description The studied area, APA Lagoa Santa Karst and its surroundings, is located 35 km north from Belo Horizonte and it covers around 505 km². The region has been a target to many enterprises that demand an increase on water request. Having as a scenario this growth and the fragility of the Karst system, it becomes necessary to know the hydrological system, as well as to understand the hydric balance. Geologically, the area is represented by metacalcarium and neoproterozoic metapelitic rocks from The Bambuí Group, with rich density of features of karstic dissolution that make the recharge and the fast conduction of the flows water. The drainage of the region is affluent by the left bank of Das Velhas river that functions as its base level. The objective of this project was to perform the water balance, with emphasis on the aquifer recharge, considering the complex underground drainage network with inputs and outputs of the system. Available information about hydric connections have helped on the adopted circulation model used to equate hydric balance. 6 fluviometric stations were installed in 6 basins, having monitored the hydrological year of 2016/2017, whose data was used to calculate its recharge using the methodology of Rutledge and Daniel (1994). The average flow of the basin in 91% of the total confirms the importance of underground water to the hydrological system and the recharge of 12% of the annual precipitation (1010 mm) can be adopted as minimum value, once there are other hydric outputs that are not analysed in this work.

A região tem sido alvo de vários empreendimentos que prever um aumento pela demanda de água, diante deste crescimento e da fragilidade do sistema carste é imprescindível o conhecimento do sistema hidrológico, tal como a compreensão balanço hídrico. Geologicamente, a região é representada por metacalcárias e metapelíticas neoproterozoicas do Grupo Bambuí, com rica densidade de feições de dissolução cársticas que favorecem a recarga e a condução rápida da água. As drenagens da região são afluentes pela margem esquerda do rio das Velhas que funciona como nível de base. O objetivo do trabalho foi realizar o balanço hídrico, com ênfase na recarga aquífera, atentando para a complexa rede de drenagem subterrânea com entradas e saídas do sistema. Informações disponíveis sobre conexões hídricas auxiliaram no modelo de circulação adotado para equacionamento do balanço hídrico. Foram instaladas 6 estações fluviométricas em 6 bacias, monitoradas no ano hidrológico 2016/2017, cujos dados foram empregados no cálculo da recarga aplicando a metodologia de Rutledge e Daniel (1994). O escoamento de base médio das bacias de 91% do total confirma a importância da água subterrânea para o sistema hidrológico e a recarga de 12% da precipitação anual (1010 mm) pode ser adotada como valor mínimo por haver ainda outras saídas hídricas não contempladas no trabalho.ABAS - Associação Brasileira de Águas Subterrâneas2019-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://aguassubterraneas.abas.org/asubterraneas/article/view/2925210.14295/ras.v33i2.29252Águas Subterrâneas; v. 33 n. 2 (2019): REVISTA ÁGUAS SUBTERRÂNEAS; 119-1332179-97840101-7004reponame:Águas Subterrâneas (São Paulo.
