I started to work on this research project on my own and bit poking from my mate Arpita Mondal somewhere around 2020. I published this blog after having my first Choropleth in LinkedIn to share infantile joy with my peers.

Notes:

• Catchment delineation was done using SRTM ~30 m resolution DEM.

• Location of the Gauge-discharge sites were marked using miscellaneous information available at various sites of Government of Nepal, Government of Bihar etc.

• GIS Platform: ArcMap Desktop v 9.3.

• Sen's slope: Theory etc. may be found here and the cited by thingy with Google Scholar.
