Hydrochemical appraisal and solute acquisitions in Seti River Basin, Central Himalaya, Nepal.

The chemical characterization and assessment of the water quality in the headwater areas of the Himalaya are necessary for securing the water in the future. This study aims to assess the hydrochemistry and water quality concerning drinking and irrigational uses in the Seti River Basin (SRB), Nepal. A total of 45 water samples were collected in 2016 from the SRB during pre-monsoon, monsoon, and post-monsoon seasons, and pH, EC, TDS, and DO were measured on-site, whereas Ca, Mg, K, Na, Cl, SO, NO, and dissolved Si were analyzed in the laboratory.
