英文摘要	Localized recharge from dolines is very important, especially in arid and semi-arid regions, where it contributes to the groundwater recharge on karst aquifers. In areas with a shortage of water, these are the geomorphic structures where water runoffs occur and accumulate. The study area is located in sub-basins of the Rio Verde Grande, in Verdelandia and Varzelandia municipalities, and it displays features of the semi-arid climate (average annual regional rainfall of about 790 mm). The area is also characterized by the presence of dolines in the Neoproterozoic pelitic-carbonate rocks of the karst Bambui Group. To understand the process of such a recharge and quantify it within the study area, automated identification in ArcGIS was applied in order to select two dolines. Also, the following methodological procedures were adopted: soil texture characterization; soil infiltration tests using Guelph and concentric double-ring infiltrometers; permeability tests; automated monitoring of rainfall and groundwater level; water balance estimated with the decendial water balance and water level variation methods. The results yielded local recharge values ranging from 57.7 to 122.2 mm/year (7.8-13.3% of the rainfall).
