6 Lower Danube and Danube Delta CASE STUDY

7 The Danube River Basin Management Plan (2009) concluded that 93% of the Danube River is at risk or possibly at risk of failing WFD due to hydro morphological alteration and 80% of the Danube River Basin District s (DRBD) former wetlands/floodplains are disconnected, largely for agricultural uses and river engineering works for flood control, navigation and power generation. In response, in the Lower Danube Floodplain, Romanian Ministry of Environment proposed an adaptation scenario for climate and land-use change (REELD).

32 Before all, must seek, through our work to be able to put a value of this area as more of this land and not leave areas so large between bank and dyke, to be condemned to remain unproductive, except of course the areas that are strictly necessary for water flow during large flood. This can not be achieved, in another way than creating in the edge of the river from a distance to distance a series of basins, besides permanent wetlands, that we have shown that preserved and arranged, which alternate with land reserved for agriculture and were the river water can flood.

33 According to existing data and hydraulic scenarios drawn up on the surface of the total embanked precincts of the Danube Floodplain - 445,000 ha, results 3 categories of use in the future: 43.3% for the remaining precincts for agriculture; 40.8% areas used as mixed (agricultural / polders and water storage); 15.9% areas for renaturation to create wetlands.

36 Conclusions UAV is a valuable tool that can examine and describe hydro morphology in wetlands needs for ecological restoration. The application of UAV provides a methodological contribution and quantitative analysis to drill first the relationship between geomorphological processes and the degree of convolution of the arm and can thus develop scenarios of its development. Correlation of the flow dynamics with the variation of climate which still gives headaches to the researchers can be demonstrated and modeled by UAV technology. This quality can transform in the very important decision support instrument in vulnerability neighboring areas. The ecological restoration need data of the natural state and UAV using is also confirmed by analysis and comparing the three temporal stages (analysis Hartley's Map 1870, orthophotomap 2011 and shortterm scenario).
