Water retention and transfer properties of a Green roof volcanic substrate

Autor: Pierre Delage, Filip Stanic, Emmanuel De Laure, Yu-Jun Cui

Publikováno v: E3S Web of Conferences, Vol 195, p 03011 (2020)

The water retention curve and the hydraulic conductivity function of a volcanic coarse granular material used as a substrate in an urban green roof in the Paris area was carried out on a newly developed device, in which low suctions were controlled.
