Level of commitment, water availability and main consumptive uses in the Guamá Hydrographic Sub-Region, Northeast Pará
The study presents an overview of the level of commitment and water availability of the Hydrographic Sub-Region (SRH) Guamá, located in the Hydrographic Region of the Atlantic Coast-Northeast of the State of Pará. The grants issued by the Pará State Department of Environment and Sustainability (SEMAS) were analyzed and, considering the data from the river gauge stations available at the site, a water balance of the region and the level of commitment of the respective sub-basins that compose it were obtained. The results revealed that, from a global perspective, the Guamá SRH fits into a condition of water comfort, according to the criteria of the European Environment Agency and the United Nations, since the total flow rate granted for the various water uses is equivalent to 1.57% of the reference flow rate, considering 70% of the Q95%, according to CERH Resolution No. 10/2010. However, when analyzed in detail, three sub-basins of the SRH Guamá showed a significant degree of water impairment, classified as worrying and critical, indicating that the demand for water use is reaching levels higher than the region can support, thus requiring appropriate management measures to ensure the sustainable use of this resource. Therefore, this study provides subsidies for the management of water resources in a watershed in the state of Pará, since the scenario of water availability of the SRH Guamá, reflects the reality, in terms of data and economic and environmental characteristics, of the various watersheds in the northern region of Brazil.
