Abstract

THE IDEA OF RELOCATION OF DISPOSABLE RESOURCES IN WATER MANAGEMENT AREAS WITH REGARD TO GROUNDWATER-DEPENDENT ECOSYSTEMS – THE WISŁOKA CATCHMENT CASE STUDY

Abstract. In 2013–2019, PGI-NRI carries out a project documenting groundwater disposable resources for conducting water-economic balances. Among the balance areas documented directly by the PGI-NRI is the Wisłoka catchment and part of the Wielopolka catchment covering the Flysch Carpathians. The geological and structural structure of the Wisłoka catchment brings about the diversification of hydrogeological conditions, and the largest amounts of groundwater are found in the Quaternary formations of river valleys. Disposable resources were located within them due to the thick (considering the Carpathian conditions) packages of well-permeable sediments. In a situation when part of disposable resources (calculated by the hydrological method) could not be used in a given drainage basin, due to exceeded permissible groundwater table reduction in protected areas, it was decided to transfer unused reserves to balance areas of midwives in lower sections of rivers in a manner that does not interfere with the protection of their minimum acceptable flows.
