MEASUREMENT AND NUMERICAL ANALYSIS FOR INFILTRATION AND EVAPORATION BEHAVIOUR IN UNSATURATED SOIL

Abstract

It is known that infiltration and evaporation are the essential part of the hydrological cycle. The study of infiltration and evaporation behaviour in unsaturated soil can be conducted using several methods. This paper presents the analysis of a study on infiltration and evaporation behaviour in unsaturated soil from field measurement results.  A numerical simulation for the phase change of the pore water due to the change in temperature and pressure was carried out to obtain the infiltration and evaporation behaviour in unsaturated soil during rainy and no-rainy days. The numerical simulation results were then compared to the field measurement results.
