Formulation and Its Verification of Conductivity for Uniform Turbid Water

For measurement of sediment spatial concentration of nearshore sea water, a turbid water system with several kinds of particles is investigated from the viewpoint of the characteristics of particles. Firstly, the classical physical and chemical conductivity formula is extended to macro-particle (such as sand) conductivity formula. Secondly, the Fricke formula suitable for only one kind of particles is extended to the conductivity formula suitable for several kinds of particles. Finally, the multi-particle conductivity formula is applied to the measurement of sediment spatial concentration.
