Description: The widening use of sediment surrogate measurements such as turbidity necessitates consideration of new methods for estimating sediment flux. Generally, existing methods can be simply be used in new ways. The effectiveness of a method varies according to the quality of the surrogate data and its relation to suspended sediment concentration (SSC). For this discussion, it is assumed that for each estimated period the surrogate data are accompanied by corresponding SSC data. If they are not, then the suspended sediment flux (i.e. yield or load) estimates are likely to be very poor. The accuracy of estimates is probably more dependent on sampling design and data quality than on the estimation method (Eads, 2002)
