In this master of science thesis study, sieve analysis, specific gravity, wet analysis, liquid and plastic limit tests, soil classification tests, standard compaction tests and falling head permeability tests are performed over five different soil samples taken from various places in Trabzon are examined. At the end of the soil classification tests, the soil samples are classified according to the Unified Soil Classification System (USCS). After standard compaction tests, it was found that dry density of soil increased with increasing water content. Until peak point where dry density is maximum and water content is optimum, dry density has maximum value and peak point, the dry density decreases with increasing water content. Moreover, in parallel with amount of increase of fine grained soils, it was found that optimum water content value decreases, and, maximum dry densities increase. As a result of falling head permeability tests, it was found that coefficient of permeabilities decrease with increasing water contents before in the 1st region. In the 2nd region, coefficient of permeabilities became minimum, with the increasing water contents, increase in the coefficient of permeabilities were observed in 3 rd region. Water content-dry density (w-pk) and water content-coefficient of permeability graphs are unified. It was seen that the water content of maximum dry density and minimum permeability is nearly the same. It is determined that the graph of void ratio-coefficient permeability (e-log k ) which is obtained from compaction tests and falling head tests is linear.
