In this study, measured flow data obtained from natural streams is utilized to predict hydraulic characteristics and to validate conformity of the measured data sets. Section factor is computed from cross-section measurements. Relations between section factor and water depth are derived from synthetically enriched data based on measurements at high water levels. Bed friction and bed slope are determined by fitting logarithmic law to measured point velocity data. Thus, it's shown that it can be possible to obtain more technical information from the traditional flow measurement data.
