Hi,

I have a 2D vertical unsaturated flow slice model in which I am using 3rd type transfer boundary conditions to simulate transpiration from both the unsaturated and saturated zones. The model appears to be running fine, however when I run a budget analysis on the transfer nodes I get significantly different flux rates and water volumes (as high as two orders of magnitude) exiting the system for identical simulation runs. Does anyone have any thoughts on this? Could it be due to budget calculations for the unsaturated zone?

Any thoughts would be greatly appreciated.

Thanks
