Torrential flood risk assessment and environmentally friendly solutions for small catchments located in the Romania Natura 2000 sites Ciucas, Postavaru and Piatra Mare.

摘要: The management of torrential flood risk areas located in natural protected sites requires special approaches. Also, those processes can cause casualties and damage socioeconomic structures (roads, railways, houses, etc.) intercept landscapes, sometimes endangering species habitats. restoration the streambed's stability protection economic objectives affected by floods, imply measures planning. planning are based on use ecological materials technologies with minimal impact environment. article presents a methodology for identifying small river basins high endangered objectives, as well applying this into three Natura 2000 from central Romania (ROSCI0207 Postavaru, ROSCI0195 Piatra Mare ROSCI 0038 Ciucas). Identification was made considering their geomorphological hydrological characteristics vulnerability intercepted socio-economic objectives. Into identified watershed, measurements streambed topography geometric were made. Based hydraulic simulations, maps generated floods 100-year return period. Using these maps, maximum water level determined to highlight each socioeconomics structural objective. In floodplain, nonstructural solutions proposed guiding convenient paths avoid structures.
