Deep Drainage Boundary condition

Hi I am using Hydrus to estimate groundwater recharge my soil profile is 60 cm and I have soil moisture sensors at 20 cm and 40 cm and I have a water table at 28 (mbgl). Would you please assist what do I insert in this Deep boundary condition window, especially the first two option. Please see the a...

Hi I am running the RETC with retention data only to obtain all the hydraulic soil properties needed by Hydrus. But when I look in the output file I only get alpha, n, Theta_r and Theta_s I understand that this is because I do not have hydraulic conductivity data but from the output file there is a ...
