Flood Risk Management in

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);

 Flood Risk Management Plan (work in progress). Preliminary Flood Risk Assessment for Slovenia http://www.mop.gov.si/fileadmin/mop.gov.si/pageuploads/podrocja/voda/predhodna_ocena_popl avne_ogrozenosti.pdf 61 APSFRs in Slovenia (42 APSFRs in the River Basin / 51 APSFRs in the Danube River Basin) PFRA data and APSFRs in Slovenia

61 APSFRs (130000 inhabitants, 90000 working places, ...)

approx. 50% of all potential flood damages

FRMP – Savinja River Basin (monit.) FRMP – Savinja River Basin – projects (ideas, on-going ones, expected results) FRMP – Savinja River Basin – FP projects for each basin (details) FRMP – Savinja River Basin – FP projects for each basin (details)

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 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!
