Abstract : The movement of water and Br was measured in unsaturated and partially frozen soil columns subjected to linear temperature fields. Both water and Br moved from the warmer to cooler parts in the columns. The data were analyzed under the assumption that Br is confined to unfrozen water. It was found that the negative adsorption of Br by clay surfaces plays a significant role in the transport of Br in frozen Morin clay and that Br tends to move faster than unfrozen water. jg
