BAUTISTA-DE-LOS-SANTOS, Quyen Melina. Determination of Environmental Flows in the Yuna River Basin, Dominican Republic. Tecnol. cienc. agua [online]. 2014, vol.5, n.3, pp.33-40. ISSN 2007-2422.

Environmental flows were estimated using a range of variability analysis (RVA) and hydrological alterations indicators (HAI) at three points in the Yuna River basin (Hatillo, Rincón and Blanco reservoirs), located in the Dominican Republic. The series of daily flows for each study site were obtained using a combination of synthetically generated monthly flows and disaggregated daily flows. The 33 parameters calculated for each point were used to determine environmental flow regimes, demonstrating that the application of the method is feasible at the local level, in spite of the difficulties found to survey and process the data.
