I'm aware of Hydrus and Netpath, but are there others? I am highly interested in water stable isotopes in variably saturated and non-equilibrium flow (double porosity/permeability). Any hints...

I apologize if this question has been posed before (if this is the case, please send me the link). It seems reasonable since precipitation is a point event and groundwater level record is a time...

I'd like to express the concentration of silver thiourea in aqueous solution [Ag(TU)n]+1 in terms of cmolc.L-1. The protocols for soil CTC using AgTU consider the mass of Ag for calculations and...

The most widely used parameter for biogeochemical modelling of radionuclides in soils is arguably the Kd. The use of some sort of Kd (e.g. kinetic, parameterized, one-point-Kd) is only possible...
