problem definition
Problem definition

The Bodrog river sub-basin, - part of Tisza catchment area –has been affected by several major flood events in the past decade in all countries which are sharing this territory (Slovakia, Hungary and Ukraine).

Each country within the Tisza catchment has developed its own mitigation strategy and plan focused on flood management and flood prevention.

However, there is a lack of harmonization of national strategies within Bodrog river basin and common understanding of proposed measures and activities on the cross-border scale and unsatisfactory involvement of local stakeholders (municipalities as well as NGOs).

project objectives
Project objectives

Main project objective→ to mitigate consequences of floods through achieving consistent and holistic management of flood risk in Bodrog river basin countries:

  • creating partnerships between national and local levels through the development of common “Strategy for mitigation of floods for Bodrog river basin countries”,
  • implementation of sustainable solutions for flood preventionthrough pilot investments.

Project activities should consider - where possible - the maintenance and/or restoration of floodplains by creating “space” for water during flood events.

The involvement of municipalities, NGOs, farmers, spatial and urban planning authorities is crucial. Therefore project activities will focus on establishment of the close cooperation with these stakeholders.

outputs
Outputs
  • Formulation of the “Strategy for mitigation of floods for Bodrog River Basin countries”.
  • Improving the conditions of floodplains and wetlands affected by current land uses and environmentally inappropriate flood protection measures.
  • Dissemination of project results to achieve replication on national levels and to other basins.

United NationsDevelopmentProgramme Global EnvironmentFacility (UNDP GEF)Supervisory body: International Committee forthe Protection of theDanube River(ICPDR) – Tisza GroupTotal budget: 128 000 USDHU budget: 55 000 USD

project area
Total area of the Bodrogriverbasin: 11552 km2

Hungary 54 km2, Slovakia 7 272 km2, Ukraine 4 225,7 km2

River system: created from 4 main rivers - Latorica, Laborec, Uh, and Ondava

HU pilot project:

„Waterretention of the Viss oxbow”

Total length:8,1 km

Total area:48,6 ha

Average width:60 m

Average depth: 1,5 m

Average water stored: 0,7 million m3

The oxbow was created during the river regulation works between 24+300 and 25+600 river kmsin the 1860’s.

Itfills up with fresh water during flood events.

Project area
water supplement of the tokaj bodrogzug lpd
Watersupplement of the Tokaj-Bodrogzug LPD
  • The oxbow area is neighbouring the Tokaj-Bodrogzug Landscape Protection District.
  • For better quality of biotopes in the LPD, there is a need to retain water inthe oxbow after floods.
  • This can be solved by using the Bodrogzug I. channel which is connected to the oxbow through a sluice.
what is in the plan
What is intheplan?
  • to build a new structure at the 0+150 rkm of the oxbow to retain flood water from Bodrog,
  • to rebuild the sluiceat the 2+500 rkm of the oxbow so it would be possible to provide the Landscape Protection District with water through the BodrogzugI. channel.
preliminary measures
Preliminary measures
  • Field survey
  • Meetings with the stakeholders (mayors, farmers, National Park)
  • Geodetic survey
  • Contracting
  • Preparation for the construction (cleaning the area of the structures from bushes)

risks and risk management
Risks and risk management
  • The formal process of issuing the construction permit by the district authority can take months, it can delay the works in a significant rate.
  • During the implementation period flood events can cause difficulties in construction works through higher water levels and delay the finishing of the construction.
risks and risk management1
Risks and risk management
  • From February to June there were several floods on the Bodrog.
  • The project site was inaccessible, the construction couldn’t start.
  • The contract had to be modified, the deadline for the implementation had to be delayed.
finishing of the constructions
Finishing of the constructions
  • The construction was finished on the 27th August.
  • Official delivery procedure on the 6th September.
