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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 772 was prepared by Technical Committee ISO/TC 113, Hydrometry.
This fifth edition cancels and replaces the fourth edition (ISO 772:1996), which has been technically revised. It
incorporates the Amendments ISO 772:1996/Amd.1:2002 and ISO 772:1996/Amd.2:2004.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux de
normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général confiée
aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du
comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI,
Partie 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur

Introduction
In the preparation of this International Standard, the following principles were adopted wherever possible:
a) to standardize suitable terms and symbols without perpetuating unsuitable ones;
b) to discard any term or symbol with differing meanings in different countries, or for different people, or for
the same person at different times, and to replace that term or symbol by one which has an unequivocal
meaning;
c) to exclude terms which are self-evident.
As far as possible terms in existing International Standards have been included; however, these terms may be
the subject of future amendments.
Note that similar or identical terms may have se

The CEN Secretary-General has advised the ISO Secretary-General that this ISO/DIS covers a subject
of interest to European standardization. In accordance with the ISO-lead mode of collaboration as
defined in the Vienna Agreement, consultation on this ISO/DIS has the same effect for CEN
members as would a CEN enquiry on a draft European Standard. Should this draft be accepted, a
final draft, established on the basis of comments received, will be submitted to a parallel two-month FDIS
vote in ISO and formal vote in CEN.
In accordance with the provisions of Council Resolution 15/1993 this document is circulated in
the English language only.
Conformément aux dispositions de la Résolution du Conseil 15/1993, ce document est distribué

ISO 772 was prepared by Technical Committee ISO/TC 113, Hydrometry, Subcommittee SC 3,
Terminology and symbols.
The 4th Edition of ISO 772 was brought out in 1996. Thereafter two amendments FDAM1 and FDAM2
were issued and some comments were received from the members. In view of the above, during the
last ISO/TC 113/SC3 held on 20th May, 2004 at Tsukuba, Japan, it was decided to revise ISO
772:1996. The Subcommittee also decided to prepare the revised document in English only.
This fifth edition cancels and replaces the fourth edition (ISO 772:1996) which has been technically
revised.
Annex A forms an integral part of this international standard. Annex B and C are for information only.

Introduction
In the preparation of this International Standard, the following three principles were adopted wherever
possible.
a) to standardize suitable terms and symbols without perpetuating unsuitable ones;
b) to discard any term or symbol with differing meanings in different countries, or by different people,
or by the same person at different times, and to replace that term or symbol by one which has an
unequivocal meaning;
c) to exclude terms which are self-evident.
It is recognized that it is not possible to produce a complete set of definitions which will be universally
acceptable, but it is hoped that the definitions provided and the symbols used will find widespread
acceptance and that their use will lead to better understanding of the practice of hydrometric
determinations.
DRAFT INTERNATIONAL STANDARD ISO/DIS 772: 2006
Hydrometry — Vocabulary and symbols
1 Scope
This International Standards gives terms, definitions and symbols in English and used in the field of
hydrometric determinations.
Structure of the Vocabulary
The terminology entries are presented in systematic order, grouped into sections according to
particular methods of determination or in relation to particular subjects. Annex A lists the symbols
used in this international Standard. Annex B refers the user to ISO 3454 for statistical terminology,
and to ISO 5168 for more extensive information about the evaluation of uncertainties. An alphabetical
index is included at the end.
The structure of each entry is in accordance with ISO 10241, International terminology standards –
Preparation and layout. Country codes are in accordance with ISO 3166, Codes for the representation
of names of countries.
General terms
1.1
liquid flow
movement of a volume of a substance that is neither a solid nor a gas, that is practically
incompressible, that offers insignificant resistance to change of shape and that flows freely
Example:
Water or water with sediment.
1.2
flow regime
state of flow in alluvial streams characterized by a bed configuration of ripples, dunes (lower regime),
plane bed (transition), standing waves and antidunes (upper regime)
NOTE The lower regime flow is sub-critical; the upper regime flow is supercritical.
1.3
steady flow
condition in which the discharge does not change in magnitude with respect to time
1.4
unsteady flow
condition in which the discharge changes in magnitude with respect to time
1.5
uniform flow
flow, in an open channel, in which the depth and velocity remain constant along the open channel
NOTE For uniform flow, the velocity vector is constant along every stream line. Uniform flow is possible only
in an open channel of constant cross-section.
ISO/DIS 772: 2006
1.6
critical flow
flow in an open channel, in which the specific energy is a minimum for a given discharge
NOTE Under this condition the Froude number is equal to unity and small surface disturbances cannot
travel upstream.
1.7
subcritical
