Tecnologias de jogos aplicadas à representação tridimensional de processos de erosão costeira em ilhas barreiras

Abstract

The weather and oceanographic driving forces shape the landscape of the Rio Grande do Norte coast from short to long term. In particular the northern side of this coast, an area of intense human and economic activities, installed oil industries, wind power generation, shrimp industries, salt industries and tourism. The present work, in general, demonstrates which elements were used to develop a simulation prototype for 3D and 4D viewing of predictions of erosion of this coast. For this development we used statistical methodologies (Linear and Harmonic Analysis), and technologies such as the development environment of Unity 3D games, besides the use of other elements and altimetric and bathymetric data. In the development of this simulation prototype, the proper characterization of the area was made from a historical series of data. We used meteo-oceanographic data, precision geodetic surveys, coastline assessment using USGS DSAS algorithms along with the use of the area's historic satellite images. The development of this product aims to help other integrated actions, better management and adaptation of the human activities inserted in this highly sensitive and changeable environmental mosaic of the northern coastal region of Rio Grande do Norte, allowing the sustainability of the social actors inserted in their multiples Uses. This processof the construction of simulation prototypes also aims to mitigate situations of extreme events. Since with the current scenario of climate change, it is increasingly necessary to use tools that allow the visualization and detection of flood and coastal erosion scenarios. With some modifications and reprogramming of erosion and flood algorithms, this methodological process can be used in continental environments. In this way, this simulation solution can be used in the most diverse environments that involve the theme of erosion and flooding, whether in coastal or continental environments.
