In the Entre Ribeiros river basin, a tributary of Paracatu river, water availability has limited the development of irrigated agriculture, resulting in many water conflicts in the region. Since these water conflicts are not adequately quantified, regional differences cannot be evaluated from the spatial variation of water availability and demand. In order to identify the regions where the water use conflicts occur and to provide information for water resources management and planning, this work analyzed the values of the water resources management index (icg) and the water resources planning index (icp) applied in the Entre Ribeiros river basin. The seven-day minimum flow with a 10-year return period (Q7,10), the long duration medium flow (Qmld), the permitted withdrawals (Qout), the digital elevation model and the river basin hydrography were used to calculate the indexes. The analysis of icg and icp values showed that the water uses in the Entre Ribeiros river basin conflict with the current rules, since the permitted withdrawals are higher than those allowed by legislation. Analyzing the icp, it was shown that the evidenced water use conflicts can be minimized by adopting an appropriate water resources management and planning program. Key-words: water conflict, water permit, water availability.
