Development of flood protection centre of Szanazug and rehabilitation of the penstock and hydro-mechanical equipment in Tulca

LP: The project aims are to ensure  prompt actions related to emergency situations and disaster management in Crisul Repede si Crisul Negru cross-border basin, sustainable development and, as a secondary role, provide the necessary water in dry periods. The Sewer Channel, with a length of 61 km between Crisul Repede at north, downstream of Oradea, Crisul Negru at south, upstream of Zerind, with the role of capture and lead debit valleys and interior gullies of Crisul Negru, for defending the flood zone plain of the two Crisuri it has at the upstream end of the outlet, the Tărian, and at the downstream end of a drainage weir at canton Mociar. At the upstream end, the Tărian Canton, the sewer is dammed with a length of approx. 1.00 km, with a width of 40.0 m dams. The hydrotechnics is composed of: access channel, reservoir dam, energy absorber,concrete prism, raw stone prism. Dam weir Tulca from the sewer channel, is located at km 20 + 805-50 m downstream of the discharge Culiser and is built of reinforced concrete, equipped with four openings, bounded by the pile of concrete the size of 4.00 x 1.00 m and height 6.40 m, wherein   two metal elements of 2.2 x 2.4 m each overlaps and handles itself manually. The concrete structure of the node presents damaged areas where visible surfaces of the concrete indicates a critical condition, patches here and there of bare rusting and fittings. To rehabilitate the construction it is needed some repairs. The existing concrete prism, has been deteriorated, needing some repairs. Also the raw stone prism has been deteriorated. In the order of the damaged concrete of the dam the repairs will be made through the following solutions:                                                                                  -        Rehabilitation of the existing concrete structure                                               -        Reinforced concrete structure new grid                                                -        Replacement of hydromechanical equipment and procuring new ones          -        Electrical connection      As a result of the project,  for  56280 inhabitants and other entities who are living or situated between Crisul Repede  and Crisul Negru's  flood basin  the flood control will be increased. PP: The border cuts the catchment area of Körös rivers into two. As a result of this, the Hungarian side has the lower segments of the riverbank, while medium and upper riverbank segments and their catchment areas, which are important from the point of view of discharge changes, can be found on the Romanian side. Interventions influencing natural water flow carried out in any parts of the catchment area have an effect more or less on the entire catchment area. The flood and internal water safety of the Körös Rivers depends on the interventions carried out for flood and internal water prevention on the Romanian side, because the development of floods is mainly influenced by interventions carried out in the mountainous catchment areas of the Körös Rivers. The water conservancy relations between the Hungarian and Romanian parts of the Körös region regulates the Hungarian Romanian Water Conservancy Agreement The Agreement of 15 September 2003, which already takes the Water Framework Directive for its base, was signed by the Government of the Republic of Hungary and the Government of Romania with the intention to develop their co-operation in favor of the preservation and sustainable use of rivers constituting or crossing the border and other waters divided by it and also in favor of the protection of water ecosystems. Their most important objectives are: achievement of good water conditions, prevention of water degradation, pollution control, prevention, reduction and control of harmful, cross-border effects (floods, events caused by drought and extraordinary pollutions), development of systems controlling and evaluating water conditions, assurance of the sustainable use of water resources, facilitation of joint research and technological development actions. Regulation of Flood Control which is an annex of the Agreement regulates measures and tasks to be carried out during flood and ice damage prevention, before high waters, during and after their subsidence and in the period of freezing and its breaking up, in order for these to be carried out harmonized and efficient on the river segments mentioned by the annex of the Agreement. The stipulations of the Regulation of Flood Control are applied by the appointed water conservancy bodies of the countries. In the case of Körös rivers, this is KÖVIZIG and the ABAC. Flood Protection Centres have important roles in cases of extraordinary events (floods, extreme pollutions, special weather conditions), when preventive and protective measures must be taken, and in occurrences when immediate intervention is needed. Reports about negative developments occurring on defences are sent here and these data will be then forwarded by the local staff to the operative centre. Workers and forces from afar are accommodated at these centres. On-site protection work is coordinated, controlled and managed from these centres and all resources necessary to the prevention of hazards (labour, raw materials, machinery and equipment) are also sent here. The flood protection centre could use by Körös Valley District Water Directorate’s employee and partner water directorate’s employee as well as Romanian party flood experts, whose make flood protection missions in flood control time. The flood protection centre hosts for professional and commission meetings without the flood prevention period. Because of these KÖVIZIG wants to implement an overall reconstruction and a development in the building of Flood Protection Centre of Szanazug. Objectives of development are the follows:      - the efficiency of common flood prevention increasing      - increasing of flood protection safety of protected flood basins      - modernization and development of prevention infrastructure institutions As a result of development effect all in all 91.590 inhabitant who are living in nr. 2. 93. and 2. 94. Gyula’s and Békés’s flood basin, the flood control of the inhabitant will increase. The renewed Flood Protection Centre of Szanazug not only develop the KÖVIZIG’s flood control infrastructure but contribute to the defensive Romanian and Hungarian parties for the coordinated activities that create a new base and new a platform because they are situated on border and area of common interest so increasing the efficiency of prevention occasion  of disaster situations.

Achieved: 1) The rehabilitation of the existing dam in Tulca was made, and it ensure the protection of the inhabitants between Crisul Repede and Crisul Negru, and also of the socio-economic objectives in affected areas. 2) The renewed Flood Protection Centre of Szanazug developed by KÖVIZIG’s flood control infrastructure contributes to the defense against disasters in the cross-border area, increasing the efficiency of disaster prevention activities. 3) The project ensures prompt actions related to emergency situations and disaster management in Crisul Repede and Crisul Negru cross-border basin, sustainable development, and, as a secondary role, provide the necessary water in dry periods. Finalized: 1) Office equipment have been purchased, in case of both partners, to be used by their employes as well as by the flood experts involved in flood protection missions, in flood control time. 2) Szanazug Flood Protection Centre rehabilitated. 3)The two floating platforms along the bank of the river renovated. 4) Tulca dam existing construction rehabilitated. The existing hydro mechanical equipment for closing and opening the dam was replaced;

The present project answers directly to the current situation, with proposed measures for future flood prevention and reduction of the effects of floods, the general objective of the project being the reduction of flood risks with effects on population in the most vulnerable areas, accordingly to the programme priority specific objective, namely removing from the flood effects a number of 147870 inhabitants.The implementation of the present project follows closely the Flood Risk Management National Strategy in both countries, the project including proposed measures for preventing future floods and risks associated with these, development of an effective operational management during floods, as well as mitigation of flooding effects such as pollutions, damages, loss of human lives etc. The destructive intensity of the flood events produced mostly in the last decade highlighted the need for an integrated and sustainable approach to flood risk management to reduce the severity of future flood damages. Floods during 2005 and 2006 when most of the rivers in Romania reached historical limits, leading to effects of catastrophic nature (over 1.5 million people were affected, the extreme flood events led to 93 people being killed, and severe infrastructure damage). A brief statistics shows the vast negative impacts of floods in the last years, and the accentuated need for flood prevention and flood effects mitigation in Romania and Hungary also, recognized both by the EU through the Water Framework Directive, Strategic guidelines and regulations, as well as by the Romanian Government who has established and implemented the Flood Risk Management National Strategy in 2010 (through GD 846/2010). Through rehabilitation on hydro node Tulca and flood defense center Szanazug, the control and coordination of the exploitation of hydro technical constructions by CWBA and KOVIZIG will be assure a rapid intervention in case of floods and pollution associated with floods.
