本实验室研究了塞西尔Ap土壤的浊度（NTU）和总悬浮沉积物浓度（TSS, mg/L）之间的关系，塞西尔Ap土壤是一种常见的东南山前土壤类型。我们发现淤泥和粘土组分的NTU和TSS之间的相关性为1:1，但粘土和散装土样品的比例较小。这些结果表明，NTU测量可用于估计细粒土壤组分的沉积物浓度，但低估了沙粒组分存在时的总沉积物浓度。
This laboratory work examines the relationship between turbidity (NTU) and total suspended sediment concentration (TSS, mg/L) for a Cecil Ap soil, a common Southeastern Piedmont soil type. We show a 1:1 correlation between NTU and TSS for the silt and clay fractions, but a smaller ratio for clay and bulk-soil samples. These results suggest that NTU measurements can be used to estimate sediment concentrations for fine soil fractions, but underestimates the total sediment concentration when sand-size fractions are present.
