“…In the mid-1990s, a seasonally constant minimum flow downstream from the Stratos dam was defined through the statistical analysis of the average monthly naturalized discharges of the driest month (August) (Hydroexygiantiki, 1995;Efstratiadis et al, 2014), and in 1996 a constant value (1 m 3 •s -1 ) was assumed downstream from the Evinos dam according to the water resources management plan (Zarris, 2010;Ministry of Environment, 1996). For large dams, some studies related to E-Flows have been developed, for example for the Gadouras dam for which E-Flows have been defined and applied, but neither an overall plan nor a guideline for practical applications have been defined (Stoumboudi et al, 2019). The National Law 3199/2003 is the first attempt to transpose the WFD into Greek legislation (Farmaki and Tranoulidis, 2020).…”
