The value of the probably granted discharge is affected by the method used for its obtainment, and several methodologies are available to this purpose. The Integrated System for Water Resources Management (SINGERH) allows to obtaining water availability for any interesting section along the basin hydrographic net, as well as to quantify the impact from the granting of a new water right in this availability. So, it was used in this study in order to verify the impact of either grant criteria and the discharge regionalization methods upon the estimate of water availability in the basin of the Entre Rios creek. The data basis needed to the application of SINGERH was initially prepared. It consisted of digital elevation model of the minimum and medium discharges, regionalization equations of both the traditional method and that based on mass conservation and the cadastre of the basin water users. The results showed the impossibility of new grants for water using right until the end of the period under analysis. The accomplished simulations allowed to evaluate the way how variable water availability affects the water using right process, besides providing subsidies to the analysis of the different criteria adopted for the distribution of discharges to be granted.
