The mass density of water has become dependent not only on the temperature by changing it, but also on the turbidity. The more turbidity of the water increases, the suspended matter, the sediments carried, and the portable pollutants as well. This increases the density of the water or changes it, and in addition to that the salts dissolved in the water also change the density, so the density of salt and materials mix with the density of the water, becoming The density of a solution and not the density of water, so it must be taken into account when linking relationships and equations with each other. Turbidity and suspended sediments are considered pollutants. Density has become dependent on several determinants, including temperature, turbidity, concentration of dissolved salts, and bottom load, which depends on the amount and depth of the coming water. It is thrown and taken from the river, and you discuss with thanks and appreciation
