Soil hydraulic functions of international soils measured with the Extended Evaporation Method (EEM) and the HYPROP device

Abstract

The paper presents a database of 173 soil hydrological data (raw data) from 71 sites all over the world (Asia, Africa, Australia America and Europe). The undisturbed samples were mainly collected and measured as part of research projects. The soils cover a wide range of texture classes and dry bulk densities. The database consists of water retention and unsaturated hydraulic conductivity data. Additional data like the particle size distribution, the dry bulk density, the organic matter content and other variables are included. Until 2007 the common evaporation method was applied. Since 2008 the hydraulic data were measured with the Extended Evaporation Method (EEM) and the HYPROP device in the range between saturation and close to the permanent wilting point, defined at pF 4.2. Information to the geo reference, the soil type, the sampling depth and the horizon are given. Data access: http://dx.doi.org/10.4228/ZALF.2003.273.
