Knowledge of the mechanisms of water and solute transport in soils and other porous media is fundamentally important in many diverse fields, from agriculture, through hydrology and petroleum engineering, to environmental science. Better observation and measurement technology is a key component for achieving better knowledge. Techniques are needed that are reliable, robust, automated, and can be used across a wide range of spatial and temporal scales. Such techniques not only will improve our ability to manage soil and water resources, they are also a prerequisite for achieving advances in our fundamental understanding of water and solute transport through soils in both the laboratory and the field.
