Analysis of Performance of One-dimensional Soil Water Infiltration Models

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
