This paper illustrates the importance of sensitivity analysis in the design of clay barriers. Theoretical modelling simulations are performed using the finite element method in which realistic scenarios for unsaturated flow are conceived. Results show that the adjoint operator technique can be an efficient component to evaluate the impact of the thickness of the clay barriers as well as in the values of hydraulic conductivity values on pressure head distribution and integrated travel time.
