Resumen

La cuenca del río Magdalena tiene una producción de sedimentos de 689 ± 528 t km -2 a -1 con valores máximos por encima de 2000 t km -2 a -1 . Análisis de regresión múltiple indican que los principales parámetros que explican la varianza en la producción de sedimentos de la cuenca son la escorrentía y el caudal máximo. Para describir la producción de sedimentos se obtuvo un modelo numérico con una eficiencia del 58% (P< 0.01) y un error cuadrático medio relativo (ECMR) del 11%. Los análisis de series de tiempo muestran tendencias crecientes en el transporte de sedimentos en el 68% de la cuenca del río Magdalena.
