Estudio de la Microcuenca del Río Cunuyacu en Función de la Cantidad, Calidad y Aprovechamiento Hídrico de sus Afluentes.

Abstract

"In the micro Cunuyacu River located south - east ofthe Province of Tungurahua, in the months from July to November 2010 was conducted to determine water quality and quantit in order to determine the infuence caused by human activi (agriculture Livestock, etc.) on this resource.

This was established for 5 monitoring points including point control. For quality assessment was used quality indicators WOI, EPT and BMWP / Col Roldal 2003 and the capacity to float method for the determination offlows.

The results show that water quality is poor (<21.43%), value resulting from the use of EPT rate does not apply to this ficoralttude, however, as values and BMWP WAI rates vary as folows: control point “and point 2 as the index WQI quality is good (> 76.95%) and of dubious quality to Criicism (40.8% - 31.2%) according to the index BMWP. In paragraphs 3 and 4 where there is great pressure of water quality as measured by the WOI is MEDIUM (<67.7%) and Crítcism (17.25%) according to the index BMWP. Ending point 5 where the quality as measured by the WI is good (72.66%) and of dubious quality (37.6%) according to the index BMWP.

In conclusion, the watershed is a good system of self natural purification of water qual, but presents a high risk to keep the minimum water system for conservation (86.74%shortage rate)."
