A comprehensive method for improvement of water quality index (WQI) models for coastal water quality assessment

open access: yesWater Research, 2022
Here, we present an improved water quality index (WQI) model for assessment of coastal water quality using Cork Harbour, Ireland, as the case study. The model involves the usual four WQI components – selection of water quality indicators for inclusion, sub-indexing of indicator values, sub-index weighting and sub-index aggregation – with improvements ...
