Hi, @wwieder
I've been working on the hydrology cycle and nitrogen cycle recently and have some questions on the water flux and nitrogen cycle. In CLM's hydrological modules, I saw it evaluates the surface water runoff and water drainage(sub-surface runoff) at the whole column level, and it makes sense to use these two fluxes to evaluate the nitrogen loss at the surface and sub-surface. But, there is another module that calculates the water diffusion between different depths called soilwater_zengdecker2009 in SoilWaterMovementMod.F90. Is this different with the sub-surface water runoff mentioned before, and which one is the real water drainage?
If I understand correctly, the SoilWaterMovementMod.F90 calculates the fast aqueous water transport vertically, can we attach the soluble inorganic nitrogen to this flux to evaluate the vertical transport of nitrogen/carbon? CLM hasn't been done yet, any considerations behind this, or if we apply the vertical fast aqueous transport of nitrogen in CLM, what would that happen? Thank you so much,
Best,
Jinmu
