Estimating Coefficients of a Flow Generator for Monotone Samples of Data

If a set of flow records continuous in collection to the present has different starting times, it forms a monotone sample. The monotone sample may yield an inconsistent lag zero covariance matrix. In addition, it may be impossible to calculate real‐value coefficients for a flow generator, leading to some complex values for the synthetic flow trace. A technique is presented that produces a consistent lag zero covariance matrix and a real‐value multisite streamflow generator.
