Rheological Properties of a Natural Estuarine Mud

Rheological Properties of a Natural Estuarine Mud

In this paper, the linear and non-linear rheological properties of estuarine cohesive sediments were investigated. The density of the sediments has been determined by pycnometry. Creep and oscillatory shear measurements have been performed in order to determine i) the transitions in mechanical respo...
