NARX-based water quality index model of Air Busuk River using chemical parameter measurements

<p>Water quality plays a major role in issues related to public health and marine life. Hence, monitoring river for contaminations is vital ensuring safe sustainable water resources. Conventional method assessing index costly as it requires considerable amount of time laboratory Therefore, this study proposes model based on artificial neural network. A six-year data Air Busuk River obtained from the Department Environment. Dissolved oxygen, biological oxygen demand, ammoniacal nitrogen has shown high correlation with index. The then developed these parameters, employing non-linear autoregressive exogeneous input structure. Generally, which three chemical parameters satisfactory performance overall regression 0.8767 passed function tests. offers potentially efficient cost-saving benefits government agencies authorities.</p>
