Assessing irrigation water quality in Faridpur district of Bangladesh using several indices and statistical approaches

Several water quality indices, i.e., salinity hazard (SH), sodium percentage (Na%), sodium adsorption ratio (SAR), permeability index (PI), magnesium hazard (MH), Kelly’s ratio (KR) and irrigation water quality (IWQ) indices are applied to assess the irrigation water quality using 60 groundwater samples collected from the study sites. This study reveals that groundwater samples are mainly.. Read More
