ATTEMPT AT IMPLEMENTING THE 2015 “ECOLOGICAL FLOW ASSESSMENT METHOD FOR POLAND” IN THE WIEPRZA RIVER CATCHMENT

Keywords: ecological flow, water requirements of aquatic and water dependent ecosystems, hydrological regime, water management, water balance
Abstract:

Safeguarding hydrological regimes appropriate for aquatic and water dependent ecosystems is necessary in order to achieve or maintain good ecological status (or good ecological potential) of water bodies, being an important task of sustainable water management. Water requirements of ecosystems are mainly represented by minimum hydrobiological or ecological flows, which constitute a limitation to the use of water resources. The main objective of this paper is a comparison, in terms of economic effects of application, of the new ecological flow assessment method with the currently operational hydro-biological flows (RWMB Szczecin method, 2014), and the simplified hydro-biological flow method by Kostrzewa (1977). Another issue is to evaluate whether the ecological flow method is useful and applicable to water balance planning analysis. Computer simulation approach has been used. Calculated hydro-biological and ecological flow volumes were presented along the Wieprza River longitudinal profile and in the selected cross-sections. The time reliability of maintaining the ecological flows as well as changes in volume of available water resources have been used to evaluate economic effects of the new method implementation. It has been proven that the application of ecological flow requirements causes a decrease in the available water resources for both existing and potential water users. Based on the results, selected issues have been discussed, related to the methodology of ecological flow determination, especially gaps and inconsistencies calling for additional assumptions.
