Cumulative infiltration curves measured in two-layer columns with wettable soils [Dataset]

[ENG] The dataset is structured in a single Excel file with three sheets, each containing raw data of cumulative infiltration curves followed by gravity drainage. In each sheet, the first row labels the different infiltration curves. The infiltration curves are defined by pairs of columns, where the first column denotes time (in seconds) and the second column of each pair corresponds to the cumulative infiltration data (in centimeters). Each pair of columns represents a different material, distinguished by color-coded headings for clarity. The first sheet, labelled Synthetic Infiltration Curves, contains the infiltration curves followed by gravity drainage simulated with HYDRUS-1D on 5 cm high columns with different materials. These include homogeneous columns of sandy loam (SL) and loam (L) as well as columns with different soil configurations and geometries. For example, 1 cm SL-4 cm Si means a 1 cm layer of sandy loam over a 4 cm layer of silt (Si). The second sheet, entitled Laboratory Infiltration Curves, contains two cumulative infiltration curves measured in laboratory in two different columns of 5 cm high. The columns consisted of a 2.5 cm layer of sand on top of a 2.5 cm of sieved loam soil, and the reverse configuration. The third sheet, Undistub. cores inf. curves, shows the cumulative infiltration curves measured in undisturbed soil cores collected from forest soils coming from three different municipalities of Huesca-Spain.
