Questions about ModeMuse/ MT3D USGS

[Gabriella Menezes]

Hello everyone,

I’m getting started with groundwater modeling and I’m having some difficulties with ModelMuse. I would really appreciate any help or guidance.

1. How can I assign a river hydraulic head that varies with distance?

   I’m looking for a way to make the river stage change spatially along the river boundary, but I’m not sure which tool or approach in ModelMuse is best for that.

2. I’m also having trouble with MT3D-USGS.

   The model is not generating the .ucn concentration file, and I haven’t been able to understand why. Has anyone faced this issue or knows what typically causes the .ucn file not to be written?

Any help or suggestions would be greatly appreciated!

Thank you in advance
