Description
Another executable-based analysi included in CFA is the Load Estimator which is a tool (LOADEST) developed by the U.S. Geological Survey (Runkel et al. 2004). LOADEST is a FORTRAN executable that estimates the amount of constituent loads in streams and rivers given a time series of stream flows and constituent concentrations. Estimation of constituent loads occurs in two steps, the calibration procedure and the estimation procedure, both of which are based on three statistical estimation methods. These methods are Adjusted Maximum Likelihood Estimation (AMLE), Maximum Likelihood Estimation (MLE) and Least Absolute Deviation (LAD). The first two methods are appropriate when the calibration model errors, or residuals, are normally distributed. Of these two, AMLE is best utilized when the calibration data (i.e. stream flow and constituent concentration) are censored. The LAD is an alternative to maximum likelihood estimation when the residuals are not normally distributed.

In the calibration step, known constituent concentrations with corresponding stream flows are used to calibrate LOADEST so that it may be determined which of the preloaded models in LOADEST may best be used for determining the load. Next, in the estimation step, all of the known stream flows are used to estimate loads of constituent for each day. Please note that the names of the output file are dynamically determined by the water quality test analyzed.
