Int. Roundtable on Transboundary Waters Management, 15-16.12.2011, Marina Babic Mladenovic

  1. 1. International Roundtable on Protection and Sustainable Use of Transboundary Waters in Southeastern Europe, Zagreb, 15-16 Dec 2011 THEMATIC BLOCK 1- Emerging Challenges, Extreme phenomena-Floods Dr Marina Babić Mladenović INSTITUTE “JAROSLAV ČERNI” - BELGRADE
  2. 2. A few cycles of intensivesnow and intervals withunusually high airtemperatures Water equivalent of snowabove average values
  3. 3. Coincidence of flood on theDanube and Tisza river, causedthe hi h tth highest water l t levels ever lrecorded
  4. 4. Example of 2006 Flood

  6. 6. Successful flood defence, very expensive 10 M €240 000 ha flooded – unprotected zones (between levees) andarrable land flooded by excessive inland waters - damage 30 M €State of emergency in 10 municipalities along the Danube and TisaTransboundary cooperation◦ Good cooperation between the HMS Serbia and HMS of other DRB countries – hydrological data and forecasts◦ Flood release through the Iron Gate 1 and 2 dams was strictly according to RO-RS bilaterally agreed rules of operation◦ ICPDR report
  7. 7. Example of 2010 flood - DRB
  8. 8. Example of 2010 flood - Serbia - Unfavorable hydro-meteorological conditions in the first half of 2010 o Prolonged but not extreme rainfall o Extremely wet conditions – saturated soil - Flood waves registered on 39 large and medium rivers, and numerous torrents - Repeated flood waves p - Flood damage - mainly on unprotected areasJan +Jun/July +Dec June Dec 2009 - Feb 2010 Dec June Floods caused by Feb - extreme hydro- hydro- Feb - April April meteorological phenomena
  9. 9. Example of 2010 flood - SerbiaCause: rapid snowmelt + rainfall (up to 15 mm/day) + very saturated soil mm/day)Consequence: 300 houses flooded in unprotected zoneActivity: Reconsideration of flood risk + local flood protection measures
  10. 10. The hydrological situation in 2010 was highly unfavorable, withrepeated floods on nearly all national and international rivers -example of the Sava River, where floods occurred at the verybeginning of the year, in the summer, and in December 2010.Flood defense activities l t d f 185 dFl d d f ti iti lasted for days – mostly emergency tlflood defense was in force and in some areas the emergencysituation was declaredTransboundary cooperation◦ International data and forecast exchange in the region need to be improved – especially in the Drina river basin◦ ICPDR report
  11. 11. Example of 2010 flood – Drina river basinThe largest and most importanttributary of the Sava RiverCatchment area 20320 km2 Montenegro 31,5% M t 31 5% Serbia 30,5% Bosnia and Herzegovina 37% g % Albania 1%
  12. 12. Example of 2010 flood – Drina river basinDrina, Tara and Piva and several have End of November/beginning of December 2010snow-rain regime - largest flows occur in - strong cyclone activity in Montenegro andMay and April. East Herzegovina - causing heavy rainfall, strong southerly winds, and very highMelting of snow in the mountains is usually temperatures for the time of year.gradual – disastrous floods are notfrequent. q Snowmelt and abundant rainfall (100 200 mm (100-200 in 3 days) led to a difficult flood situation in the Drina river Basin. Flood waves on the Drina tributaries (Piva, Tara, Cehotina, Lim and Jadar) and the main course were exceptional.
