Salt flats or sabkhas are coastal and inland salt bearing arid climate sediments.
These types of soils are encountered in arid regions throughout the world including
Australia (Akpokodje,1985),the United States (Kinsman,1969; Lund et al.,1990),
but predominantly found in vast areas of the coasts of Middle Eastern and North
African countries (Johnson et al.,1978; Akili,1981; Khan and Hasnain,1981;
Stipho,1985; Dhowian et al.,1987; Al-Amoudi et al.,1991).The development of this
material is due to low wave energy allowing the settlement of silt and clay particles to
take place and then be loosely cemented by soluble materials (Akili,1981; James and
Little,1994).
In general,sabkha deposits have high void ratios,and invariably contain an
appreciable amount of organic materials.Accordingly,they are characterised by
being highly compressible with low bearing resistance.Laboratory test results,

substantiated by the relatively large settlements measured under instrumented test
embankments,indicated that preloading is an effective technique that can eliminate
the primary consolidation settlements and reduce the secondary compressions of
sabkha sediments (Juillie and Sherwood,1983; Dhowian et al.,1987; Al-Shamrani
and Dhowian,1997).
Different criteria are used to monitor and evaluate improvement of soils by
preloading,but the attained average degree of consolidation from settlement records
is considered the most widely used criterion (Hansbo,1981).However,it requires
reliable estimate of the potential ultimate settlement in order to predict the rate of
settlement under the fill,and hence determine the amount of surcharge necessary
to achieve the required settlement in a time that is acceptable.Beside its importance
in planning of preloading,reliable estimate of settlements is an important aspect for
monitoring field settlements as construction progresses,and hence permitting any
significant variation to be immediately noticed before the construction proceeds
too far.
