Table 5: Statistical analysis (median and standard deviation) of influence of initial conditions to the particle size distribution (obtained by LD) for the samples from the plot with slope 34\({}^{\circ}\) [%]. each fraction size were created (Tables A6-A8). The difference shows aggregate representation percentage in the sample. It is shown that with a later sampling time the median values of aggregate representation decreased on the 30 degand 34 deg slopes and increased on the 22 deg slope. Furthermore, for particles smaller than 2 and 10 um, the largest differences during the first part of the experiments (D1 and W1) had samples eroded from the slope 30 deg (18.8%, 14.1%, 34.0%, and 29.1%, respectively), while during the second part (D2 and W2) it was the samples from the 22 deg slope (13.0%, 14.3% and 28.4%, 29.8%, respectively). For the particles smaller than 50 um, the samples from the slope 34 deg exhibited the least differences (38.0%, 37.1%, 35.0%, and 36.1% for samples D1, W1, D2, and W2, respectively) and the samples from the slope 30 deg the largest differences (45.5%, 43.1%, 43.7%, and 42.0% for samples D1, W1, D2, and W2, respectively).
