ISO 18365:2013对湖泊、水库、河流或运河或其他人工明渠的水位或水位和流量测量站的建立和运行提出了要求。它还描述了使用所列测量方法之一的测量站应如何操作和维护。 对天然河道中的纯水位测量站、水位流量站和直接流量测量站以及带有人工结构的水位流量站提出了要求。此外，对于在困难条件下的测量，例如在结冰条件下，给出了一些要求。

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.
