for the presence of peat water increases, resulting in lower resistivity in the peat envi-
ronment. Since the humification processes can increase the quantity of humus particles,
the higher degree of humification would decrease the resistivity (Asadi
et al
, 2009f,
Asadi, 2010).
3.13 CORRELATIONS BETWEEN INDEX PARAMETERS OF PEAT
As with mineral soils, correlations between various index parameters have also proved
to be useful for peat. Edil (2003) emphasized the importance of characterizing peat and
organic soils by certain index parameters to provide a basis for comparison of results
of mechanical tests. Hobbs (1986) also suggested that it is convenient to relate the
basic geotechnical properties of organic soils to some of the easily determined index
parameters, such as water content, organic content or liquid limits.
