Re: Wrong concentrations solute transport

Sorry, some more information: I have made a model (800 cm x 235 cm) with on top a Atmospheric boundary condition (precipitation and evaporation), no flux boundary on the sites, a constant head at the bottom of the model with the constant head on drain level (at - 80 cm - surface level) and a seepage...

Re: Wrong concentrations solute transport

Thanks a lot for the helpful information, I solved the problem. I have a different problem now regarding the units of solute transport: I set a solute concentration of 2 ug/cm3 at Cvalue1 at the third day of the model, the solute concentration takes a day. If I open, from the results, the text file ...

Wrong concentrations solute transport

Dear, I am trying to simulate pesticide transport: from the moment the pesticides are contributed to the land, till the outflow of the pesticides through drains. I have made a model (800 cm x 235 cm) with on top a Atmospheric boundary condition (precipitation and evaporation), no flux boundary on th...

Re: infiltration concentration and variable head

Hello, I have a question on the time-variable boundary conditions for solute fluxes (i.e. cValue1, cValue2 and cValue3). I am trying to simulate pesticide transport: from the moment the pesticides are contributed to the land, till the outflow of the pesticides through drains. I have made a model wit...
