Abstract: Nowadays, the environmental flow (e-flow) is globally recognised as an essential component of the sustainable water resources management. Therefore, defining flow requirements is an important step forward, especially in transboundary regions where different water management practices exist. This study aims to propose a GIS-based methodological framework for regional-scale environmental flow modelling and hydrological regime classifications to further define environmental flow requirements in the Bulgarian-Greek Rhodope Mountain Range. The methodology incorporates GIS-based interpolation techniques and environmental flow magnitude modelling in order to identify the quality of ecosystems, based on indicative environmental flow values at any point in the region. Suitability model was generated to classify the preferential locations for aquatic and riparian communities into five ecological management classes (EMC). Furthermore, cluster analysis was applied to 198 catchments in order to distinguish five different zones of watersheds with homogeneous hydrological and morphological characteristics.
