Re: Boundary condition

Hello Jirka, Thank you very much for the response. I have tried the atmospheric boundary and variable flux at the lower boundary. I realised that the pressure head at the upper boundary was always increasing. How do I maintain the pressure head at upper boundary at 0 during wetting (i.e. saturation)...

Re: Boundary condition

Hi, I want to simulate drying and wetting cycles in a laboratory column experiment. The column is saturated by applying water from the lower boundary. The saturation is maintained for one week while allowing water to leave the column only by evaporation. After one week, flow at the lower boundary to...
