23 Cost Estimation of damages will be implemented during the next phases of the program. Damages: Agriculture (crops, irrigation networks, subsidies to farmers). Environment (sand sediment transported to the fields, fauna etc.). Infrastructure (roads, railways, utility networks etc.). Properties (buildings, plots etc.). Enterprises. Flood Damage Values Estimation per Damaged Area by Return Period Return Period (Years) Damaged Area (m ) Flood Damage Values * ( ) * Flood Damage Values were estimated by taking into consideration the average value (approx. 76,50 per m ) of the compensation granted to farmers, by the Greek Government, following the flood events of 2012.
