Figure 8.3b. Liquid limit variation across the study area for the depth of
0,50m and greater (north-south distance: 4000 m).
The distribution is generally similar along the five field profiles, both at depths of less than
0,50m and those of 0,50m and deeper. The profiles A, B, C, D and E exhibit liquid limit
values of 78-93%, 81-89%, 76-88%, 80-85% and 81-88% for depths of less than 0,50m; and
75-90%, 72-91%, 80-89%, 84-90% and 83-90% for depths of 0,50m and greater.
The distribution and variation of liquid limit at depths of 0,50m and those at 0,50m and
greater across the study area are generally similar, being characterised by maximum and
minimum values of 93% and 76% with a range of 17%; and 91% and 72% with a range of
19%, respectively (Table 8.1).
