description An analysis of fluvial dynamics of the Amazon River between Corea Island (Colombia) and Aramosa Island (Brazil), northwest and southeast of Leticia, respectively, was carried out for a period of 18.1 years. The analysis was made using remote sensing image processing techniques applied to images acquired at different times. LANDSAT images were compared using the Brazilian Software SPRING with the method of unsupervised classification ISOSEG, to distinguish between land and water categories. LANDSAT scenes acquired on August 4 1986, November 20 1999 and September 14 2004 were selected from a database of 44 LANDSAT images based on minimal daily water level variations, with the largest temporal variation. The multitemporal analysis revealed moderate changes in the Amazon River's morphology. Increase of lateral accretion of islands (19,19%) and recent deposition (35,80%), over the period of time analyzed (18,1 years), indicate its depositional tendency. The percent migration rate (8,61%, 0,48%/year) and the maximum migration rate (133,56 m/year) suggest the current pattern for this reach of the Amazon River is meandering. This type of analysis provides important basic information for subsequent detailed geomorphological and sedimentological studies, and is an excellent tool for understanding the dynamics of holocene Amazon fluvial systems.

Este análisis fue realizado con el uso de técnicas de procesamiento de imágenes de satélite en imágenes de diferentes fechas. Las imágenes LANDSAT fueron comparadas a través del software Brasileño SPRING, con el método de clasificación no supervisada ISOSEG, para distinguir entre las categorías de tierra y agua. Las imágenes fueron adquiridas el 04 de agosto de 1986, el 20 de noviembre de 1999 y el 14 de septiembre de 2004, y fueron seleccionadas de 44 imágenes LANDSAT, con base en mínimas variaciones diarias del nivel del río, con la mayor variación temporal. El análisis multitemporal reveló moderados cambios en la morfología del río: incremento en la acreción lateral de islas (19,19%) y deposición reciente (35,80%) para el período analizado, indicando una tendencia deposicional. El porcentaje de la tasa de migración (8,61%, 0,48%/año) y su valor máximo (133,56 m/año) sugieren que en la actualidad hay un patrón de formación de meandros en este trecho del río. Este tipo de análisis provee información básica para subsecuentes estudios geomorfológicos y sedimentológicos detallados y es una herramienta excelente para comprender la dinámica holocena de sistemas fluviales amazónicos.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombia - UPTChttps://revistas.uptc.edu.co/index.php/ingenieria_sogamoso/article/view/902/902Derechos de autor 2009 Ingeniería Investigación y Desarrollohttp://purl.org/coar/access_right/c_abf44http://purl.org/coar/access_right/c_abf2Ingeniería Investigación y Desarrollo; Vol. 9 No. 2: julio-diciembre de 2009; 13-17Ingeniería Investigación y Desarrollo; Vol. 9 Núm. 2: julio-diciembre de 2009; 13-172422-43241900-771Xamazon riverremote sensingmultitemporal analysismultitemporalrío amazonassensores remotosanálisisMultitemporal analysis of the amazon river between Corea Island (Colombia) and Aramosa Island (Brazil)Multitemporal analysis of the amazon river between Corea Island (Colombia) and Aramosa Island (Brazil)info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6543http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/version/c_970fb48d4fbd8a127http://purl.org/coar/version/c_970fb48d4fbd8a85González-Rozo, José MaxSoto-Castro, Carlomagno001/12176oai:repositorio.uptc.edu.co:001/121762025-07-18 11:25:29.422metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
