Dear all,
I am using an inverse Mobile and Imobile water model in HYDRUS 1-D. I forced HYDRUS to calculate theta_r and theta_im.
Is there any relationship or correlation between these two? Should theta_r be less than theta_im? Indeed, they are two different concepts but not so sure about their relationship.
Thank you.
Best regards

Re: Immobile water content and residual water content
H1D does not consider any relationships or correlations between theta_r and theta_im. Theta_r does not have to be less than or equal theta_im. However, if theta_im is larger than theta_r, in transient simulations, you may encounter unphysical situations when theta_im is larger than theta (which would result in infinite fluxes). Thus, theta_im must be smaller than the smallest theta during the entire simulation. J.
