Dear Jirka,

Thank you so much for your reply ^.^

Have a good day~

Dear Jirka, I have one question not directly regards to HYDRUS 1-D. But I am using HYDRUS 1-D for inversely fitting model using Mobile-Immobile water model to obtain several parameters and aimed to calculate the retardation factor of solute. I crossed several manuscripts and found that we can calcul...

Dear Jirka,

Thank you so much for your quick and helpful response. It does help me a lot.

Have a good day!

Best regards,

Dear Jirka, Thank you for your reply. It is very helpful. Can I have one more question please? Under such condition, when we consider the Freundlich absorption, there is a term of "Fraction of sorption site in contact with mobile zone" - known as f. I crossed several papers, some assumes that as the...

Dear Jirka, I crossed by this post. and have one question please? "In the system with macropores, the dual-porosity model (which requires two domains – mobile and immobile) likely interprets the entire matrix as being immobile, since the flow is dominated by macropores." You stated this. Could you e...

Dear sir, Thank you so much for your quick response. I got it now. I have one more question, please. The Dual-Permeability Model with the two-site sorption model is inactivated in my HYDRUS 1-D version (which I downloaded from PC-progress website). Could you tell me how to activate it or which versi...

Dear Sirs, I have two questions regarding to Chemical and Physical Nonequilibrium Models in HYDRUS 1-D. Currently, I only see the Dual-Porosity Model with two-site sorption in the Mobile zone in the HYDRUS 1-D version that I am using. The "Modeling Nonequilibrium Flow and Transport Processes using H...

Dear all, My study is about the transport of As(V) through the vadose zone. I conducted the tracer test (with Cl-) and found that the two-region physical nonequilibrium model fitted well. Normally people used the equilibrium model for the tracer test and then use fitted v and D for modeling reactive...
