`add_sub_watershed.bat`: tool to resegment the model

[rburghol]

Todo:

• [ ] port to p532
• [ ] Final documentation

Overview:

• Run the script to use vahydro to get subshed data and resegment a downstream location
  • Use: ./run/resegment/add_sub_watershed.bat [subshed hydrocode] [downstream rseg] cbp-6.0 subsheds [da]
  • will add seg linkage
  • reproportion land use,
  • copy parameters
  • copy WDMs
  • create model in vahydro
  • set new river segment id as property in vahydro
• If resegmenting in a tidal segment, it will fail when it gets to the end of the script where it copies riverine hydro parameters. (see details here: https://github.com/HARPgroup/HARParchive/issues/747)
  • it fails, run the script copy_ad_hy_sc separately (called by add_sub_watershed.bat) with a different watershed as template for parameters.
  • Ex:
    • ./run/resegment/add_sub_watershed.bat YL0_7010_0000_beaverdam YL0_7010_0000 cbp-6.1 subsheds 17.57
    • After error, run: `./run/resegment/copy_ad_hy_sc YL0_7012_7010 YL2_6580_0001 cbp-6.1 subsheds
    • which copies from a different template YL2_6580_0001
• Re-Doing is often needed, if you get the drainage area wrong, or need to change the target for alternative downstream riverine parameters, or if the script was updated and you need new things.
  • You must use the new hydrocode (minus the vahydrosw_wshed prefix) when calling the script.
  • Ex:
    • First time I called: ./run/resegment/add_sub_watershed.bat JB0_7050_0000_little_creek JB0_7050_0000 cbp-6.1 subsheds 5.098 JB0_7052_0001 blank
    • Next time called: ./run/resegment/add_sub_watershed.bat JB0_7056_7050 JB0_7050_0000 cbp-6.1 subsheds 5.098 JB0_7052_0001 blank
