Abstract

Continuous monitoring of stream discharge, a vital variable for water resources, benefits from a long history of development and successive performance improvements. To date, there are well-established measurement protocols allowing to continuously measure with high accuracy steady flows. However, during unsteady flows, these methods are challenged irrespective of their approaches (i.e., stage-discharge, index-velocity, and slope-area). This study compares discharge estimates provided by conventional methods for discharge monitoring with measurements acquired in-situ with alternative instruments and methods. The measurements are acquired in a medium- and small-size stream using protocols widely used in the hydrometric community. The acquisition of such experimental evidence can support the sound evaluation of the methods' performance in steady flows and unsteady flows. While the datasets are limited and site specific, the inferences from the study can guide the design of comprehensive, end-to-end uncertainty analyses.
