This ,sand, was selected based on its hydraulic properties (i.e., air‐entry ,suction,) so as to allow the development of an unsaturated zone within the available height of the soil tank. The grain density of the ,sand, is 2650 kg m −3 , with a dominant mineral composition of quartz (99.8%).

The dynamics of the flow in the fluid ,model, must accurately simulate those in the field. Similarity criteria are derived through analysis of the equations of motion. This analysis shows that various nondimensional parameters must be matched between the ,model, and field flows. The ,significance, of each of these parameters is discussed in detail.

The study is intended to simplify the process of analyzing ,suction, piles from 3D to 2D ,model,. The research focuses on obtaining the coefficient to be applied into the 2D ,model, in order to obtain results that are as close as possible to the 3D ,model,. Two 2D models were used in the analysis, namely the plane strain and axisymmetric models.

The direct measurement is a method that uses equipment (e.g., pressure plate and tensiometer) to measure the water content of the soil under a certain matric ,suction,. This method can only measure SWCCs in a specific state (the same dry density or void ratio). Also, it is difficult to use a single method to measure SWCCs in the full ,suction, range.

The ,sand, is then washed, repacked, and flooded with sludge. A vacuum is then applied to the system. With a coarse media such as Ottawa ,sand,, there is likely to be some penetration of sludge into the media at higher vacuums. The ,sand, depth is experimentally adjusted to insure against sludge penetra- tion through the filter disk.

This site, with dimensions of approximately 900 m by 300 m, was first licensed for ,sand, and gravel extraction in 1971, with a peak in extraction activity recorded as 872 000 t in 1974. Extraction continued at levels >100 000 t per annum until 1995, before the site was relinquished by the industry in 1996.
