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 hot 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 considerable spreading of the oil during thaw. The flow regimes by which oil permeates into snow and the clean-up implications are discussed. /// Les auteurs décrivent des recherches de terrain et de laboratoire sur le comportement de coulées isothermes et chaudes de pétrole sur la neige. A 0° C, le brut d'Alberta répandu est facilement absorbé par la neige et contamine une surface d'environ 0.01 mètre carré par litre. Un épanchement de pétrole chaud fait fondre la neige et se répand à la surface même du sol pour contaminer une surface d'environ 0.024 mètre carré par litre. Au dégel, la tache de pétrole peut se répandre considérablement. On discute aussi des régimes d'écoulement selon lesquels le pétrole imprègne la neige, et des implications sur le nettoyage. /// Описывается полевое и лабораторное изучение поведения пролитой на снег изотермической и горячей нефти. Сырая нефть Альберты, пролитая при О·С, немедленно абсорбируется снегом и загрязняет поверхность приблизительно равную 0,01 кв. м на один литр. Пролитая горячая нефть проделывает в снегу канал и течет под снегом по земле, загрязняя поверхность приблизительно равную 0,024 кв. м на один литр. Значительное растекание нефти может происходить во время оттепели. Обсуждаются характер проникновения нефти в снег и очистительные операции.
