HYDRODYNAMIC MODELING IN THE MUNDAÚ-MANGUABA ESTUARINE-LAGOON COMPLEX (AL)
Hydrodynamic circulation. SisBaHiA®. Estuary.
The Mundaú-Manguaba Estuarine-Lagoon Complex (MMELC) is a system composed of two lagoons, Mundaú and Manguaba, which are connected through narrow channels that terminate in an ocean inlet that shifts positions dynamically. Despite the great socioeconomic significance for the state of Alagoas, the complex has an accelerated process of environmental degradation due to anthropic practices such as the launching of sanitary sewage, industrial effluents and exploitation of natural resources. In this perspective, hydrodynamic and water quality models are useful tools as support to strategic decisions regarding coastal planning and management. Thus, this work aims to analyze the hydrodynamic circulation of the MMELC, considering the morphological changes occurring at the mouth of the estuary and using the two-dimensional model of the Hydrodynamic Environmental System (SisBaHiA®). Therefore, the present study will promote simulations in two distinct periods (2006 and 2017), which were determined using images from the Landsat 5 TM and Landsat 8 OLI satellites. For the implementation of the computational model it is necessary to compose input data such as domain discretization, bathymetry, roughness, initial and boundary conditions, boundary definition and forcing (wind, flow and tide). The results will be analyzed from the elevations and velocities.
