Abstract: Excessive rains in the Shkodra Lake and the Drin River basins, and mandatory discharges from the Drin cascade dams, often cause extensive flooding in the northwestern regions of Albania, with many houses, roads and other infrastructure affected. Negative impacts of primary concern are dangerousness for loss of human life, economic loss including property damage, lifeline disruption and environmental damage. Inundation hazard downstream of dams is a critical problem, observed especially during the period December 2009-January 2010. In order to support the hydraulic investigations and the project development for the prevention and reducing the flooding damages, two digital elevation models are built. The first one characterizes the Buna River watercourse, from the Shkodra Lake till the exit sea. It is built using the topographic survey of the Buna riverbanks, and the bathymetric measurements of its watercourse bed profiles. The model will be used mainly to compute the water surface profiles for various pluvial scenarios and various water discharges from the Drin River cascade. The second DTM model is built based on the integrated digital database which includes the topographic and bathymetric surveys undertaken jointly by the Albanian and Montenegrin project teams during the period 2005-2006, and the digital topographic maps of the scale 1:10,000 for a vast flat area downstream the last dam on the Drin cascade. Intention was to support simulation of the water wave spreading, water management scenarios, and flooding damage analysis in this wide and very productive area region.
