ACCURACY OF STREAMFLOW CHARACTERISTICS IN GEOLOGICAL SURVEY RESEARCH 1969, CHAPTER D: U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 650-D by C.H. Hardison Prepared by the U.S. Geological Survey U.S. Geological Survey Professional Paper 650-D TABLE OF CONTENTS Abstract Accuracy of the Mean Accuracy of the Standard Deviation Accuracy of an Estimated T-Year Event Use of the Relationship Curves References ABSTRACT Streamflow information, which is one of the end products of the Water Resources Division of the U.S. Geological Survey, may be obtained directly from a streamflow record or may be derived from base data by analytical methods. In either case, accuracy goals for the information obtained are needed to test the adequacy of the information and to design the data-collection system upon which the information is based. It is proposed that the accuracy goal for each streamflow chacteristic be set equivalent to the accuracy with which that characteristic could be estimated from an observed record of some stipulated lengths. Curves and tables are presented in this paper to aid in setting such goals. LizardTech's Djvu plug-in is needed to view these reports.
