Measurement and interpretation of physical properties of soils

Creator:

Nagpal, Narender Kumar, 1942-

Abstract:

One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

The steady state flow of water through unsaturated soil in the low capillary potential region

Creator:

Stammers, William Norman

Abstract:

Several investigators have recently called attention to the fact that the flux equation for water movement in unsaturated soils may not be an appropriate mathematical model for the development of the theory of unsaturated flow phenomena. An analytical theory is developed for the purpose of testing the validity of the...

Variations of moisture retention properties and bulk densities of soils between and within soil-mapping units in central Oregon

Creator:

Jibury, Falih Khidir

Abstract:

The objective of this study was to estimate the bulk densities and points on the moisture-tension curves and to determine their associated variances for some of the selected mapping units in Central Oregon. These variances will produce informations concerning the precision of the mean and the optimum sampling schemes, for...
