  1. Hello !!!!! I am making a simulation of a tracer test with three injection wells (north) and one pumping well (south). On the injection wells we have injected the salt and water for 16 hours and then successively water for two months. After 16 hours of injection (the initial concentration was 330g/l), we started to pump almost the same amount of water injected on the north on the same time span. we have found the Kx values that match the arrival times of the breakthrough curve at the observation points, according to the pathlines. The problem is that I am getting Nacl concentrations that
  2. Hi everyone, I am currently doing a project regarding in-situ chemical oxidation of BTEX using persulfate solution, and trying to use RT3D to represent the process. As reading the literature the reaction should be a pseudo 1st-order kinetic reaction model, but the only relevant option I found in the reaction package is the inst. aerobic degradation of BTEX which only offers oxygen as the electron acceptor. In this case, could someone familiar with the persulfate or other similar oxidation mechanisms tell how to construct the RT3D model? convert the persulfate concentration to
  3. Just came up with a question regarding where to apply different solution schemes for the advection package activated in the MT3D or RT3D model, and the cases are based on the tutorials 1. Can someone please explain further why we choose the Standard finite difference method for both the Sequential anaerobic degradation and BTEX degradation with multiple electron acceptors, MMOC for the Rate-limited sorption reaction, MOC for both Instantaneous aerobic degradation and Double-Monod model, 3rd order TVD (ULTIMATE) for all MT3D tutorial cases, etc. If there were relevant recommended rea
