Description
<p> The DLVO theory using the potential energy around the deposited sediment particles is defined by the sum of the intermolecular energy of the particles and the electrostatic repulsion energy. Thus, we hypothesised that if the surface potential of the bottom sediment particles is measured, the shear stress of the bottom sediment can be evaluated. In this study, we proposed a method to measure the surface potential of bottom sediment particles by utilizing the characteristics of metal electrodes and carbon electrode with semiconductor characteristics. It was experimentally confirmed that the surface potential of the sediment particles generated in the sedimentation process, consolidation and winding up can be directly measured.</p>
