Resumen
The analysis of the hysteretic behavior in relation to the concentration/water level allows to
identify fluctuations in the concentrations of the water quality parameters depending on the
flow. The Machángara River basin is relevant because it is a source for drinking water
treatment, irrigation and hydroelectric generation. The present research aims to analyze the
hysteretic behavior of water quality parameters: turbidity, total solids, pH, BOD5, phosphates,
nitrites-nitrates, and total coliforms, located in an urban, peri-urban and conservation area of
the Machángara River sub-basin located in the Paute River basin, during the period 2006 -
2013. In this sub-basin, the influence of seasonality (dry-wet), land use, and vegetation cover
on the hysteretic behavior of each of the aforementioned parameters was evaluated. For the
elaboration of the hysteretic graphs, the water level was ordered chronologically along with
the value of the parameter, as well as the seasonality and hysteretic direction were also
represented. The results showed that the hysteretic behavior of turbidity is affected by the
heterogeneity of land use and vegetation cover and the pH due to moorland vegetation and
its contribution of organic material. Furthermore, seasonality influences the amplitude of the
hysteretic behavior of the parameter concentrations. Finally, the study made it possible to
identify that in conservation and urban areas the behavior tends to be counterclockwise, while
in the peri-urban area in most parameters there is no defined hysteretic behavior.
