Dinámica espacio-temporal (2004-2017) en el parque ecológico Distrital de humedal Capellanía en Bogotá a partir de parámetros de calidad de agua

Based on the water quality data provided by the Bogota Water and Sewerage Agency (EAAB), Suspended Solids Contamination Index (ICOSUS), Eutrophication Index (ICOTRO), pH Index (ICOpH), Biological Oxygen Demand (DBO) and Total Coliforms Index were evaluated from 2004 to 2017 in Capellania Wetland. The values of these indexes diminished significantly, between the early years of study (2004-2006) and the late years (2014 and 2017). In addition to this, coverage transformation maps were made, and it was observed a greater urbanindustrial growth from 2004 to 2011, in comparison to 2011-2017. Together with the results of water quality, the transformation of afferent basin coverage does not seem to directly affect the water quality in the wetland. Also, EAAB strategies used for wetland maintenance and recovery were investigated, and a progress was observed between 2008 and 2017, which, according to the first objective, appears to have a positive effect on the water quality of the wetland. Finally, a principal component analysis and a Spearman correlation test were executed, and it was found that the variables of total colifomrs, DBO and phosphorus have a high-significantpositive correlation, suggesting the same sources of contamination.
