A series of settling tests and physico-chemical property tests on Saemankeum fine-cohesive sediments has been conducted in order to investigate the correlation between settling properties and their physico-chemical properties which are represented as grain size distribution, mineralogical composition, and percentage of organic contents. Experimental results of physico-chemical property tests show that Saemankeum sediments are relatively large in average grain size(52${mu}{ extrm}{m}$), and contain very small organic materials(2%), and are dominantly composed of Quarts in mineralogical aspect which has relatively low cohesion. Thus, Saemankeum sediments might be specified as the sediments whose settling properties are more influenced by the gravity than the cohesion. This characteristics of Saemankeum sediments are found to lead to relatively small settling velocity in flocculated settling region in which increasing cohesion results in increasing settling velocity, while relatively large settling velocity in hindered settling region in which settling velocity decreases with increasing cohesion. |
