Abstract: Bhutan has an extensive river system that is generally distinguished by main rivers that flow north to south. The main rivers are Amochhu,Wangchhu, Punatsangchhu,and Manas. Manas is made up of Mangdechhu and Dragmechhu. For the purpose of management, Mangdechhu and Drangmechhu shall be considered as two separate basins. Amochhu and Drangmechhu originates in China.There are smaller rivers namely, Jaldakha, Aiechhu, Nyera-Amari, Jomori and Merak-Sakteng.

Process step:
Process description: Downloaded HydroRivers and HydroBASINS from HydroSHEDS (https://www.hydrosheds.org/) and loaded the HydroRivers and HydroBASINS level 8 data on the R statistical program. Loaded the Bhutan Map, and extracted all the rivers and basins entering and exiting Bhutan. Subsequently, the the rivers and basins entering Bhutan, and rivers and basins within Bhutan were delineated into 5 major hydrological basins (Amochhu, Wangchhu, Punatsangchhu, Mangdechhu and Drangmechhu) and 5 smaller hydrological basins (Jaldakha, Aiechhu, Nyera Amari, Jomori and Merak-Sakteng) following the delineation of river basins for IWRM planning and management as per National Integrated Water Resources Plan (NEC and ADB, 2016). Then in QGIS and ArcGis Pro, the basin boundary was adjusted in accordance with the international boundary map of Bhutan and basins delineated for the National Integrated Water Resources Plan (NEC and ADB, 2016)
