The study of water infiltration processes into the soil helps to understand hydrological processes, soil degradation and solutes transport, with significant support to minimize runoff processes. The aim of this study was to evaluate the infiltration behaviour through Kostiakov, Kostiakov-Lewis and Philip models. This research was carried out at the Puerto López municipality (Meta-Colombia). The methodology included the implementation of 64 infiltration tests, using double ring infiltrometer, located in a rectangular grid sampling of 52m by 45m. At each grid point soil samples were taken at 10cm depth, to determine texture, bulk density and volumetric moisture. With the experimental infiltration curves adjustments were made to the empirical models for each point. For data analysis descriptive statistics were implemented in order to understand the behaviour and dispersion of soil properties. Correlations between soil properties and parameters of the estimated models were also established. The experimental data were better fit the Kostiakov-Lewis model, following the model of Kostiakov, with an R 2 of 0.99 and 0.98, respectively. The property of higher incidence over the infiltration was the bulk density, showing an inverse correlation with most of the parameters. The infiltration variability indicates the desirability of identifying management zones, to avoid a deficit or excess water, which can carry the crop to water stress or contribute to runoff processes.

“…The parameters "a" and "b" are site-specific since they depend on texture, structure, vegetative cover, infiltrometer type, moisture condition, rainfall intensity, permeability, soil surface conditions and properties (Al-Azawi, 1985;Moroke et al, 2009;Adindu et al, 2014;Smith, 1972;Adeoye, 2010 Dixon, 1976;Swartzendruber and Huberly, 1958;Childs and Bybordi, 1969;Carvalho et al, 1999;Berndtsson and Larson, 1987;Kelishadi et al, 2014;Dagadu and Nimbalkar, 2012). Giffobd, (1978) concluded, that it appeared that Kostiakov equation coefficients were related more to vegetation factors than to soil factors based on an analysis of data.…”

This report consisted of studying the effects caused by the soil physical characteristic, in the presence of wetness variations and structures-texture fluctuations, to the Kostiakov constants. The objectives were to investigate the effects of wetness, soil depth, and compaction on the Kostiakov constants “a”, and “b”. The experimental unit consisted of nine polyvinyl cylinders. Statistical analysis under a randomized block design with three replications and three factors: wetness with five levels, soil depth (0-15, 15-30 and 45-60) and compaction with three levels (0, 13 and 26 blows). The relation between the instantaneous infiltration versus compaction and bulk density were inversely proportional. The parameter “a” influenced infiltration more than “b”. Soil texture and structure influenced “b” more than wetness. Wetness influenced “a” more than compaction and soil depth. Kostiakov parameters exposed physical relations to soil texture and structure.
