Help on large river stage gradients and GHB boundary head gradients warnings

[Zena Tessema]

Hello everyone,

I am currently working on a SWAT-MODFLOW simulation for my project.

During the MODFLOW run (using MODFLOW-NWT), I encountered warnings related to large river stage gradients and GHB boundary head gradients.

Could anyone please advise on how I can resolve these issues?

I have attached a screenshot for additional context.

I would greatly appreciate any guidance or suggestions you can provide.

Best regards,
