CALCULATING THE AMOUNT OF UNFROZEN WATER IN FROZEN GROUND FROM MOISTURE CHARACTERISTICS CURVES

THE UNFROZEN WATER CONTENT OF A SOIL CAN BE DETERMINED BY CALCULATING THE PARTIAL MOLAR FREE ENERGY OF WATER (DELTA F) AT ANY TEMPERATURE AND REFERRING THIS VALUE TO THE PLOT OF DELTA F VS. THE WATER CONTENT OF THE SOIL UNDER CONSIDERATION. A PLOT OF DELTA F VS. WATER CONTENT CAN BE OBTAINED FROM A MOISTURE CHARACTERISTICS CURVE AT ROOM TEMPERATURE. METHODS OF CALCULATING THE NUMERICAL VALUES FOR THE GRAPHS ARE OUTLINED. DATA ARE GIVEN FOR GRANULAR, CLAY, LOAM, AND PEAT SOILS AND FOR NA-MONTMORILLONITE, SO THAT THE RESULTS SHOULD BE USEFUL IN ESTIMATING UNFROZEN WATER BY COMPARING AN UNKNOWN SOIL WITH A SIMILAR SOIL IN THE REPORT. /AUTHOR/
