Hydrometry - Selection, establishment and operation of a gauging station (ISO 18365:2013)

ISO 18365:2013 gives requirements for the establishment and operation of a gauging station for the measurement of stage, or stage and discharge, of a lake, reservoir, river or canal or other artificial open channel. It also describes how a gauging station utilising one of the measurement methods listed should be operated and maintained.
Requirements are provided for stage only measurement stations, stage-discharge stations and direct-discharge measurement stations in natural channels, as well as for stage-discharge stations with artificial structures. Additionally, some requirements are given for measurements under difficult conditions, such as under ice conditions.

Hydrometrie - Auswahl, Einrichtung und Betrieb einer Pegelstation (ISO 18365:2013)

Diese Internationale Norm enthält Anforderungen zur Einrichtung und zum Betrieb einer Pegelstation zum Messen des Wasserstands oder des Wasserstands und Durchflusses eines Sees, Stausees, Flusses, Kanals oder eines anderen künstlichen offenen Gerinnes. Sie beschreibt auch, wie eine Pegelstation, an der eine der aufgeführten Messverfahren angewendet wird, betrieben und unterhalten werden sollte.
Es werden Anforderungen für reine Wasserstands-Pegel, für Pegel mit Wasserstand-Durchfluss-Beziehung und für Pegel mit direkter Durchflussmessung in natürlichen Gerinnen sowie für Wasserstand-Durchfluss-Pegel mit Messbauwerken bereitgestellt. Zusätzlich werden einige Anforderungen zu Messungen unter schwierigen Bedingungen gegeben, wie zum Beispiel bei Eis.

Hydrométrie - Sélection, établissement et exploitation d'une station hydrométrique (ISO 18365:2013)

L'ISO 18365:2013 donne des exigences pour l'établissement et l'exploitation d'une station hydrométrique destinée à la mesure de la hauteur, ou de la hauteur et du débit, d'un lac, d'un réservoir, d'une rivière, d'un canal ou autre canal découvert artificiel. Elle décrit aussi la manière dont il convient d'exploiter et de maintenir une station hydrométrique utilisant une des méthodes de mesure citées.
Des exigences sont fournies pour les stations de mesurage de la hauteur seulement, les stations de mesurage hauteur-débit et les stations de mesurage direct du débit dans des canaux naturels, et aussi pour les stations de mesurage hauteur-débit avec des ouvrages artificiels. Des exigences sont données, en plus, pour les mesurages effectués dans des conditions difficiles, sous la glace par exemple.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
