Management of observed hydrometric data. Recommendations Ingestion-build-202139 — machines designed for highway1 Scope This document gives recommendations for the management of observed hydrometric data, including raw data and other data as well as statistics derived from these observations. Although the principles of data management can be applied to all hydrometric observations, particular focus is placed on measurements of precipitation, water level (including stage), volume and discharge in open channels. NOTE The range of sites where water levels, and
