  14. BALWOIS 2010, 25-29 May, Ohrid, Macedonia CONCLUSIONS alfa.i (2006) • The floods are overestimated • The overestimation imposed reconstruction that includes: - construction of additional culvert under the runway - construction of pumping station at N2 - diversion of pumped water to Magura River - diversion of culverts D2 and D3 to Henc River

  15. BALWOIS 2010, 25-29 May, Ohrid, Macedonia FCE (2008) • Hydrological and hydraulic modeling was carried out • The existing storm sewer system enables safety transfer of flood • There is no need of additional culvert under the runway • Maintenance of the existing storm sewer system is out of issue • Management of the existing storm sewer system is out of issue • Risk assessment could not be performed due to lack of data

  17. Evaluation formulas: Vegetation index=vegetation cover/total land area (%) Population density=total population/total land area (persons/km2) Resistance damage index=amount of damages/GDP of normal year (%) Crop damage area=crop damage area caused by heavy rainfall (ha) Flood damage index (FDI)=Ip+Ih+Ie Ip - persons damage number Ih - houses damage number Ie - economic losses
