MAYORGA LLERENA, Eduardo Patricio. Comportamiento iónico-pluvial en la cuenca del Cutuchi durante invierno y verano 2013. Figempa [online]. 2016, vol.1, n.1, pp.45-52. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v1i1.45.

The waters of the basin Cutuchi have a predominance bicarbonate by the geological past of the place; The aim of this study was to characterize the behavior of ionic water depending on rainfall during the winter and summer periods of 2013; The study was located at coordinates: UTM (WGS84) Zone 17S X: 766806; Y: 9,867,344. 16 samples in triplicate each / 8 days, in Phase I (January-March) and Phase II (July-August) were taken. They were analyzed: pH, EC, temperature, STD, Na+, K+, Ca2+, Mg2+, CO3 2-, HCO3 -, Cl-, SO4 2-, B, under APHA/AWWA/WEF. The waters are placed in categories C2 and C3 as salinity, EC / RASorg ratio determines water-S1 class C2 / C3 and C3-S1-S1en phases I and II respectively, leading to the conclusion that the waters of the basin contributing to the channel Cutuchi Salcedo Latacunga Ambato channel are at high risk of salinization. Similarly, it is concluded that water basin Cutuchi contain concentrations of ions corresponding to water Bicarbonate calcium and / or magnesium and due to the proportion of bicarbonates dependent changes in the level and intensity of rainfall generated both during summer and winter.

Palabras clave : salinity; sodium adsorption ratio; carbonates and bicarbonates.
