Hi I need to calculate the salt/mass load (salt/mass load contribution of the groundwater contaminant plume to the stream/drain) in certain streams from my MT3DMS model. What is the best/easiest way to calculate it? My input units are in metres and mg/l. Do I select compute mass flux at sources/sinks in the Transport observation package menu? Then use the drain coverage to see what the mass flux is along the segment? What unit is this mass flux then in? mg/day ? mg per time step?
Hi Community, I am trying to run MT3D-USGS in a model which contains plenty of dry cells computed by mf2k5, but MT3D-USGS chrashes. The .out file reports that plenty of cells have "saturated thickness =0.0000" (i.e. they are dry), "not allowed in transport model" and furthers says "reset as incative". I have attempted to set some of the dry cells as inactive, but those cell still show up as erroneous in the output file. What am I missing, or what can I do to make MT3D-USGS work? - Niklas
Hello Dear friends, I use the latest version of GMS (10.3.1). And my goal is to model the movement of LNAPL (gasoline) with the MT3D-USGS model. At the beginning of modeling, I encountered with a problem. If friends are familiar with this model, guide me. Thanks
