This paper investigates the interaction between soil and atmosphere in pyroclastic soils with a view to understanding the influence of meteorological factors on soil variables (essentially water content and suction). Such factors are known to have a great effect upon slope stability. As our particular interest lies in the influence of evaporation, we set up a physical model to quantify evaporation fluxes and use the results to interpret fluctuations in soil water content and suction. The physical model consists of a 1 m3 tank filled in this case with pyroclastic soil and exposed to natural weather elements. The system is extensively monitored to record atmospheric and soil variables during the tests.

Abstract
This paper investigates the interaction between soil and atmosphere in pyroclastic soils with a view to understanding the influence of meteorological factors on soil variables (essentially water content and suction). Such factors are known to have a great effect upon slope stability. As our particular interest lies in the influence of evaporation, we set up a physical model to quantify evaporation fluxes and use the results to interpret fluctuations in soil water content and suction. The physical model consists of a 1 m3 tank filled in this case with pyroclastic soil and exposed to natural weather elements. The system is extensively monitored to record atmospheric and soil variables during the tests.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
