Abstract

The increasing urbanization and impermeabilization of the soil aggravates several negative effects in the hydrological cycle of the water, directly impacting the recharge of the groundwater and groundwater. In a central and relevant region of the city of Recife, the objective of this study was to analyze the performance of six numerical models of unidimensional water infiltration in the soil: Kostiakov, Horton, Philip, Kostiakov-Lewis, SCS and Swartzendruber, comparing their models with infiltration tests performed using the infiltrator. For performance analysis, the following statistical parameters were used: coefficient of determination, ratio of deviations, modeling efficiency and mean square error. All of them proved to be quite effective in carrying out the proposal, especially Kostiakov-Lewis, who presented excellent performance in all the statistical indicators
