This note describes a technique for obtaining uniform water content distributions in unsaturated laboratory soil columns. A predetermined amount of water is added to a column packed with air-dry soil. The column, placed in a microwave oven, is subjected to heating and cooling cycles, which rapidly redistribute the water inside the column, largely as a result of vapor phase transport. The method appears useful for preparing soil columns when measuring transport parameters in moist soils.
