HISTORIC DATA [6 records]

Record 1 2010-10-20

English

Subject field(s)
  • Ecology (General)
  • Environmental Studies and Analyses
  • Hydrology and Hydrography
DEF

... a method developed by the US Fish and Wildlife Service for calculating summertime streamflow recommendations based on median monthly mean flows for August.

CONT

Used primarily in New England, the Aquatic Base Flow method uses historic flow data to determine the median flow for the lowest flow month(typically August or September), and applies that level to the remainder of the year... This approach assumes that a specific flow rate per unit of watershed area will provide an adequate minimum flow. It is simple to use, if historic data is available, but cannot account easily for site-specific biological concerns; nor can the method adequately and defensibly adjust for spawning or incubation.

OBS

The "default" ABF recommendation for summertime flows is 0.5 cubic feet per second per square mile of drainage area.

OBS

Baseflow: the discharge of groundwater from the zone of saturation to surface water bodies, such as lakes and streams.

Key term(s)
  • aquatic baseflow method
  • aquatic base-flow method
  • New England aquatic baseflow method
  • New England aquatic base-flow method
  • New England aquatic base flow method

OBS

débit de base : Débit d'un cours d'eau particulier à un moment de l'année où il n'y a ni pluie ni fonte des neiges, habituellement, la quantité d'eau souterraine déchargée dans un cours d'eau.

Record 2 2007-11-05

English

Subject field(s)
  • Historical Park and Site Names
OBS

The data, taken from a written source, should not include "Québec, "nor should it be a "National Historic Park. "No such park still exists in Canada, all having become a "National Historic Site of Canada. "The park, located on the Plains of Abraham in the town of Québec, is rather named : National Battlefields Park.

OBS

The site of many clashes for supremacy between the French and British Empires, the park is the scene of the 1759 Conquest, which changed the fate of North America.

Key term(s)
  • Plains of Abraham National Battlefields Park

French

Domaine(s)
  • Noms de parcs, lieux et canaux historiques
OBS

La donnée extraite de la source écrite est le fruit d'une inversion. Le nom correct de ce parc aurait dû être rétabli et se lire, conformément aux règles d'écriture : parc historique national des Champs-de-Bataille-Nationaux, à Québec. Cependant, il n'existe plus de «parcs historiques nationaux», tous étant devenus «lieu historique national du Canada», administré ou non par Parcs Canada. Ce parc se nomme plutôt le «parc des Champs-de-Batailles-Nationaux»; il est situé à Québec, sur les plaines d'Abraham.

OBS

Lieu d'affrontement des Empires français et anglais en quête d'hégémonie, le parc fût le théâtre de luttes dont l'issue, la Conquête de 1759, a changé le sort de l'Amérique.

Record 4 2002-07-22

English

Subject field(s)
  • Transportation of the Future
  • Signalling (Road Transport)
CONT

Traditional signal control systems use pre-stored timing plans that have been developed offline using historic data. These systems are not responsive to dynamic and volitile traffic demands, and deteriorate in performance over time. Adaptive traffic signal control systems are able to adapt to actual traffic conditions, coping with complex flow patterns and unpredictable variations. They seek continuous optimal system performance.

French

Domaine(s)
  • Transports futuristes
  • Signalisation routière
DEF

Système de régulation adaptative des feux de circulation pour la modification immédiate de la synchronisation des feux en vue d'optimiser l'écoulement de la circulation.

English

Subject field(s)
  • Statistics
  • Air Pollution
  • Meteorology
  • Hydrology and Hydrography
DEF

Any data that have been accumulated from prior periods.

CONT

The causal relationship between certain detrimental effects and acid precipitation, including its accompanying pollutants, can usually be proven by means of comparisons using historical or chronological data or by means of experiments in laboratories.

CONT

... scientists are using models based on fragmentary historical data or paleolimnology. ... One has to be careful in using historical data. First, methods of measurement may have been different, or even imperfect, so as to give deviating results. And even if chronological data show increasing acidification, this might be a natural process for the region involved, although this is not very likely.

CONT

The Fuzzy Temporal Relational database provides a structure for incorporating current and historical information on student’s knowledge, performance capabilities, instructional goals, etc.

French

Domaine(s)
  • Statistique
  • Pollution de l'air
  • Météorologie
  • Hydrologie et hydrographie
CONT

[...] la concentration en sulfate, en aluminium et en manganèse augmente tandis que le pH et l'alcalinité diminuent. Il est donc possible en étudiant l'évolution de la qualité de l'eau d'identifier les lacs en voie d'acidification ou acidifiés. Malheureusement, les données historiques sont souvent incomplètes ou imprécises.

OBS

Selon M. Richard Adams de la section de traduction de Statistique Canada, on emploie maintenant données historiques au lieu de données chronologiques.
