Abstract

GUANANGA, Nelly et al. Influence of geomorphology and flow on the water quality of Guano river, Ecuador. Novasinergia [online]. 2022, vol.5, n.2, pp.174-192.  Epub July 05, 2022. ISSN 2631-2654.  https://doi.org/10.37135/ns.01.10.10.

The present study determines the water quality of the Guano River in Ecuador through the water quality indices WQI-NSF, WQI-Dinius, and a variant of the WQI-Dinius index that includes the average slope of the riverbed and the flow. To obtain qualitative values of water quality that allow better use of the river water. The results obtained with the three indices show that there is slight contamination in river sections caused by human activities, decreased flow, and wastewater discharge. Furthermore, the work shows that when applying the WQI-Dinius modified, the values of the weights of the water quality are lower concerning the other indices. But, even when the WQI-Dinius modified values are common, the valuation range for agricultural use is similar among the three indices, maintaining the criterion that the Guano River is slightly contaminated. Therefore, treating the water before using it in agricultural activities is necessary.
