HYBRAS gathers water retention data in a wide suction range (0-15000 cm) of Brazilian soils - open access

HYBRAS - Hydrophysical Database for Brazilian Soils

Collaborators: Department of Hydrology of the Geological Service of Brazil / CPRM, supported by the Federal University of Rio de Janeiro/Brazil, the Federal University of São Carlos/Brazil and international researchers.

HYBRAS gathers water retention data in a wide suction range (0-15000 cm) of Brazilian soils, all measured in undisturbed samples, as well as saturated hydraulic conductivity, granulometric fractions, particle density and bulk density and carbon content data with information of the sites from where the soil samples were obtained. The methodology for determining these soil properties is also available in HYBRAS. It is envisaged in the future to include in HYBRAS unsaturated hydraulic conductivity data!

The Geological Survey of Brazil, in partnership with other research institutions, is developing several pedotransfer functions of hydraulic properties in the Brazilian territory so that they can be used as input data in Brazilian soil modeling studies.
