Analysis on the Changes of Turbidity and Conductivity in the Lower Reaches of Jinsha River before and after the Construction of Guanyinyan Reservoir

By analyzing and comparing the monthly average monitoring data of the water quality automatic monitoring station in the lower reaches of Guanyinyan Reservoir, it was found that the electrical conductivity increased significantly after the construction of the reservoir, however, the turbidity decreased significantly. In addition, the periodicity of turbidity was enhanced, and the periodicity of electrical conductivity has become a trend after the reservoir was built.
