The settling rate of the dredged soil may vary with mineral composition, grain size distribution, initial con contration and salt concentration of suspension of the site. A series of settling column test was performed to investigate the settling rate characteristics of solid suspension material from dredging and reclamation. The settling rate of soil mixed with various size of particles depended on clay fraction which showed a inherent flux. A model was developed to predict the particle flux of mixed soil from the clay flux and its applicability was verified.

The liquid limit(LL) test is universally used as a standard test for determining one of the index properties of a clay. There are two methods of determining the LL, Casagrande method and cone penetration method that is fall cone test. The interpretation of the Casagrande method of obtaining the LL is not obvious, but it has been suggested that the fall cone test is essentially a strength test and that the LL test simply ascertains the moisture content at which a clay has a certain standard undrained shear strength. This paper presents a determination of the LL by a single-point method. Results obtained from fall cone that is general method and a single-point method are analyzed by comparison.
