2 INTEGRATED UTILIZATION OF NATURAL RESOURCES Synergy examples based on Joint Slovak-Hungarian Monitoring INTEGRATED UTILIZATION OF NATURAL RESOURCES Synergy examples based on Joint Slovak-Hungarian Monitoring Prepared for Plenipotentiary of the Slovak Republic for Construction and Operation of Gabcikovo-Nagymaros Hydroelectric Power Project Prof. Igor Mucha, Dr.Sc., RNDr. Dalibor Rodák, PhD., RNDr. Zoltán Hlavatý, PhD., RNDr. Ľubomír Banský, PhD. GROUND WATER Consulting, Ltd., Slovak Governmental Plenipotentiary Expert Group DANUBE REGION STRATEGY

3 The economic situation in the European Union is, at least, not in the pink We all need an economic success and visible progress We need fulfillment of objectives of the Establishment of European Union Consolidated version of the Treaty on the Functioning of the European Union Article 9 and 191, PRUDENT AND RATIONAL UTILIZATION OF NATURAL RESOURCES

4 Synergy Examples of prudent and rational utilization of natural resources Based on Common Slovak - Hungarian Monitoring & Specific Danube Conditions with the goal to support integrated projects with macro regional benefits important for the success of the EU Strategy

5 There 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. Bratislava – Budapest Danube Water Management dams

6 Mikovini map (1733) and present state of the Danube Since the era of the king Bela the IV, 1235 to 1270, the water management consists, step by step, from straightening of 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. Original floodplain alluvial fan Alps Carpathians

7 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 habitats Flood water level Original inundation present Aquifer; Gravel depth 10 - up to 400 m Permeability – 0.01 m/s

8 Main (imperative) objective Flood protection of large areas behind flood protective dikes and reduction of peek flood discharges downstream Flooded area 1965 in Slovakia Protection measures? 10 km

9 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 Gabčíkovo stretch Gabčíkovo stretch Cross section Protected Inundation Main Synergies: Flood protection Navigation Water supply Energy Nature protection - Care of biotops Agriculture Forestry Waterworks Samorin Flood protection dikes

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

12 NATURA 2000 sites (Birds, Habitats) on the Slovak area Lesson: Most of heavy modified and artificial water bodies and attached areas are protected Excellent wintering and breading conditions for waterfowl

13 Joint Monitoring – Ground Water Regime long-term ground water level decrease Komarno Sap Bratislava result

14 Example of previous long term Ground Water Level Decrease Cunovo reservoir Bratislava Sap Komarno

15 Increase of ground water level after filling the through-flowing reservoir with water Cunovo reservoir Bratislava Sap Komarno

16 Ground Water Level Contour Lines (2000 m 3 /s) change of flow direction Cunovo reservoir Sap Komarno Rusovce

17 Joint Monitoring – Ground Water Quality result > change of chemical composition Joint Monitoring – Ground Water Quality result > change of chemical composition Rusovce 18 mg/l 30 mg/l

18 Example of Culmination of water levels and flow rates during the flood event in AUGUST 2002 Station, River km Time of Culmination (day, hour) Max. Water level H max (cm) Max. Flow Q max (m 3 s -1 ) Difference from previous station (m 3 s -1 ) Bratislava- Devín, 1879, , Bratislava, 1868, , Medveďov, 1806, , Gabčíkovo 1070 Komárno, 1767, , Budapest X Difference Devín - Budapest X X – flow rate of the Danube confluents between Devin and Budapest, approximately 300 – 400 m 3 /s. Peak flow in Budapest was lower by app m 3 /s than the peak flow in Bratislava

19 Peek Flood Water Storage inside of aquifer was estimated to 580 m 3 /s in this area Increase of GW level 48 hours after flood culmination in August 2002 Legend GWL difference in m

21 New water stream new eupotamal Interconnection of main arms, conditions for preservation various water formations (river arms of all types, lakes, inundation pools, water holes etc). All between the Water supply from by-pass protective canal and/or from the Old dikes. Danube. Crossing the old river bed by the new water stream at several places. Various hydrological conditions. Revival of the arm mouths, interconnection of arms, etc. Proposal example

22 Objectives – Benefits – Impacts Community – Nature resources ? Integration Synergy ? 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 Policy TTT Project

23 Slovak Republic is offering, as an input into the Danube Region the TTT Project, which will contribute to following objectives of the European Union The TTT project: Creates conditions for all kinds of connectivity, lies in the middle of the Danube Region, and almost in the middle of the EU Creates 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 territory Expects to improve navigation in the Danube in the section Hainburg - Bratislava, hydraulically connecting the Danube Navigation Project East of Vienna with the Hydropower plant Gabcikovo Allows the use of the Danube hydro-potential, approximately 600 GWh per year. Allows protection of the groundwater quality issues at Bratislava.

24 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 section Preserves 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.

25 The TTT project: Strongly supports the economy, trade, and jobs Strongly supports the infrastructure of the territory and small SME projects, including housing Strongly supports the knowledge society, knowledge-based organizations, educations, etc. Supports multi cultural development Creates opportunities to construct reverse pumping storage power station to support storage of wind and solar energy In 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.

26 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.
