Resumo: |
The development of this research aimed to evaluate the behavior of the groundwater in the catchment area of the Botafogo stream in Goiânia / Goiás, through the monitoring and mathematical modeling of the free aquifer, using data from the level of the sheet, measured in the period of drought and rain, between May / 2016 and June / 2017. Monitoring was performed by measuring the groundwater level with the Water Tape electric meter in monitoring wells distributed throughout the basin. These piezometric level data helped to obtain the observed hydraulic loads and constituted input data for interpolation of the hydraulic load that entered as an initial condition in the modeling of the water table of the study área. Comparing the results of the dry period contemplated in 2016 and 2017 by this study, we noticed a greater fluctuation of groundwater level. The load contour condition defined in the calibration of the hydraulic conductivity of the Botafogo basin was of local flow, making possible the estimation of the recharge and the calculation of the outflow in the basin in permanent regime. In the transient flow regime, it was observed that, with the increase of hydraulic conductivity, the level of the water table rose, in the zone downstream of the Botafogo basin, but remained continuous over time, in terms of the highest value calibrated for the parameter storage (0.48 m³/day). Therefore, the fluctuation of the groundwater level in the catchment area of the Botafogo basin can be reflected both in the recharge caused by the precipitation and in the variation of the hydraulic load (the increase of which tends to degrade the water table). |
