Just finished the 2020 workshop, and I’m practicing the users’ guide example “weathering.x1t.” I’m trying to simulate the weathering in a soil profile under various precipitation (rainfall) conditions. Here is my conceptual model: (1) The soil profile is 1cm * 1cm * 300cm. (2) The porosity of the soil profile is 45% and the water content is 25%. (3) The water infiltration rate is 0.3m/yr. (4) The annual rainfall is 600 mm/year. (5) The simulation time is 20000 years. (6) temperature is 13℃ So far, the software settings are like the attached file. I am not sure whether the software settings match my conceptual model mentioned above. Also, what does it mean if the “reactant times” was set to be “1” in this software settings? Thanks for any response or suggestions. Appreciated. loess weathering 10-interglacial.x1t
