This paper deals with the effects of moisture content on strength of older alluvium under dry, wet and saturated
conditions. Older alluvium is semi cemented sediments eroded, deposited and reshaped by water in non-marine
setting. Specimens were tested for shear strength, hardness and point load index. According to the results, the
petrophysical properties of older alluvium decrease with increasing moisture. The strength was severely reduced
after the moisture content was increased over the range of natural moisture content i.e. at saturated condition.
However, due to difficulties and non reliable preparation of regular samples at the laboratory, most of the samples
were destroyed during the sample preparation. Point load apparatus and Schmidt (rebound) hammer test did not
record any reading during the test of the samples for both wet and dry condition. Older alluvium shows equal
proportion of clay/silt and gravel with percent finer of approximately 38% and 38.5% respectively, and lower sand
contents with percent finer of approximately 23.4%. The range of natural moisture content is from 17.98 to 19.65%.
The results revealed that moisture content have great influence in the reduction of the shear strength τ, friction angle
Ø and cohesion c.
