Thesis ; no. 345 A thesis submitted in partial fulfillment of the requirements for the Degree of master of Engineering of the Asian Institute of Technology, Bangkok, Thailand. Thesis (M.Eng.) - Asian Institute of Technology, 1971 The bubbling pressure of a porous medium is defined as the capillary pressure at which the non-wetting fluid is first continuous through the medium. It is very important soil parameter in characterizing a partially saturated flow. The purpose of this thesis is to study the effects of pertinent soil parameters and fluid properties on the bubbling pressure. A capillary tube model analogy was employed to develop an equation representing the bubbling pressure as a function of soil parameters and properties of fluid. The soil parameters being con sidered were porosity, characteristic diameter of soil particle, and a coefficient which is a function of the pore size distribution index. The fluid properties were surface tension and specific weight. Experiments ~'7cre conducted to verify the theoretical equation and determine tile coefficient. The media \·rnre selected to hav-e wide ranges of texture, porosity, grain size distrioution and pore size distribution. The wetting fluid used was distilled water and non wetting fluid was air, Soil permeability Porous materials Arbhabhirama Anat, Chairperson Ackermann, Norbert L., Examination Committee Niwat Daranandana, Examination Committee Asian Institute of Technology, Scholarship donor Asian Institute of Technology.
