Some properties of water-clay dispersions and their effects on flow and sand transport phenomena
Fine sediments dispersed in water affect the apparent viscosity and specific weight of the resulting dispersion. Tests at 24 degrees centigrade with a Stormer viscosimeter showed that the apparent kinematic viscosity for a 10 percent by weight water-clay dispersion of an impure bentonite was 8.75 times greater than that of distilled water. A 10 percent water-kaolin dispersion was 1.40 times more viscous than distilled water. The change in viscosity and density of the water-fine sediment dispersion changes the fall velocity of the bed material. The fall velocity distribution of the bed material ...
