PUT THE DISCHARGE XLSX FILES HERE
==================================

what goes in this folder: the "River Water Discharge" excel exports
from india-WRIS (indiawris.gov.in), one file per gauge station.

filenames MUST look like this (this is what WRIS gives you by default,
so just don't rename them):

    River Water Discharge_Arjunwad (seasonal).xlsx
    River Water Discharge_Kurundwad.xlsx

the part after the underscore is the station name. it has to EXACTLY
match the "station" column in stations.csv at the project root
(the "(seasonal)" part is ignored) AND match the matching water level
file in ../wse/ - same station, same spelling.

discharge data is used for VALIDATION (comparing the satellite-derived
discharge against what was actually measured). a station without a
discharge file still gets its water level validated, it just won't
show up in the discharge metrics.

do NOT put anything else in here. the pipeline only reads .xlsx/.xls
files from this folder. this README is ignored.

then run:  uv run python run_pipeline.py --steps 3-8
