The Median Routing Study Method Applied to the 1947 Condition of the Pecos River Compact.

Abstract : The model developed in this report is a new robust statistical methodology for achieving monthly routing studies. The model automatically and objectively makes best fit adjustment to montly data so that mass balance is preserved, so that the monthly adjusted data are as close as possible to recorded monthly data, and so that the estimates add up as closely as possible to yearly totals. The model is of constrained median form. It simultaneously estimates new losses, reservoir storage, spills, flood inflows, etc. For computation the model is piece-wise linearized so that LP methods can be employed. It is applied to the Pecos River between Texas and New Mexico. Comparison is made between its results and those of two other methods applied earlier to the Pecos River. (Author)
