FREE GROUND WATER [9 records]

Record 1 2007-09-28

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

Glide avalanches ... occur mostly in very steep rock slabs during very warm weather. Glide avalanches are relatively difficult for a person to trigger and they tend to release more or less randomly in time. Paradoxically, they tend to release during the coldest part of the day, or during a freeze following a protracted period of melting ...

CONT

Glide avalanches are very difficult to predict. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

"Glide avalanches" occur when the entire snowpack(from ground to surface) slides slowly downslope. A large crack(called a "glide crack") is formed at the top of the slope, and below this crack is where the snow is slipping down the hill. The rate of glide is variable and based on many factors(not well understood). The two biggest influences are the ground cover(smooth grass and rock slab cause glide) as well as the amount of free water at the base of the snowpack which can lubricate the sliding surface. Often these glide slabs will slip downhill for months, or most of the winter. They are very unpredictable and when they decide to release then we generally get a very large avalanche because the entire snowpack depth to the ground slides. When the glide slab finally releases-that is a "glide avalanche. "[Reference : Grant Statham, Avalanche Specialist, Parks Canada. ]

OBS

Do not confuse "glide avalanche" with "full-depth avalanche". Glide is a slow process that usually occurs over several days, weeks or even months, while a "full-depth avalanche" is a sudden release of a slab avalanche that breaks to the ground.

OBS

glide avalanche; glide release; glide slab avalanche: terms officially approved by the Avalanche Bulletin Terminology Standardization Committee.

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Avalanche de neige très humide, surtout dans les régions de montagne sous influence maritime [...] où le glissement du manteau neigeux provoque une fissuration et, à plus ou moins longue échéance, une avalanche.

CONT

[...] dans une zone de reptation et dans un climat humide, des fissures du manteau neigeux peuvent se développer pendant de longues périodes (plusieurs jours) et être à l'origine d'avalanches [...] Ces avalanches de glissement sont des phénomènes rares dans les Alpes mais fréquents [...] dans les pays avec un climat océanique.

CONT

Il est difficile de prévoir les avalanches de glissement. [Exemple entériné par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.]

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

Meteor consisting of an ensemble of liquid or solid water particles falling through or suspended in the atmosphere, blown by the wind from the Earth's surface or deposited on objects on the ground or in the free air.

OBS

[Examples of hydrometeors.] Liquid or solid water formation that is suspended in the air includes clouds, fog, ice fog, and mist. Drizzle and rain are examples of liquid precipitation, while freezing drizzle and freezing rain are examples of freezing precipitation. Solid or frozen precipitation includes ice pellets, hail, snow, snow pellets, snow grains, and ice crystals. Water vapor that evaporates before reaching the ground is virga. Examples of liquid or solid water particles that are lifted off the earth’s surface by the wind includes drifting and blowing snow and blowing spray. Dew, frost, rime, and glaze are examples of liquid or solid water deposits on exposed objects.

CONT

Radioactive solid waste is monitored and segregated for consignment to various storage facilities based on radiation fields, and the type of radionuclides contained. Wastes containing significant quantities of radioactivity are stored in engineered facilities, most of which are concrete bunkers, with lined holes set into the ground being used for the water table in free draining sands. Wastes with lower radioactivity content are buried in trenches in the sand at Area c, with the trench bottom above the water table. LLRW received from offsite is similarly segregated and stored.

CONT

The Prince Edward Island Department of Community and Cultural Affairs, with assistance from Environment Canada, is planning a Household Hazardous Waste Collection Day to be held June 4, 1988. ... Wastes will be segregated; recyclable materials will be recovered; low hazard materials will be landfilled or burned; and hazardous wastes not amenable to on island disposal will be sent off site via a contracted licensed disposal firm.
