River Storage_TESTCASE_HYMAP TOO HIGH

[Nguyentuong1770]

Dear LISF user Forum.

I run LIS test case with HyMAP2 option, but the output file shown the result of river storage too high, i attached here the output file.
I don't know it is normal.
Could you look at this file.
Any explanation will be appreciated.

Thank you.

Hi @Nguyentuong1770,
could you please provide more details on the simulation setup, specific output variable name and value range?

Dear Agetiran Augusto Getiran.

Very glad to hear from you.

The model time duration from may to october
I attached below the setting up files for your reference.

and the last month result file.

Best regard.

Hi @Nguyentuong1770,
please provide individual files, not ZIP files.

I need a more detailed description of your issue so I can help. What exact output variable are you referring to, what do you assume as a high value, what domain and resolution are you using? Is the simulation crashing?

Also, did you try to look at other output variables? Are they consistent?

Hi Agetiran,

Sorry for the Zip files posting, but be understand that some file's formatting did not allowed by the system to post.
For the detailed description of model and the exact output variables I have described in the individual files and images attached below.
The simulation did not crashed at the end with
the domain and resolution remained as in test case, as follow:
Map projection of the LIS domain: latlon
Run domain lower left lat: 34.375
Run domain lower left lon: -102.875
Run domain upper right lat: 39.625
Run domain upper right lon: -96.125
Run domain resolution (dx): 0.25
Run domain resolution (dy): 0.25

The result of river storage reached 15 million m3 in some points and i don't know it 'is normal?.

Kind regard.

Hi @Nguyentuong1770 ,
this is clear now. Considering your spatial resolution (0.25 deg), a river reach within a grid cell should have, on average, 25-30km (let's use 25,000m). Let's say it's a large river with 1000-meter width, and a few meters depth, say 2 meters. 25,000 x 1000 x 2 = 50 million m3. Your 15 million m3 seems reasonable.

Hi @agetiran,

Thank you for your clear explanation on this post.
It helped me to understand the issue.
