Questions Regarding WRF-Hydro 5.4.0 Standalone Version and Output Analysis

[msvramana]

Dear Users,

I hope this message finds you well.

I have recently installed the WRF-Hydro Standalone version 5.4.0 successfully and completed the test case over the Croton, New York domain, following the instructions provided in the official test case documentation and user manual. The model ran successfully without errors.

However, after running the test case, I was unable to locate the surface runoff variable in any of the output files. To further analyze the outputs, I attempted to use Python for reading and visualizing the data. During this process, I encountered some challenges, such as:

• Converting UTM coordinates to geographic coordinates,

• Plotting inundation maps and other variables properly.

I would appreciate your support with the following questions:

1. How can I obtain the surface runoff variable? Is there a specific option in the namelist or another relevant output variable that represents it?

2. Are there any free tools or plugins (e.g., for ArcGIS, QGIS, or Python) recommended for working with WRF-Hydro 5.4.0 output data?

3. Is there a comprehensive user manual or guide for the Standalone WRF-Hydro model, similar to what is available for WRF atmospheric modeling?

Additionally, could you kindly let me know:

• Is there a standard procedure or tool for post-processing and visualization of WRF-Hydro output data?

• Are there any recommended tutorials or example workflows for Python-based analysis of WRF-Hydro results?

Thank you in advance for your guidance and support.

Regards,

MSV
