17. WATERSHEDS MANAGEMENT (TRANSYLVANIA/ROMANIA): IMPLICATIONS, RISKS, SOLUTIONS

摘要

This work intends to establish ecological rehabilitation, conservation, and management measures for the Olt and Mures Rivers and their main tributaries. These measures will be based on scientific ecological assessment and monitoring of the structure of the river communities (benthic macro-invertebrates and fish) and of the physical and chemical water parameters over the last 6 years. The major categories of human impact on these rivers are highlighted (water and sediment pollution; hydrotechnical works - dams; river channels, marshes and floodplain drainages, cut of meanders, river banks reshaping and embanking, tributary deviations; riverbed mineral exploitation; and riverine land exploitation), and also their consequences on the rivers. Specific ecological rehabilitation measures and optimum conservation measures are described for these rivers.
