The first three points of the graph are lower because air has remained trapped in the sample. The hydraulic conductivity becomes almost constant after about twenty minutes. The average hydraulic conductivity does not need to be converted to the standard temperature because we worked at the standard temperature. The average hydraulic conductivity is 2.8 ∙ 10-5. According to the saturated hydraulic conductivity classes, modified according to Kutilek and Nielsen (1994) it is typically a clayey sand. Soil classified according to the permeability classes proposed by O'Neal (1949) indicates that the class is moderately rapid. Water will flow rapidly through the soil, so when you apply irrigation or drainage to this soil, it will probably drain quickly but to be sure you need to calculate the infiltration rate which depends on the difference in hydraulic head. There are two important properties that determine hydraulic conductivity: the geometry of the pore system and the intrinsic properties. The geometry of the land exists from the structure and the st...
