The hydrology of our soils is controlled by the physical processes operating at the soil surface. We describe the new measurement techniques that are improving our vision of these processes. Tension infiltrometers can be used to determine the infiltration rate into soil and to measure the soil's near-saturated hydraulic properties. These properties reveal whether there is likely to be preferential, or bypass, flow through the soil. Tipping-bucket water flux meters can be used in the field at remote locations to provide a detailed temporal record, in real time, of the flow of water and transport of solutes moving through the surface soil. These observations, along with new modeling schemes, are increasing our ability to predict the hydrological functioning of surface soils.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
