摘要

Only about 3 % of the water on Earth is fresh water and more than two thirds of it is present as frozen water in polar ice caps and in glaciers. The remaining freshwater is mainly found as sub-surface water and is a major, yet not infinite, water resource on Earth. Sub-surface water is found in the pore space of rocks and soil and the movement of water and dissolved species through these porous media has a large impact on the environment. Understanding the flow and transport processes is essential in managing, utilizing and protecting the natural sub-surface water reservoir. The porous media containing sub-surface water are variably saturated covering the whole range from full saturation to partially saturated soils. In unsaturated porous media water is present both as capillary water in small pores, as liquid films on mineral surfaces and as capillary bridges in corners of angular pores and in crevices. Surface forces strongly affect the properties of confined water. Transport properties of confined water in variably saturated porous media at different length scales are discussed in the various contributions to part Ⅰ of this book. Here, we consider additional influences on the transport properties of water in porous media caused by dissolved species.
