“…This agrees with the results of Machiwal et al (2006). Soils in the field are more heterogeneous than laboratory soil cores and this is a possible reason for the differences.…”

“…However, complicated factors that influence the final infiltration rate are a major reason for the different applicability of the models. Machiwal et al (2006) observed infiltration was well described by the Philip's model in wasteland in Kharagpur, India. Navar and Synnott (2000) evaluated the infiltration rates of soils under four land uses in north-eastern Mexico.…”

“…This model takes the form of Equation [1] (Gil, 2002): ) and describes the water absorption by the soil as a result of the gradient of the matrix potential and Ks is the saturated hydraulic conductivity (cm h -1 ). Some authors define the constant Ks as an adjustment parameter (Lima and Silans, 1999) or a factor (Machiwal et al, 2006), specifying it as a transitive constant that depends on the initial water content and the soil conditions. Through Equations [1] and [2] it is shown that when soil moisture is low, the initial rate of infiltration is high, due to the sorptivity, but with time the infiltration rate reaches a constant value, which is defined as the Bi and is similar to the saturated hydraulic conductivity (Gil, 2002).…”

“…he need to satisfy the present and growing demand for food stimulates the development of research related to the management and use of water, an essential factor for increasing agricultural production, since an efficient application of water fundamentally depends on the infiltration capacity of the soil (Machiwal et al, 2006). At the same time, characterizing the infiltration process constitutes one of the basic parameters of the adequate design and management of the risk systems in agricultural production.…”
