... we initiated a world-wide effort on collecting infiltration measurements and related soil properties. This database provides crucial information for soil parameterization and will make such data globally available. Since infiltration controls the partitioning of water that reaches the land surface in a fraction that is entering the soil profile and a fraction that generates overland flow or surface runoff, the accurate prediction of infiltration is of great importance for our modeling community, as it directly affects soil moisture and the partitioning of energy fluxes at the land surface (including feedback mechanisms between the land surface and the atmosphere).

Aim for the analysis of the database in this phase is developing pedotransfer functions to estimate parameters in infiltration equations (e.g. Philip equation but eventually also other equations and parametrizations) from infiltration experiments.
