KeywordsSoil moisture, Soil moisture instruments, Water supply forecasting - soil moisture

The several known instruments and procedures for measuring the moisture in the soil under a blanket of snow are taken up in detail with discussion. Neutron scattering; resistance method with porous blocks; capacitance method; Colman blocks; fiberglass and monel metal with temperature cell; thermal radiation units; gravity sample method; air humidity; heat conductivity; tensiometers. The procedure in which this soil priming factor is used in water supply forecasting is explained, as one of the important variables for the regression or correction to snow survey or precipitation data.
