How does Hydrus calculate Fitted flux in inverse solution?

Hi,
How does Hydrus calculate Fitted flux in inverse solution? I can see all the flux values at each time and space in Hydrus 1D. However, I don't exactly know how Hydrus calculates the Fitted cumulative flux values from the space-time flux values?

Re: Oscillations in water content output with time

My name is Zana Taher. I am a Phd student at Colorado State University. I guess Hydrus 1D uses ∂^2 u/∂y^2 =0 for saturated condition based on the assumption that there is no volume change at saturation. However, in geotechnical engineering (and mining geotechnics), this assumption will not work. I a...

Richard's equation (PDE) for expansive soils

Hi, I am working on 1-D simulation of matric suction (negative pore water pressure) in unsaturated expansive soils using Richard's equation (similar to equation 2.1 in the Hydrus handout: HYDRUS1D-4.08). The difference in simulating matric suction of expansive soils versus non-expansive soils is tha...
