Discussion of 'Uncertainty Model for In Situ Quality Control of Stationary ADCP Open-Channel Discharge Measurement' by Hening Huang

摘要

Hydroscience is dealing with processes that are variable in time and space, making the measurement process difficult, prone to uncertainties, and, at times, even impossible to be captured with common instrumentation. For a long time, the hydroscience community has been screening and evaluating uncertainty analysis (UA) methodologies and frameworks that can be uniformly applied across the myriad of instruments and measurement situations encountered in routine and custom applications. The search for relevant UA methods is challenging because there is a multitude of UA approaches developed by various communities that are not fully harmonized in term of concepts, terminology, and protocols (Muste et al. 2012).
