In reviewing the output files (Hydrus 1d) for solute transport, I am trying to calculated strictly the cumulative mass of an organic solute arriving at the lower model boundary (in my case, the water table). Looking in the solute output file, I see the Sum (cvbot) [M/L2] - how do I go about correcti...

I am afraid that I have a bit of confusion regarding the alpha parameter in Rosetta. I am trying to perform a sensitivity to perturbing alpha paramters in my model. I have found a table that list the average value and one standard deviation (reported in parantheses) in Rosetta. The values are report...

Simple Hydrus-1D Obs Pt. Question

I am certain there is a likely simple solution to my question, but I have yet to discover it. I have a large unsaturated column, through which I am running a variety of pesticide transport simulations. I have inserted 10 observation points using the graphical interface and the model performed with n...

How is it that Hydrus reads the new "in" file? In editing the atmosph.in file, I have created a simulation that exceeds the graphical interface, however, Hydrus still rewrites the input file to emulate what was originally in the graphical interface, and not what I had edited in the text file. Sugges...
