Hydrometric uncertainty guidance (HUG) (ISO 25377:2020)

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.

Leitfaden zu Messunsicherheiten in der Hydrometrie (HUG) (ISO 25377:2020)

Dieses Dokument bietet einen Beitrag zum Verständnis der Natur der Messunsicherheit und deren Bedeutung bei der Abschätzung der „Qualität“ einer Messung oder einer Bestimmung in der Hydrometrie.
Dieses Dokument ist anwendbar für Abflussmessungen in natürlichen und künstlichen Gerinnen. Messungen der Niederschlagsmenge werden nicht berücksichtigt.
