The Behaviour of Crude Oil Spilled on Snow
ABSTRACT. Field and laboratory studies of the behaviour of isothermal and hot oil spills on snow are described. Alberta crude oil spilled at 0°C is readily absorbed by snow and contaminates an area of about 0.01 square metres per litre. A bot oil spill melts a channel in the snow and flows along the...

| Summary: | ABSTRACT. Field and laboratory studies of the behaviour of isothermal and hot oil spills on snow are described. Alberta crude oil spilled at 0°C is readily absorbed by snow and contaminates an area of about 0.01 square metres per litre. A bot oil spill melts a channel in the snow and flows along the ground under the snow contaminating an area of about 0.024 square metres per litre. There may be con-siderable spreading of the oil during thaw. The flow regimes by which oil permeates into snow and the clean-up implications are discussed. RhUMfi. Comportement du pdtrole brut rkpandu sur la neige. Les auteurs dkrivent des recherches de terrain et de laboratoire sur le comportement de coulCes isothermes et chaudes de pttrole sur la neige. A O°C, le brut d'Alberta r6pandu est facilement absorb6 par la neige et contamine une surface d'environ 0.01 m&re carr6 par litre. Un 6panchement de pttrole chaud fait fondre la neige et se dpand la surface m2me du sol pour contaminer une surface d'environ 0.024 mi3tre carrd par litre. Au &gel, la tache de &&ole peut se r6pandre consid6rablement. On discute aussi des r6gimes d'boulement selon lesquels le $&ole imprhgne la neige, et des implica-tions sur le nettoyage. |
