Item Disponibilidade hídrica superficial e subterrânea em assentamentos em Goiás(Universidade Federal de Goiás, 2021-03-31) Costa, Isabella Almeida; Formiga, Klebber Teodomiro Martins; http://lattes.cnpq.br/0787413754235970; Scalize, Paulo Sérgio; http://lattes.cnpq.br/0957896448117207; Scalize, Paulo Sérgio; Ferreira, Nilson Clementino; Basso, Raviel Eurico; Formiga, Klebber Teodomiro MartinsDue to the numerous cases of population supply problems due to low water availability, this subject has become one of the references for the management of water. The lack of studies directed at settlement communities makes this management difficult and the reality of the families is unknown. In order to determine the consumption and availability of surface and underground water and the respective specific flow rates in settlements in the state of Goiás, settled communities from the Regional Superintendence 04 of the National Institute for Colonization and Agrarian Reform (INCRA) were selected. The aquifers and study basins were identified according to the location of 62 communities. Through data analysis and methodological application it was possible to obtain estimates of water availability for each community, using the parameters of reference flow rate in 95% of the time (Q95) and exploitable volumes of groundwater and deep aquifers, thus making it possible to calculate the specific flow rates for each resource analyzed. The demands for consumption and for the development of activities were stipulated in order to establish correlation with the results found. It was observed that with regard to surface resources the demands can be met in 64.52% of the settlements, as for the underground resources this index remained at 100% for deep aquifers and 80% for groundwater aquifers. This demonstrates the importance of knowledge regarding the use of resources for the supply of each family and that allows each of these communities to understand the water situation and promote the management of these water resources.Item Avaliação da disponibilidade hídrica superficial no estado de Goiás(Universidade Federal de Goiás, 2020-03-12) Honório, Michelle da Silva; Formiga, Klebber Teodomiro Martins; http://lattes.cnpq.br/0787413754235970 Nomes dos; Scalize, Paulo Sérgio; http://lattes.cnpq.br/0957896448117207; Scalize, Paulo Sérgio; Bezerra, Nolan Ribeiro; Ferreira, Nilson ClementinoBased on the principle that water resources are limited and vulnerable, associated with the use by a growing population, industrial and agricultural expansion, management in an integrated manner is necessary, with the use of preventing damage and ensuring the use of quality water and quantity for the present and future society. The issuance of grants in the state of Goiás for the use of state-owned waters is under the responsibility of the Secretaria de Estado de Meio Ambiente e Desenvolvimento Sustentável, which describes in the Resolução n° 09, de 04 de maio de 2005 the conditions and criteria for effecting the authorizations. In this process, knowledge of water availability is paramount, but obtaining hydrological information directly is not always possible and, in many situations, tools are needed to assist in obtaining this information, such as flow regionalization. So, this study had as main objective to evaluate water availability in surface catchment basins for public supply in the state of Goiás, through the comparison between the traditional method of flow regionalization and the method used by the water resources management agency in Goiás Of the 195 surface catchment basins analyzed, it was found that 27.7% have flows granted that exceed the flow that can be granted and/or exceed the reference flow present in 95% of the time. It was concluded that these catchment basins for public supply are in critical situations and that the grants, granted in these places, exert an excessive pressure on the springs, since the withdrawal of water is greater than allowed. As much as water availability estimates have been carried out using flow regionalization, these areas can be considered as priorities for the planning and management of water resources and for implementing actions based, for example, on payment for environmental services.
