The water storage capacity in the unsaturated root zone of soils is the principal source of nonlinearity in the response of terrestrial hydrological systems. This storage capacity between field capacity and the permanent wilting point represents the water volume required by and accessible to vegetation to ensure continuous access to water to bridge dry periods. With detailed data on root depth distributions and soil porosities, this volume can be estimated. However, while such data may be available for individual plants or for small forest stands at experimental sites, they remain problematic to acquire at an adequate spatial resolution for scales larger than that,let alone for entire catchments or river basins.
