Hi, MT3D normally print out some messages in its standard output file before it stops. You may want to check if there is any error message at the very end of...
The Darcy's Law is applicable to all the ground water flow conditions. But K of filtration is a function of /velocity/: 1. for very slow flow 2. for very...
MODFLOW is not well-suited to modeling variably saturated flow. There is an add-on called SURFACT that can be used to model the unsaturated zone above a...

Probably not for a dam breach. The lack of ET and ground water seepage would also allow the model to me more conservative; which is preferable. Mark Schwartz,...
