Record 1 2016-08-12

English

Subject field(s)
  • Hydrology and Hydrography
DEF

A stream in which over a period of years, slope is delicately adjusted to provide, with the available discharge and with prevailing channel characteristics, just the velocity required for the transportation of the load supplied from the drainage basin.

OBS

The graded stream is a system in equilibrium.

French

Domaine(s)
  • Hydrologie et hydrographie
DEF

Cours d'eau qui [a] apparemment atteint, sur de longs parcours, un état que l'on peut pratiquement qualifier d'équilibre entre le débit solide et le débit d'apport de sédiments.

Spanish

Campo(s) temático(s)
  • Hidrología e hidrografía
DEF

Curso de agua que ha alcanzado aparentemente un estado aproximado de equilibrio entre las tasas de aporte y transporte de sedimentos.

Record 2 2012-04-05

English

Subject field(s)
  • Hydrology and Hydrography
DEF

A place of abrupt change in a stream gradient.

CONT

Every stream develops its own gradient and establishes a longitudinal profile. A portion of the stream is designated a graded stream when the stream is adjusted among available discharge, channel characteristics, its velocity, and the load supplied from the drainage basin. An interruption in a stream's longitudinal profile is called a nickpoint. A nickpoint can develop as the stream flows across hard resistant rock or after tectonic uplift episodes.

Key term(s)
  • knick point

French

Domaine(s)
  • Hydrologie et hydrographie
CONT

Tout cours d’eau à l’équilibre présente un profil longitudinal caractéristique d’allureconcave. On désigne par le terme de rupture de pente le changement brusque de ce profil. Des indices peuvent être calculés pour quantifier cette irrégularité.

Record 3 2011-12-12

English

Subject field(s)
  • Geomorphology and Geomorphogeny
DEF

A landform that can result when a natural (or artificial) levee is breached, usually during a flood, in one location.

CONT

A crevasse splay is a geographical feature which forms when an overloaded stream breaks a natural or artificial levee and deposits sediment on a floodplain. This breach can cause large deposits that spread in a pattern similar to that of a river delta. In other words, coarser sediment is deposited first, close to the breach while finer sediment is carried farther to the edges of the crevasse splay. In cross section, the crevasse splay will result in graded deposits which may look like a Bouma sequence.

CONT

Crevasse splays are essentially small lobate deltas forming within the framework of the larger delta. They consist of relatively thin, lens-like masses of sediment, showing small-scale prograding coarsening-upward sequences ...

OBS

crevasse splay: term used at Natural Resources Canada - Earth Sciences Sector.

French

Domaine(s)
  • Géomorphologie et géomorphogénie
DEF

Corps silto-sableux provenant de l'épandage du matériel fluvio-deltaïque, s'étalant en bordure de chenal au travers de brèches entaillées dans les levées des chenaux distributaires, et formant des éventails dans l'embouchure des deltas.

CONT

Les faciès argileux sont interprétés comme des dépôts de plaine d'inondation soumise épisodiquement à des épandages de crevasses («crevasse splay») lors des crues, par rupture de levées.

OBS

crevasse évasée; crevasse divergente : termes en usage à Ressources naturelles Canada - Secteur des sciences de la Terre.

Record 4 2006-10-26

English

Subject field(s)
  • Toponymy
  • Geomorphology and Geomorphogeny
DEF

Deep, steeply graded, V-shaped declivity, sometimes containing a stream.

CONT

Bears Paw Gulch, Man.

OBS

Widely used. Generally smaller than a ravine but larger than a gully. Yukon use is in gold mining areas of the late 1890s.

OBS

gulch: term and definition validated by the Canadian Permanent Committee on Geographical Names (CPCGN) within the scope of its glossary (BT-176) which is the first authoritative publication on generics in use in Canada.

French

Domaine(s)
  • Toponymie
  • Géomorphologie et géomorphogénie
DEF

Petit ravin.

CONT

La Grande Ravine. Qué.

OBS

La ravine est plus petite que le ravin et la vallée. Attesté au Qué.

OBS

ravine : terme et définition uniformisés par le Comité permanent canadien des noms géographiques (CPCNG) dans le cadre du glossaire BT-176 faisant autorité sur la question des génériques en usage au Canada.

Record 5 1999-05-13

English

Subject field(s)
  • Geomorphology and Geomorphogeny
  • Physical Geography (General)
  • Hydrology and Hydrography
DEF

The longitudinal profile of a graded stream or of one whose smooth gradient at every point is just sufficient to enable the stream to transport the load of sediment made available to it. It is generally regarded as a smooth, parabolic curve, gently concave to the sky, practically flat at the mouth and steepening toward the source; but current thought is that it need not be smooth.

French

Domaine(s)
  • Géomorphologie et géomorphogénie
  • Géographie physique (Généralités)
  • Hydrologie et hydrographie
DEF

Pente du lit de la rivière assurant avec le minimum de travail l'écoulement des eaux et le transport des matériaux. Le travail de la rivière représente un véritable système d'autorégulation où en chaque pente du lit, à chaque instant, un équilibre s'établit entre la force de la rivière (débit et vitesse), sa charge et son lit.
