Key features of the case study
Site description
The Dunavat - Dranov region is a large depression, filled with peat, between two minor Danube distributaries. Both distributaries, presently the Dranov and Dunavat canals, flow from the Sf. Gheorghe Danube branch to the former Razim lagoon. The region was profoundly influenced by human activity in the 20th century. The Razim lagoon was cut off from the Black Sea and was changed into a fresh water reservoir with a raised water level. The isolated central peat area in the Dunavat - Dranov region was opened up to boats and to river water by an artificial canal system. The incoming river water from the Danube underwent a strong increase in nutrient contents, causing eutrophication of valuable mesotrophic water systems. Fish farm basins were constructed with ring dikes and pumping stations, a high-tension electric power line and some fish collection platforms with management buildings. The reed beds and peat soil in the fish farm basins were destroyed, causing a.o. a land subsidence with 0.5 - 1.0 meter.
