Horizontal infiltration experiments were performed to validate a plug flow model that minimizes the number of parameters that must be measured. Water and silicone oil at three different viscosities were infiltrated into glass beads, desert alluvium, and silica powder. Experiments were also performed with negative inlet heads on air-dried silica powder, and with water and oil infiltrating into i...

A recent airborne gamma radiation survey in the Los Angeles region, California, shows a moderate range in the levels of natural radioactivity. The lower levels can be related to lowland alluvium and the higher levels can be related to consolidated rocks. The highest radioactivity is associated with granitic intrusions and Tertiary volcanic rocks. The survey is nearly 2800 square miles in area a...

this paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. to this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. the g...
