The knowledge about water availability is a basic information for making a decision in the granting process. So, the knowledge on the discharge along the hydrographic network requires the use of discharge regionalization techniques. However, the application of the regionalization models constitutes a difficulty to the quantification of water availability, since their application requires the knowledge of the basin physical information. The development of techniques for the generation of digital elevation models propitiated the use of the Geographical Information Systems for automatic obtainment of the basin physical characteristics, as providing more quickness and higher reliability to the application of the regionalization models. So, this work was carried out to develop an integrated system that would make possible the optimization of the water resource management process, as aiming at the best use of the water and the reduction of the conflicts among users, as well as to accomplish a case-study for the river Paracatu basin, by using the developed system. The programming tool Borland Delphi 7.0 was used to develop the software, whereas the routines linked to the Geographical Information System were implemented, by using the component ESRI MapObjects 2.3. Those routines were elaborated in order to allow for the localization of an interesting section along the hydrography of the basin and from which to obtain the data relative to the interesting section for estimating the minimum and average discharges by different regionalization methods as follows: traditional; based on the proportionality of specific discharges; and based on the conservation of masses/discharge continuities. After estimating the discharges, the software proceeds to the calculation of the water availability in the interesting section, taking into account the maximum discharge possible to be granted and both state and federal grantings emitted upstream, so taking into account the main elements in a granting process. The developed software was called as SINGERH, and was applied to the basin of the Paracatu river in order to verify its functionalities and potentialities. The SINGERH turned possible the obtainment of the minimum and average discharges along the hydrography of the basin, besides to supplying subsidies for making decision in the granting process when estimating the water availability in any section of the hydrography. The case-study turned possible to verify that the grantings emitted in the basin of the Entre Ribeiros creek rather overcome the maximum grantable limit in Minas Gerais State. Thus, SINGERH constitutes a tool for the integrated management of the water resources, as allowing for a shared and efficient use of the water, therefore minimizing the conflicts among its users.
