Abstract


Nutrient enrichment in aquatic ecosystems takes place due to multiple natural and human factors. The accumulation of nutrients in bodies of water can lead to undesired consequences for water quality. Considering that there is limited information on nutrients in tropical aquatic ecosystems, especially in Colombia, it is important to carry out research projects aimed at the conservation and proper management of water resources. In this context, a study of the spatial and temporal changes in nutrient loads into the Amaní reservoir (Magdalena River mid-basin, Colombia) was carried out considering interbasin water transfers from the Guarinó River to the La Miel River. In order to compare the trophic status in the reservoir before and after transfer operations have begun, simple eutrophication models were implemented.
