Water Table doesn't move after raining.

Please login with a confirmed email address before reporting spam

Hi all,

I am doing 2D modeling for the effect of contaminant infiltrating from the surface and then spreading over an around 30-m wide and 6-m depth area in a few years using COMSOL 4.0a, Earth Science Module. In my model there are 3 layers of soil and the bottom layer is a rock. So far I've coupled Richard's equation and Solute Transport equation in my model. However I got a problem; the modeling result shows that my groundwater table only fluctuates in the first 2 or 3 rainfalls; afterthat although there are significant rainfalls, the water table remains the same.

Can anyone help me?

Thank you,
Charles

Can anyone help me? I've still got stuck and can't proceed further with my model :(
