Water content smaller than residual water content

Hello I have a problem where the water content value in a single node (at the surface of a soil profile) at the final time of the simulation is smaller than the residual water content. I am simulating single porosity water flow, with root uptake. theta_r=0.032, and the water content at the surface a...

Re: Tracer breakthrough late arrival

Thank you Jirka Does the latest version of Hydrus 1D include the Ross and Smettem (2000) non equilibrium model? Is the Van Genuchten single porosity model considered an equilibrium or a non-equilibrium model? Quoting from your 2003 paper in the ‘Non-equilibrium flow and transport models\Single-poros...

Tracer breakthrough late arrival

Hello I am having a problem simulating tracer transport in unsaturated soil, in comparison to experimental data. The simulated breakthrough curve arrives much later than the measured curve, while for the same boundary conditions and hydraulic parameters, the simulated water content changes correspon...
