Resumo
Reference flows are important variables for assessing water availability in Brazil, as well as
in rural communities in the state of Goiás (Brazil). However, as there is a lack of flowrate data and
measurement points, regionalization methods have been used for forecasting the minimum reference
flow (Qref) allowed for maintaining water uses. The present research covered 92 hydrographic
basins within 46 selected rural communities in the state of Goiás, and 21 basins were selected for
carrying out on-site flow measurements, as well as for Qref estimation following three regionalization
methodologies. Results show a large variation between the values measured and estimated by the
three methodologies, but the statistical analysis found regression equations of one of the methods
more suitable for application in rural hydrograph basins of Goiás.
