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.

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.

Concrete Pavement ... The paver extrusion plate or screed shall extrude the concrete under load, properly shaping and compacting the concrete into a dense, stable mass.

CONT

The paver-finisher shall spread, consolidate, and shape the plastic concrete to the desired cross section in one pass. The paver-finisher shall be equipped with a full width "knock-down" auger, capable of operating in both directions, which will evenly spread the fresh concrete in front of the screed or extrusion plate.

Key term(s)

For array power performance(i. e., partially correlated WECS sites spread over a region such as utility service area), one additional parameter, the average spatial cross correlation, is sufficient to model the necessary array statistics.
