Evaluación del estado trófico de la Laguna de Colta utilizando imágenes sentinel-2 y análisis de laboratorio en el cantón Colta provincia de Chimborazo

Abstract

The purpose of this research was the trophic study of Colta lagoon in the province of Chimborazo, whose intention was to address an environmental problem such as eutrophication, caused by human activities and the proliferation of aquatic plants, which impact the quality of the water and biodiversity of ecosystems. The objectives were to jointly evaluate the situation of the lagoon, monitor its physicochemical parameters and develop models for analysis through Sentinel-2 Images. Regarding the methodology, field sampling, laboratory analysis and satellite image processing were organized in three stages. Both physical and chemical water data were collected at six sampling points, followed by image processing with three different processors to generate models of physical parameters of the analyzed water. It should be noted that the results revealed significant problems, such as high turbidity, contamination by suspended solids and a eutrophic condition due to the presence of nutrients. It is concluded that emphasizing the urgency of implementing environmental conservation measures to protect Colta Lagoon as a vital water resource. Therefore, the control of the proliferation of aquatic plants and the removal of sediments were recommended as priority actions. In summary, the study provided a comprehensive understanding of the trophic state of the lagoon, highlighting the importance of its preservation for biodiversity and local water supply, allowing the implementation of a sustainable management program for natural resources in the region.
