Odd Water Table Elevation Results

[Melvin Raymund Dangin]

Dear Dr. Seonggyu and group,

I got some odd results from my QSWATMOD simulation (Figure 1). The ground surface elevation at this point is only 16.84 masl. My modflow simulation results with modelmuse (Figure 2) is not too far from the observed, which used EVT and RCH from the same SWAT model used in QSWATMOD. Do you have any idea to what's causing this? 

The settings for my headtol, fluxtol, and maxiter are 0.001, 100, and 1000, respectively. Lower values do not reach convergence. You may access my model here for review:

Thank you very much for your time and guidance.

Sincerely.

Melvin

Good evening everyone, I too get strange results in QSWATMOD, with loads over 100m when in reality they should be just a few metres (2 - 3m). How did you solve this case?

Hi,

There are many factors that could contribute to high groundwater levels, including issues with model structure or parameters. Please share your MODFLOW model settings and parameter values.

Best,

Seonggyu
