This document provides an understanding of the nature of measurement uncertainty and its significance in estimating the "quality" of a measurement or a determination in hydrometry. This document is applicable to flow measurements in natural and man-made channels. Rainfall measurements are not covered.
Abstract
Overview
EN :2022 - Hydrometric uncertainty guidance (HUG) provides practical guidance for understanding, estimating and reporting in hydrometry. Endorsed by CEN and identical to , this standard focuses on flow measurements in (open-channel flow and structures). It clarifies the nature of random and systematic effects and explains how to quantify the “quality” of a hydrometric measurement. .
