This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. It provides guidance on the features and processes to be taken into account when characterizing and assessing the hydromorphology of rivers. It is based on methods developed, tested, and compared in Europe. Its main aim is to improve the comparability of hydromorphological assessment methods, data processing and interpretation. Although it has particular importa...view more

This standard considers liquid precipitation and defines a classification for catching-type RI measurement instruments based on their laboratory performance. Standardised calibration tests are described for the assessment of the accuracy of these raingauges both in the laboratory and in the field. The classification does not relate to the physical principle used for the measurement nor does it refer to the technical characteristics of the instrument assembly. The classification is solely based o...view more

ISO 35106:2017 specifies requirements and provides recommendations and guidance for the collection, analysis and presentation of relevant physical environmental data for activities of the petroleum and natural gas industries in arctic and cold regions. Activities include design and operations, which involve planning and actual execution.
Reference to arctic and cold regions in this document is deemed to include both the Arctic and other locations characterized by low ambient temperatures and th...view more

This document considers liquid atmospheric precipitation and defines the procedures and equipment to perform laboratory and field tests, in steady-state conditions, for the calibration, check and metrological confirmation of liquid precipitation measurement instruments. It provides a classification of catching-type measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technica...view more

This document provides guidance for survey design, equipment specification, survey methods, sampling and data handling of macroalgae and marine angiosperms such as Zostera in the intertidal soft bottom environment. It does not include polyeuryhaline terrestrial angiosperms that are found in saltmarshes. Ruppia is a genus of angiosperms that can be found in brackish water. This document can also be applied to the study of Ruppia in these environments.
The document comprises:

This document gives guidances on determining the degree of modification of the hydromorphological features of transitional and coastal waters

ISO 19926-1:2019 specifies system performance of ground-based weather radar systems measuring the atmosphere using frequencies between 2 GHz and 10 GHz. These systems are suitable for the area-wide detection of precipitation and other meteorological targets at different altitudes. This document also describes ways to verify the different aspects of system performance, including infrastructure. ISO 19926-1:2019 is applicable to linear polarization parabolic radar systems, dual-polarization and si...view more

This European Standard provides guidance on characterizing the modifications of the hydromorphological features of TraC waters described in EN 16503, enabling consistent comparisons of hydromorphological modification between TraC waters within a country and between different countries in Europe. Its primary aim is to assess ‘departure from naturalness’ as a result of human pressures on TraC hydromorphology, and it suggests suitable sources of information that may contribute to describing the mod...view more

This document specifies the requirements and performance test procedures for monostatic heterodyne continuous-wave (CW) Doppler lidar techniques and presents their advantages and limitations. The term "Doppler lidar" used in this document applies solely to monostatic heterodyne CW lidar systems retrieving wind measurements from the scattering of laser light by aerosols in the atmosphere. Performances and limits are described based on standard atmospheric conditions. This document describes the d...view more

This European Standard gives recommendations for the management of observed hydrometric data, including raw data
and other data and statistics derived from these observations.

The present document specifies technical characteristics and methods of measurements for digitally modulated
radiosondes operating in the range from 1 668,4 MHz to 1 690 MHz.
NOTE 1: The present document does not cover radiosondes with an imbedded receiver.
NOTE 2: The relationship between the present document and essential requirements of article 3.2 of Directive
2014/53/EU [i.1] is given in annex A.

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 sometimes flow, are measured includes lakes, reservoirs...view more
