2D cross-section reactive transport

Recommended Posts


Is it possible to model reactive transport in 2d crossection in GWB (y is my vertical axis)? Should a direction of gravity vector be specified somewhere? I was looking into GWB Reaction transport guide, but I didn't find the answer. Thanks!

Hi Michal,


X2t uses hydraulic potential instead of pressure, so you don't need to specify the direction of gravity. You can use X2t for modeling a vertical cross section as long as there are no sharp density differences in the fluid. If there are large density differences and you need to account for buoyant forces, then you should use an imported flow field. You should look into section 4.3 - 4.5 of the GWB Reactive Transport Modeling Guide for more info.
