Abstract

Water resources and aquatic ecosystems are facing significant threats due to unsustainable water management practices. To address this challenge in Romania, a sustainable approach to water management is necessary, re-thinking ecological flow. This article proposes a re-thinking of the current approach to ecological flow in Romania by advocating for a more holistic and integrated approach considering environmental factors. The objective of the article was to present a methodology for the establishment of ecological flow that took into account the natural variability of flows. Four ecological flow values related to flood, high-water, medium-water, and low-water hydrological regimes were defined. To establish them, the duration curve of average daily flows was used in conjunction with hydromorphological and biological indicators. The proposed methodology was applied and compared to the existing methodology for the Uz river developed with hydropower use. The methodology represents a transition from the anthropocentric perspective to the sustainability perspective. The proposed methodology is easy to apply, with rigorously defined hydrological, hydraulic, and biological criteria. This research was conducted within the Hydrotechnical Faculty to refine the Romanian legislation regarding the improvement of the ecological status of all rivers.
