DEF

Water artificially applied in the form of rain, usually by a rainfall simulator for experimental purposes.

CONT

In BRI's laboratory for building foundation and soils, full-scale testing for soil dynamics is performed. A large-scale, shear soil layer box (5 m x 4 m x 10 m) is equipped in five large pits 6 m below ground to reproduce vibration of the ground during an earthquake. A test for rainfall is conducted in this laboratory using an artificial rainfall apparatus with an intensity up to 150 mm/h that addresses soil pressure during rainfall. In the wind and rain test laboratory, experiments are conducted on the effects of wind on buildings, the waterproof performance of finishes, and the air-flow characteristics in and around buildings.

CONT

They exposed different Sphagnum species to artificial rain (pH 4.2) containing different concentrations of bisulphite or sulphate, within the limits of very high values encountered in some samples of rain.

OBS
