MODELING FIELD INFILTRATION INTO UNSATURATED CLAY

This paper examines the ability of a numerical model to match observed field behavior, for infiltration into an unsaturated clay. The exercise concentrated on the autumnal recharge of 1984. This involved the development of a numerical model, and material parameter identification was described based on experimental work on undisturbed clay samples. A method of applying the numerical model to the simulation is presented. The study concludes that the numerical simulation has proved capable of representing field behavior, over the depth of summer moisture deficity penetration. The results show that the overall approach adopted can be used in a predictive mode.
