Dispersion in Unsteady Porous-Media Flow
Study deals with manner in which originally sharp interface between 2 miscible liquids is altered as liquids undergo unsteady motion in porous medium; specifically, fresh water-salt water...

Longitudinal Dispersion in Steady and Unsteady Flow
Summary of results of experimental investigation concerning 1-dimensional dispersion in porous media under laminar flow conditions; in agreement with previous investigators, dispersion...

Depth and Spacing of the Drain Systems
Paper discusses saturation of agricultural soil by over-irrigation or rain; downward seepage flow through porous soil to system of parallel tile drains is studied, and theory of hydrodynamics...

Free Surface Flow in Homogeneous Porous Medium
Damping of unsteady flow through dam or levee with horizontal underdrain, when head behind it is raised considerably, is treated analytically and tested in Hele-Shaw model; slow and rapid...
