Please let us know when the CLN Package in MODFLOW-USG will be available in GMS. I have many projects that I could use this on. One is just starting up, with 2-3 starting later this year. The other request I have is for GMS to develop a scheme to allow for Time Varient Material Properties. I understand that MODFLOW does not allow for TVM properties, but it seems like there could be a sub routine that the GUI could implement to make it significantly easier to model projects where the aquifer properties are altered.
