Field measurement of water and solute transport parameters in soils.

摘要: The transient and steady rate of infiltration water into soil reflects the arrangement particles aggregates resultant maze pore voids which conduct water. size, distribution continuity pores is reflected in changes both saturated hydraulic conductivity unsaturated components, flux potential sorptivity. These components can be measured field using well permeameters for subsurface measurements, pressure tension infiltrometers surface measurements. Note that infiltrometers, give more detailed information on properties, also used at depth if a pit dug. In this chapter we focus procedures Guelph permeameter its infiltrometer attachments.
