The migration of transgressive coastal dunes over urban and farming areas is commonly observed in the semi-arid northern coast of the Brazilian northeast. However, it is unusual in the humid tropical coast of southeastern Brazil. This paper aims to investigate the aeolian dynamics and the drivers of the burial process over the Itaúnas District, Espírito Santo State landscape, by transgressive coastal dunes. Methodological procedures consist of remote sensing techniques, geoprocessing, wind regime simulations, and mathematical calculations of migration rate parameters. Satellite images were georeferenced using ArcGIS 10.3 software and wind regime information was simulated using HYSPLIT software using wind reanalysis data. The results suggest a sediment transport rate of 44.98 kg/m/s, wind drift potential of 123.96 v.u. and dune migration rate estimated at 4.0 m/yr. It was found that the northern and western sectors of the studied dunefield have the highest migration rates towards the main access road, water resources and urban area. The values obtained are considered significant because it is a coastal segment subjected to a humid tropical climate.

在巴西东北部的半干旱北部海岸，通常可以观察到海侵沿海沙丘在城市和农业地区的迁移。然而，它在巴西东南部潮湿的热带海岸并不常见。本文旨在通过海侵的海岸沙丘研究圣埃斯皮里图州伊陶纳斯区景观的风沙动力学和埋葬过程的驱动因素。方法程序包括遥感技术、地理处理、风态模拟和迁移率参数的数学计算。使用 ArcGIS 10.3 软件对卫星图像进行地理配准，并使用 HYSPLIT 软件使用风再分析数据模拟风况信息。结果表明泥沙输送速率为 44.98 kg/m/s，风漂移潜力为 123.96 vu，沙丘迁移速率估计为 4.0 m/yr。研究发现，所研究沙丘的北部和西部地区向主要通道、水资源和城市地区的迁移率最高。获得的值被认为是重要的，因为它是受潮湿热带气候影响的沿海部分。
