Abstract

In the present work three discharge regionalization were analyzed to estimate minimum discharge with a 7-day duration and a 10-year return period (Q7,10) for different sections of the Paracatu river basin. The regionalization methods used were: traditional; based on the proportionality of specific flows; and based on the conservation of mass. The Integrated System to the Water Resources Management (SINGERH) was carred out to estimated the Q7,10 to different sections. Was evidenced, in the obtained results, in some sections, expressive differences in the Q7,10 values for the three regionalization methods studied. The method based on the conservation of mass was the only that guaranteed the continuity of the flows in the whole area in study. The analysis allowed to verify a larger care in the choice of the regionalization method, because it can hamper the process of decision in the water resource management.
