description A sediment transport study was carried out at the Urías Lagoon Entrance in Mazatlan, Sinaloa, Mexico. Tidal velocities and elevations were measured every two hours over two tidal cycles at the Lagoon Entrance. Simultaneously suspended sediment was sampled at the same location from two levels of the water column. Phase differences (2-3 h) were found between maximum tidal velocities and maximum suspended sediment concentration. The axial distribution of sediment concentration near the water surface (1 m) in the lagoon was also investigated. Increasing sediment concentration values were found from the entrance (3.2 mg l-1) to the head (19.9 mg l-1) of the coastal lagoon. In addition, the field- work included measurements of waves, bed-forms and bed grain size parameters. Bed load and suspended sediment transport rates were computed at the lagoon entrance for critical tidal velocities by using a program developed by Van Rijn (1990). The largest suspended sediment transport (0.261 kg s-1 m-1) and the largest bed load transport rate (0.009 kg s-1 m-1) were found for ebb tide at cycle 2. The results also included instantaneous vertical profiles of sediment concentration, current velocities and sediment transport at the selected point. Most of the vertical profiles indicate a sediment concentration increase with depth through the water column. The suspended sediment flux increases from the upper water layers to the last 0.30 m layer near the bed where the increase is faster.

Como parte de la investigación se midieron durante dos ciclos de marea elevaciones del nivel del mar así como velocidades de las corrientes en la entrada a la laguna y se realizaron muestreos de la columna de agua a dos niveles de profundidad para determinar concentraciones de sedimento 4n suspensión. Se encontraron diferencias de fase de 2-3 h ntre las velocidades máximas de las corrientes y las concentraciones desde la entrada (3.2 mg l-1) hasta la cabecera (19.9 mg l-1) de la laguna costera. En aadición, el trabajo de campo, incluyó mediciones del tamaño del sedimento y formas de fondo así como de las olas. Con los datos obtenidos se evaluaron tasas de transporte de sedimentos en suspensións y como carga de fondo para velocidades críticas de corrientes a través del modelo de transporte desarrollado por Van Rijn (1990). Las tasas mayores de transporte en suspensión (0.261 kg s-1 m-1) y tranporte como carga de fondo (0.009 kg s-1 m-1) se presentaron durante el ciclo de mareas 2 bajo condiciones de reflujo. Los resultados incluyen también perfiles verticales de concentraciones de sedimentos, velocidades de corrientes y transporte de sedimentos. La mayoría de los perfiles indican un incremento en las concentraciones de sedimento con el aumento de la profundidad a través de la columna de agua. El flujo de sedimento en suspensión se incrementa desde las capas superiores de agua hasta la capa de 0.30 m de espesor cerca del fondo, donde el incremento e más marcado. Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2012-07-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/32539Revista Internacional de Contaminación Ambiental; Vol. 16 Núm. 1 (2000); 27-36Revista Internacional de Contaminación Ambiental; Vol. 16 No. 1 (2000); 27-360188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/32539/29879Derechos de autor 2017 Revista Internacional de Contaminación Ambientalinfo:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/325392024-08-16T19:00:32Z
