0.1 Inclusions

This Standard applies to methods to formulate and interpret IDF curves in a climate change context and includes consideration of methods for establishing historical IDF rainfall estimates and approaches and methods for incorporating climate change into IDF information.

0.2 Users and applicability

The target audience for this NSC are engineers involved in the mapping of floodplains and the design and build of stormwater infrastructure, as well as water resource managers involved in the operation and maintenance of such infrastructure. Another category of users consists of those involved in the collection and provision of climate and weather-related information and data. Other potential users include urban planners and policy makers. An example of a use by the latter would be using IDF curves to inform emergency preparedness policies and practices as it relates to flooding.

0.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material where appropriate. This Standard uses concepts from the climatological and statistical sciences that do not commonly appear in standards, and thus the text contains more explanatory material than is customary.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

0.1 Inclusions

Cette norme s’applique aux méthodes de formulation et d’interprétation des courbes IDF dans le contexte des changements climatiques et intègre des réflexions à propos des approches et des méthodes d’établissement des estimations IDF de précipitations historiques afin de tenir compte des changements climatiques dans les données IDF.

0.2 Utilisateurs et applications

Le public cible de cette NNC correspond aux ingénieurs travaillant sur la cartographie des plaines inondables et la conception ou la construction des infrastructures pluviales ainsi que les gestionnaires des ressources en eau associés à l’utilisation et à la maintenance de telles infrastructures. Une autre catégorie d’utilisateurs concernés est les personnes impliquées dans la collecte et la mise à disposition de données et d’informations reliées au climat et à la météo. D’autres utilisateurs potentiels de la norme sont les urbanistes et les décideurs. Par exemple, ce dernier groupe d’utilisateurs est susceptible d’employer les courbes IDF pour informer les politiques et pratiques de préparation en cas d’urgence en situation d’inondation.

0.3 Terminologie

Dans cette norme, le terme « doit » indique une exigence, c.-à-d une prescription que l’utilisateur est obligé à respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.

Les notes qui accompagnent les articles ne comprennent pas de prescriptions ni de recommandations. Elles servent à séparer du texte les explications ou les renseignements qui ne font pas proprement partie de la norme, le cas échéant. Cette norme utilise des concepts de la climatologie et des statistiques qui ne se trouvent pas couramment dans ce genre de document. C’est pourquoi elle présente plus de texte explicatif qu’à l’habitude.

Les notes au bas des figures et des tableaux font partie de ceux-ci et peuvent être rédigées comme des prescriptions.

Les annexes sont qualifiées de normatives (obligatoires) ou d’informatives (facultatives) pour en préciser l’application.
