The aim of the project is to implement interventions that serve to protect environmental values, achieve good ecological, water quality and quantitative status, improve management of karst water, inland and rainwater as water resources and increase the level of protection against water damage. In addition to agricultural areas, inland areas are also exempted from the adverse effects of flood waves from hilly areas. As a result of the development of wetland systems, greater retention of rainwater is achieved, and slowing down the run-off. In addition to ecological aspects, this objective is also served by the close-to-nature organisation of certain sections of the VALW. The Felcsúti reservoir and the Óbarok side reservoir will increase the safety of water supply in the watercourse area over the long term, increase the quantity of fresh water that can be held, and it will be possible to satisfy new irrigation, fish pond and other water requirements, while flood safety is not reduced. With the construction of the Váli reservoir, the risk of water damage in the areas below is reduced by the storage of some 600 thousand m³ of water from the peak of the flood wave. Reservoirs are suitable for the safe transformation of flood waves in such a way that the flood wave entering the reservoir is passed on by the Water Directorate over a longer period of time, but with a smaller peak and more uniform flow. It will be possible to temporarily receive, store and use winter-spring, increasing water flows in the summer seasons. This reduces the negative effects of water surpluses or shortages. The water resources retained in the permanent reservoirs are suitable for providing the ecologically necessary water flows in the sub-water basins and may be used as dilution water in the event of a possible snowfall. In order to maintain the water carrying capacity of the Vali-water and to protect against erosion effects in hilly areas, it is necessary to construct energy-breaking and sediment-catching structures that regulate the drainage water. The rehabilitation of the watercourse contributes to the restoration of the natural nature of the watercourse, to the survival of the areas designated for the protection of protected natural values, habitats and animal species, to the realisation and strengthening of the “green corridor” character of the Váli-water, the environmental status of the river basin is improving, and the eco-tourist attractiveness of the micro-region is increasing. The development, construction and automation of precipitation meters and water level detection stations in the catchment area serves the subsequent operation of the water system at the appropriate level and to better monitor the impact of the more extreme weather. In order to ensure the significant water use of the water system and water supply of wetlands of sufficient quality, water quality monitoring sites are needed at the main plants. After the maintenance roads and lanes are put in good order, maintenance and protection tasks can be carried out more easily. Expected results of the project The technical interventions reduce the likelihood and extent of price and local water damage: — 600.000 m³ of water can be stored in the Váli torrent during large condensations. — Number of settlements protected from the standard flow due to reservoir construction, refurbishment and bed rehabilitation: 7. — Under the influence of reservoir construction, refurbishment and bed rehabilitation, the size of the residential areas protected from the standard water flow is 2.6 km². — The number of permanent residents protected from the standard flow is 5,224. — The length of the main roads protected from the standard flow is 1 km, and the length of roads is 2 km. The implementation of water retention improves water resource management in the water system in both quantitative and qualitative terms. — The excess quantity of water available after the construction or conversion of the reservoirs is 94.000 m³. If the development concept is realised, the established independent monitoring element becomes available on the internet as public data, graphical and geospatial visualisation. In order to achieve the objective of the project, it is necessary to implement 8 main project elements: Structure of beds, Construction of Maintenance paths, Reconstruction of Artifacts, Construction of Artifacts, Construction of Storages, Establishment of Water habitat System, Protection against Erósion, Plant Plantation, Restoration of Coastal Zone, Development of Monitoring System.
