Relaciones de caudal, conductividad eléctrica y concentración de cloruros, en diferentes sectores del Río Fucha a partir de la información histórica disponible en el periodo 2010 a 2021

Abstract

The following work studies the relationship that may exist between the flow and the physical-chemical parameters such as chlorides and electrical conductivity in different sections of the Fucha River; a comparison of historical data of water quality analysis and flows, carried out by government entities over a period of ten years is carried out; as well is done sampling and measurements in situ during the month of June 2021 in five sections of the river, defined as key monitoring points of the District Environment Secretary of the city of Bogotá. Once the measurements and analysis of the laboratory samples have been obtained, the calculations of the practical and theoretical flows, and the concentrations raised in the study, are established. A significant variation of the measured flows evidence since these exceeded the anthropic values calculated. From the research it is observed that, as progress is made along the monitoring points, a greater contribution of wastewater and rainwater is considered, having an increase in flows that correlates with the increase in conductivity and chlorides; However, the data and measurements were insufficient to be able to define if there is a direct relationship where by means of chlorides a flow measurement in wastewater can be obtained.
