PUT THE WATER LEVEL XLSX FILES HERE
====================================

what goes in this folder: the "River Water Level" 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 Level_Arjunwad (seasonal).xlsx
    River Water Level_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, don't worry about it).

for every file you add here:
  1. also add the station's lat/lon to stations.csv (get the exact
     coordinates from the station's page on WRIS - wrong coordinates =
     the pipeline matches the wrong river = garbage results)
  2. if you have discharge data for it too, put that file in
     ../discharge/

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
