;:.. ,..,. :~':}~ ABSTRACT h ., l\) ~ This r~port describes the progress towards applying stochastic ~ hydrolqgy techniques for use in planning studies for the USBR. "-" The metho.;ls used to define and model flow and water quality time series'are detailed. Techniques used to extract coefficients for time s,ries representation and the procedure for synthesizing stocha$tic data from them are explained. The da~aana1ysis and synthesis procedures have been applied to stream~lows at major gaging stations in the Colorado River Basin. The co~fficients resulting from analysis of historic data are documehted. Adjustments and refinements needed to produce a con- sistent data set are discussed. " " w,,:\ Sever~l comparisons are made to illustrate the agreement between synthdtic and historic data. Tables and graphs showing specific numer~cal results are presented. A list of recommendations for further refinement of stochastic hydrology applications for USBR purpo_es is given, This ~eport represents an updated version of an earlier report of the s,me title issued July 1974 and authored by John D. Hendrick and Albert E. Gibbs. As a result, much of the material in this repor~ is taken directly from that report with little or no revi- sions~ Mowever, in the intervening time since the July 1974 versi9n, substantial gains in knowledge have been made. This along;with the numerous changes to the basic data has led to the conclhsion that a new report was required. This report has two objec~ives: ,first to provide a readily available source containing the p~e~ent data set and second to set down recommendations for improying the data generation techniques. No attempt will be made to du,\:>1icate all of the supporting material in the July 1974 report.
