Characteristics of the silt particles and reflection spectrum of the yellow water at the mouth of the Yellow River

We had a synthetic survey and test to the Yellow River water on the Ke-Ling I ship near the mouth of the Yellow River, which includes the test to the Yellow River water spectrum reflectivity by using WFH2.5 near infrared spectrometer and the water sample collection. In the laboratory we analyzed the water sample by the photoelectric method and obtained the percentage of sample's silt diameter to the silt weight, middle-number silt diameter and silt content etc. Besides, we also obtained the spectrum reflectivity curve of the relevant water sample by the calculation.
