LPMLE <i>n</i> –A Frequency Domain Method to Estimate Vertical Streambed Fluxes and Sediment Thermal Properties in Semi‐Infinite and Bounded Domains

This paper presents the LPMLEn, a new method to estimate vertical flux and thermal diffusivity from streambed temperature time series using frequency domain. The main advantages of this are: (a) use multiple frequencies sensors for parameter estimation; (b) noise/uncertainty handling in an optimal way; (c) possibility parameters with both semi-infinite bounded domain models; (d) compensation drifts data known as transients. capabilities LPMLEn are demonstrated synthetic field data, highlighting model over estimation process.
