daughter“ directive in relation to the EU Water Framework Directive?
WFD measures can be in conflict with FD objectives of reducing existing flood risk as well!
do we really need two management plans for the same river? (hint: integrated river basin management planning!) Thank you for your attention!
