The aim of the project is to support the protection of nature and biodiversity in the Dyje River basin through effective cross-border exchange of data and knowledge. The project strengthens cooperation between the Czech Republic and Austria. The Czech-Austrian Commission for Trans-boundary Waters will gain science-based tools for ecological and coordinated water management, including a joint database, an emission model for risk analysis (EQS), a scenario analysis tool, and a joint strategy for improved water pollution control.
