THE PURPOSE OF THIS PAPER WAS TO PRESENT THE CONCEPT OF ADOPTING FLOOD FLOW FREQUENCY RELATIONSHIPS AT UNGAGED LOCATIONS BASED ON ALL THE AVAILABLE INFORMATION. This method essentially compares the flood flow frequency results of various procedures and adopts a function which may constitute the results of one procedure or may be a constructed function which in its entirety is none of those analytically or otherwise determined. The emphasis was placed on the need of the professional performing the analysis to understand available procedures, study considerations which affect the analysis and utilization of field reconnaissance information, all of which influence the evaluation process and subsequent reliability of the results. An appendix is included which describes in detail selected categories of procedures commonly used in analysis of flood flow frequency relationships for ungaged locations. The appendix includes descriptions of the methodologies involved in using the individual procedures and lists the primary advantages and limitations of each. The use of the adopted frequency curve concept provides insight as to the variability and reliability of the results, places proper emphasis on the end product, the frequency curve, and generally results in better flood flow frequency estimates.
