ISO 6420:2016 specifies methods of determining the position of hydrometric boats based on satellite navigation systems and/or with respect to known points on the banks of rivers, estuaries or lakes. It applies to electronic positioning equipment and conventional surveying techniques.
Abstract
Overview
ISO 6420:2016 - Hydrometry: Position fixing equipment for hydrometric boats specifies methods to determine the position of boats used in hydrometric work. It covers procedures using satellite navigation systems (GNSS) and conventional surveying relative to known bank points. The standard applies to both electronic positioning equipment and traditional surveying techniques for tasks such as streamgauging, sediment sampling and morphological surveys of rivers, estuaries, lakes and reservoirs.
Key topics and requirements
- Scope and applications: Position fixing for discharge measurements, vertical placement for velocity/depth observations, suspended-sediment and bedload sampling, and morphological (bathymetric) surveys.
- Tapes and tag lines: Guidance on use and limitations. Typical practice includes steel measuring tapes for channels
