Assessment of flood risk and economic impact, Drin river basin, Balkans (2019-08-02)

Activation date: 2019-08-02
Event type: Flood

Activation reason:
The specific activation focuses on deepening the analysis concerning the occurrence of floods within a transboundary AOI that corresponds to the Drin catchment area and more specifically to the part that extends into four countries, namely Albania, Kosovo, the Former Yugoslavian Republic of Macedonia and Montenegro.The service and the products aim to serve the scope of the Drin River Cooperation agreement on sustainable management of water resources in the Drin catchment area through providing information relevant for risk preparedness (hazard, historical floods and economic risk assessment) and sustainable development (economic assets mapping, economic risk assessment).Historical Analysis of Floods[HTML_REMOVED]Events of 12/2004 - Bar, Cetinje, Danilovgrad, Nicksic, Podgorica, ShkodraComprehensive knowledge of a number of disasters that occurred in the past is provided through the spatial extent of the floods, mainly linked with rainfall, and assessment of their impact on existing assets, as well as information on Land Use/Cover and existing assets and infrastructures.To efficiently support [HTML_REMOVED]informed[HTML_REMOVED] decisions on flood risk management activities and planning of prevention, protection and preparedness measures, through accounting for the area characteristics, the flood hazard was assessed.Flood Risk Mapping [HTML_REMOVED] Hazard Assessment[HTML_REMOVED]Towards reducing the adverse consequences of flooding for both population and economic activity, flood Hazard assessment was implemented within the Drin catchment area.Due to the characteristics of the Drin river basin, for the estimation of the maximum flood extent a morphological approach was deployed for the catchment area upstream of Skadar lake (based upon the Flood Susceptibility Index/FSI), while a hydraulic modelling was implemented for the Buna river, within a mainly flat area of the AOI, from the Skadar lake to the Adriatic Sea (TELEMAC-2D model through using a very high-resolution DEM).Flood Risk Mapping - Economic Risk Assessment[HTML_REMOVED]The overall economic risk assessment was implemented through the use of the[HTML_REMOVED]RASOR platform. Hazard assessment data, economic assets and vulnerability information were accounted to generate a percentage damage of the single asset types. The economic risk was then evaluated on the basis of the economic value information of the asset type/category per square metre, and the effective area occupied by each category.[HTML_REMOVED]
