Accelerated sedimentation in Caraguatatuba Bay, SP: material and man-induced effects

Morphological changes in a sector of the State of São Paulo coastline, known as "Enseada de Caraguatatuba", were recognized through interpretation of air photographs in 1:25.000, 1:20.000 and 1:8.000 scales and field surveys done during the period November of 1978 to August of 1981. Grain size, shape, roundness and cluster analyses of 53 samples from the associated sedimentary deposits allowed us to characterize their textural properties, as well as to understand the coastal processes involved in the evolution of the area during the last years.
