The Brazilian coast has come to be valued and transformed into a landscape of consumption from the combination of socioeconomic factors occurred mainly after the war. The use and occupation of land held in an unplanned way become the main human influences responsible for the dismantling of the morphological structures important in the maintenance and protection of coastal environments. This dissertation aimed to analyze the transformations of the landscape through the use and occupation of land between the years 1965 to 2003, and to identify changes in the beach Caueira by monitoring the morphodynamic beach profile and the line coast carried out between January 2010 and January 2011. The methodological procedures used in the study told with literature relevant to the subject of cartographic documents and data collection in the field. From the knowledge of the geo-environmental conditions and mapping of the processes use and land cover of Holocene coastal plain of the city of Itaporanga D Ajuda four different times, it was found many changes resulting from the combination of natural phenomena and / or anthropogenic interference contributing to transformation and evolution of the landscape over five decades. Through the monitoring system praial in five sectors of the coast for a year, it was possible to identify the morphodynamic beach stage, the occurrence of periods of erosion and sediment deposition and morphological features of these successful processes. These indicators were associated with natural climatic conditions and the degree of anthropogenic interference. The crossing of this information points to know more susceptible to destruction unleashed by the combination of natural and anthopogenic factors.
