Classification of water quality using artificial neural network

Deterioration in water quality has triggered many countries to initiate serious mitigation efforts because it is essential to prevent and control water quality pollution and to implement regular monitoring programmes to preserve the environment. Hence, the water quality index (WQI) developed b...

Based on the average WQI values of 35 stations for each river, it is shown that Pontian Kecil and Batu Pahat river were categorised in class III with WQI values of 71.2 and 71.5 respectively.
