Impacto de las actividades humanas en el transporte de sedimentos fluviales hacia los océanos : perspectiva desde el río Magdalena
(Universidad EAFIT, 2024) Vargas Gómez, Juliana; N/A
Anthropogenic activities increasingly exert greater control over the production, transport, and accumulation of sediments in river basins. The purpose of this research is to analyze the impact of human activities on sediment transport from rivers to oceans, focusing on the Magdalena River, Colombia’s most important river basin. Human activities have heightened sediment transport, especially in regions dominated by deforestation and agriculture, as seen in the Magdalena River. Globally, while reservoirs retain sediments and reduce transportation to coastal areas in some regions, in others, the impact of deforestation, agriculture, and mining increases the riverine sediment load. Studying variations in sediment transport is essential in the Anthropocene, an era in which human activity is the main agent of environmental change. The use of models like BQART enables estimation and prediction of changes in sediment transport, providing data for resource management and biodiversity conservation in affected areas. In conclusion, the results of this review highlight the need for public policies that mitigate human impact on river systems, promoting sustainable practices to protect both river and coastal ecosystems as well as water quality and at-risk habitats.
