| description |
Monthly averaged suspended sediment load data from seven rivers in northern Colombia (Caribbean alluvial plain) draining into the Caribbean Sea were analyzed to quantify magnitudes, estimate long-term trends, and evaluate variability patterns of suspended sediment load. Collectively these rivers deliver an average of around 146.3 × 106 t yr−1 of suspended sediments to the Colombian Caribbean coast. The largest sediment supply is provided by the Magdalena River, with a mean suspended sediment load of 142.6 × 106 t yr−1, or 38% of the total fluvial discharge estimated for the whole Caribbean littoral zone. Between 2000 and 2010, the annual suspended sediment load of these rivers increased by as much as 36%. Wavelet spectral analyses identified periods of intense variability between 1987-1990 and 1994–2002, where major oscillation processes appeared simultaneously. The semi-annual, annual and quasi-decadal bands are the main factors controlling suspended sediment load variability in fluvial systems, whereas the quasi-biennial and interannual bands constitute second-order sources of variability. The climatic and oceanographic drivers of the oscillations identified through wavelet spectral analyses define a signal of medium-long-term variability for the suspended sediment load, while the physiographic and environmental characteristics of the basins determine their ability to magnify, attenuate or modify this signal |

En conjunto, estos ríos entregan un promedio de alrededor de 146.3 × 106 t año-1 de sedimentos suspendidos a la costa del Caribe colombiano. El mayor suministro de sedimentos lo proporciona el río Magdalena, con una carga de sedimento suspendida promedio de 142.6 × 106 t año-1, o el 38% de la descarga fluvial total estimada para toda la zona litoral del Caribe. Entre 2000 y 2010, la carga anual de sedimentos en suspensión de estos ríos aumentó hasta en un 36%. Los análisis espectrales de Wavelet identificaron periodos de variabilidad intensa entre 1987-1990 y 1994-2002, donde aparecieron simultáneamente los principales procesos de oscilación. Las bandas semestrales, anuales y cuasi-decenales son los principales factores que controlan la variabilidad de la carga de sedimentos suspendidos en los sistemas fluviales, mientras que las bandas cuasi bienales e interanuales constituyen fuentes de variabilidad de segundo orden. Los impulsores climáticos y oceanográficos de las oscilaciones identificadas a través del análisis espectral de wavelets definen una señal de variabilidad a mediano y largo plazo para la carga de sedimentos suspendidos, mientras que las características fisiográficas y ambientales de las cuencas determinan su capacidad para magnificar, atenuar o modificar esta señal.Restrepo, J.
