Estudio de los sólidos suspendidos en el agua del río Tabacay y su vinculación con la cobertura vegetal y usos del suelo en la microcuenca

Abstract

The Tabacay river basin due to the different land uses and vegetation cover provides a wide range of values of surface runoff and sediment concentration, which significantly affects the uses of water, such as that destined for human consumption and, to the applications Later, as in the Paute Hydroelectric, as it causes a gradual degeneration of the turbines and sedimentation in the reservoir, causing hydraulic alterations. This research work is focused on the study of the solids in suspension that are produced in the microbasin, to link it later with the coverage and land uses. A monitoring program is designed in the river that contemplates both the analysis of the solids suspended in the water, as well as the characteristics of the bottom bed to analyze the sedimented solids. The monitoring also includes the measurement of the flow at each sampling point, an important data to determine the transport load; the measurement of the flow is made using the Float method, this, due to the difficulty of mobilizing measuring equipment that provides more accuracy. The monitoring campaigns will be carried out in constant intervals of time, probably achieving the most representative rainfall events of the micro-basin in the period May-July 2017. At the end of the investigation, control measures and pollution prevention are suggested. With these results, a management tool, useful in its decision-making process, will be delivered to the companies in charge of Surface Water control.
