             abstract = "Transport of sediments in an estuary depends on the discharge from 
                         the rivers that drain the estuary and on meteorological 
                         conditions, which define the local circulation. Suspended solids 
                         modify the spectral response of water, making their observation 
                         from images of orbital sensors possible. This study proposes to 
                         evaluate the temporal and spatial variation of the suspended 
                         sediments in Patos Lagoon estuary, using the OLI sensor, Landsat-8 
                         satellite. Atmospheric and radiometric correction was realized for 
                         eight images from June 2013 to February 2014. The band 4, 
                         correspondent to the red wavelength, was segmented in 15 intervals 
                         of reflectance. In the winter, when winds from the south and 
                         southwest with high-speed predominates, the reflectance is small, 
                         indicating the entrance of water from the ocean in the estuary. 
                         The largest reflectance in the period of spring and summer is 
                         related to the transport of suspended sediments towards the exit 
                         of the estuary due to the predominance of winds from the 
                         northeast. Is possible to visualize the contribution of discharges 
                         from S{\~a}o Gon{\c{c}}alos channel, which is highest from June 
                         to November and lowest from December to February. Local 
                         variations, such high rainfall and change in wind direction, can 
                         cause unexpected changes in flow sediments. The concentration of 
                         suspended solids in the Patos Lagoon estuary presents spatial and 
                         temporal variations and is related to discharges from the rivers, 
                         rainfall, speed wind direction and meteorological tide. Data in 
                         situ is needed for the quantification of sediment.",
