Abstract:

Methods for using tensiometers in conjunction with moisture retention characteristic curves for non-destructive soil water measurements are presented for above- and below-freezing situations of engineering interest. Four methods for determining moisture retention characteristics, three tensiometer types, and several methods of recording soil suction are discussed. Procedures for preparing, modifying and installing tensiometers for field use in cold climates are explained. Several examples of moisture retention characteristics are shown, including the effect of soil density on water retention. Examples of soil tension ahead of and behind a frozen soil zone are also presented. Author
