Abstract

This method covers determination of capillary-moisture relationships for fine-textured soils as indicated by the soil-moisture tension relations determined by pressure membrane apparatus using tensions between 1 and 15 atm. Moisture tension is defined as the equivalent negative gage pressure, or suction, in soil moisture. The test result is a moisture content which is a measure of the water retained in the soil subjected to a given soil-water tension (or at an approximately equivalent height above the water table).
