Study of the surface water circulation in San Blas channel (Argentina) using landsat imagery

Abstract: A B S T R A C TThis paper deals with the application of satellite images to study turbidity and water circulation patterns in San Blas channel during a theoretical tidal cycle. Eight Landsat TM and ETM images acquired under clear-sky conditions and representing different tidal stages were selected from a pool of Landsat images provided by the argentinean National Commission of Space Activities (CONAE) and the US Geological Survey. Standard digital image processing techniques were used to perform geometric and … Show more

“…Rainfall is characterized by the large space-time variation, typically of semiarid regions. An important factor to take into account is the prevailing and strong winds from NE quadrant, averaging 35-38 km h −1 with frequent gusts up to 100 km h −1 (Beigt et al, 2011).…”

“…Se observa una deflexión de la totalidad de los bancos sumergidos del delta de reflujo en sentido horario. Según el análisis estadístico realizado sobre un año de datos en una estación meteorológica ubicada en la localidad de San Blas (Beigt et al, 2011), el viento más frecuente es de dirección norte y el más fuerte proviene del N-NE. Ambas direcciones producen olas que afectan las geoformas provocando la curvatura de bancos y canales hacia el sur.…”

“…Según la clasificación de Hayes (1979) este ambiente correspondería al límite del régimen micromareal-mesomareal. Los vientos fuertes que caracterizan el área de estudio, provenientes del NNE, modifican las alturas y horarios de las mareas (Beigt et al, 2011) y por otro lado generan formas costeras que permiten inferir la dirección de deriva litoral hacia el exterior del canal.…”
