Nevertheless, the SEM approximates the true hydraulic functions of most soils very well, with mean deviations below 0.1% volumetric water content and below 0.1 for log10 of hydraulic conductivity.
Pore morphology and other hydraulic functions of soil, for example, mean connection surface of pores, hydraulic conductivity, and the efficiency of water conducting macropores also support the X-ray CT findings.
DREC, developed by the hydraulic functions of a drainage system, can be defined as a groundwater reservoir, which is limited by soil surface and which occupies an intermediate position in the water table.
The approaches were: a modification of the hydraulic conductivity function (Hydraulic function), the lumping of all macropores into one single straight macropore (Lumping), the use of an exchange factor between microporosities and macroporosities that occupy the same area (Dual porosity), and a detailed description of each macropore (Full description, base case).
The analytical description of a curve passing experimental data sets of the soil hydraulic function is typical for the empirical equation characterized by fitting parameters only.
The wells have no hydraulic function; they helped in the digging of the foggara and serve presently as air vents (chimneys) and as observation manholes for the tunnel.
Hydraulic characteristics of the analysis mechanism to obtain the parameters of the hydraulic output torque T HC, hydraulic control weight W HC, and mechanical hydraulic function area S AHC are shown in formula (6).
Shortcomings associated with the use of the SWCC to estimate the hydraulic conductivity function of partially frozen soils are discussed.
For example the paper shows that the hydraulic conductivity function of the geotextile must be reduced by up to two orders of magnitude to give acceptable agreement.
The hydraulic barrier function of the underground continuous wall is simulated at four different depths including primary design depth, increasing 3 m, 4 m and 6 m.
