2 We need fulfillment of objectives The economic situation in the European Union is, at least, not in the pink We all need an economic success and visible progressWe need fulfillment of objectivesof the Establishment of European UnionConsolidated version of the Treaty on the Functioningof the European Union Article 9 and 191,PRUDENT AND RATIONAL UTILIZATIONOF NATURAL RESOURCES
3 Based on Common Slovak - Hungarian Monitoring & Synergy Examples of prudent and rational utilization of natural resourcesBased on Common Slovak - Hungarian Monitoring&Specific Danube Conditionswith the goal to support integrated projects with macro regional benefitsimportant for the success of the EU Strategy
4 Bratislava – Budapest Danube Water Management damsThere is no Danube stretch without human intervention The River Danube itself and its surrounding can play the most important role in the Danube Region Strategy, mainly: Navigation improvement, use of hydro-potential, drinking water, water for nature and agriculture, landscape, flood protection, water for sport, recreation, industry, etc.
5 Inundation had been decimated, river flow velocities doubled, Mikovini map (1733) and present state of the DanubeSince the era of theking Bela the IV,1235 to 1270,the water managementconsists, step by step,from straighteningof riverbed,excavations,flood protection,navigation measures,riverbank fortification,closure of branches, etc.Inundation had been decimated, river flow velocities doubled,flow rate is the same. It is no more the natural Danube, but still the Danube with valuable nature close habitats.Alps CarpathiansOriginal floodplainalluvial fan
6 Aquifer; Gravel depth 10 - up to 400 m Basic specific integration points: Danube – water – alluvial fan – navigation – energy Highly permeable extensive aquifer The Danube flows on the top of its fan – flooding danger The Danube water infiltrates into the alluvial aquifer Huge groundwater recharge - excellent water quality Specific inundation, nature close habitatsFlood water levelOriginal inundationpresentAquifer; Gravel depth up to 400 mPermeability – 0.01 m/s
7 Flooded area 1965 in Slovakia Main (imperative) objectiveFlood protection of large areas behind flood protective dikes and reduction of peek flood discharges downstreamFlooded area1965in SlovakiaProtection measures?10 km
8 Large infrastructure projects with the perspective of all mutual synergies such as: protection against flood, water transport, use of hydropower, water supply, agriculture, silviculture, hygiene and water born diseases, recreation, reduction of greenhouse gas emissions, etc., according to our experience, evaluate in advance environmental impacts and determine, effective and safeguard measures. Financial and social effect should not be neglected. Some examples:

10 The Danube Floodplain supplied with flowing water is protected area Flowing water means better self purification processes

21 Objectives – Benefits – Impacts Community – Nature resources ? IntegrationSynergy ?Integration of the Community environmental policy with the sustainable development and prudent and rational utilization of natural resources, using available scientific and technical data, monitoring, regional conditions, and proper transposition of WFD in conformity with the European Community PolicyTTT Project
22 Slovak Republic is offering, as an input into the Danube Region the TTT Project, which will contribute tofollowing objectives of the European UnionThe TTT project:Creates conditions for all kinds of connectivity, lies in the middle of the Danube Region, and almost in the middle of the EUCreates conditions for exploration and construction of waterworks sites for piping and use of high quality potable groundwater in the extremely large quantities over large EU territoryExpects to improve navigation in the Danube in the section Hainburg - Bratislava, hydraulically connecting the Danube Navigation Project East of Vienna with the Hydropower plant GabcikovoAllows the use of the Danube hydro-potential, approximately 600 GWh per year.Allows protection of the groundwater quality issues at Bratislava.
23 The TTT project:Solves definitively the flood protection at Devin (from Hainburg to Bratislava) and at the mouth of the River Morava.Allows navigability connection between the Danube and the Morava River, and improves the navigation security in this sectionPreserves the Morava River in present state, and into the bargain, allows navigation from the Danube to the TTT project via navigation channel.Ensures the flood protection downstream the river Morava from the TTT project area, down to the River Danube, using water management of the River Moravia and the shipping channel.Offers hydraulic possibility to solve environmental problems in the protected areas in the lowland of Záhorská nizina, negatively affected after the World War II.Supports protection and care of the ecosystems of the protected areas, or minimize the previous and present adverse impacts.
24 The TTT project:Strongly supports the economy, trade, and jobsStrongly supports the infrastructure of the territory and small SME projects, including housingStrongly supports the knowledge society, knowledge-based organizations, educations, etc.Supports multi cultural developmentCreates opportunities to construct reverse pumping storage power station to support storage of wind and solar energyIn many aspects, supports measures to combat climate change (use of hydro-potential, transfer of road transport to rail and water, reducing traffic in light of the TTT project position in the middle of Region and the EU), and by various environmental protection measures.
25 Results of Joint Slovak – Hungarian Environmental Monitoring, are described in this anniversary publication.Monitoring is dealing with environmental conditions and processes already influenced by hydraulic structures and water management.Scientific research and interpretation of relations among water management and responds of the surrounding environment will help to prepare quantitative and qualitative prognoses based on previous long term development (causal relations) and further comprehensive modeling of various processes.
