From the sand samples collected from regions in different places in the desert, the frequency of occurrence distribution of the equivalent salt content ESC (mg of salt/gm of sand) could subsequently be built as shown in Fig. 4a. Fig. 4b subsequently shows the probability density distribution of the sand conductivity p(c). In the following sections, statistical distributions were sought to describe the randomness of different variates (variables) relevant to this paper. In each case, a goodness-of-fit test was performed using MATLAB to select the statistical distribution that best fits the variable. A brief account of the characteristics of each selected distribution is given in each case.
