Resumo: This study aimed to improve our understanding of the ecohydrological characteristics of environmental and modified flows in Portuguese rivers considered Heavily Modified Water Bodies (HMWB), using the Indicators of Hydrologic Alteration (IAH) method. For a given set of "heavily modified river sections", this study did the characterization and analysis of present flow regimes observed, natural flow regimes, and ecological flow requirements simulated by the method of INAG, DSP (2002). Based on Indicators of Hydrologic Change, the determination of the deviations from natural regimes was performed for the present hydrological regimes: both modified and ecological. The analysis of indicators of hydrologic alteration, based on ecohydrologic assumptions that guide the definition of environmental flow regimes, allowed to develop proposals for environment mitigation, whose effectiveness should be evaluated in the context of monitoring the ecological quality of HMWB sections in order to achieve the environmental objectives set out in national and European legislation on water resources the Water Frame Directive WFD (Directive 2000/60/EC) transposed to the Portuguese legislation by the Water Law - Law n.º 58/2005, 29 December 2005
