Caracterização morfodinâmica das praias de Tambaú e Manaíra – João Pessoa.

As central beaches from João Pessoa city, Tambaú e Manaíra are suffering some serious environmental damages, because of the disordered occupation of this area. This present graduation thesis tries to understand the coastal dynamic and the erosion that happens between Tambaú and Manaíra beaches in João Pessoa City (from the state of Paraíba – PB), with the proposal to discover the anthropic actuation in the environment. Tambaú and Manaíra beaches are spaces multipurpose that happens to have serious social conflicts of use and occupation of that ground and space. It’s necessary, then, to have this research, once these beaches are changing through the years, and while there’s an anthropic actuation on these beaches, these changes are happening even more. So, we must know how, when and how intense were these changes, and for this purpose, it’s necessary to observe some strategic points which had huge anthropic changes and huge changes by the urban dynamic of the area. To get to know the characterization of the coastal dynamic of these beaches, it was made a systematic observation of four locals selected: 9.212.688mN, 9.214.200mN, 298.590mE and 298.035mE – two locals in Tambaú beach and two locals in Manaíra beach. This observation was made during a year, from august 2011 to august 2012, always following the spring tide of the new moon. Morphodynamic and sedimentological data were collected. These locals are places which have intense urban agitation, lots of touristic boats and fishing boats, and lots of restaurants and bars. During the present study, it was possible to observe a lot of new edifications being constructed, more specifically bars, around the beach. The building of the hotel Tambaú serves as agent of change in stream sediments. There’s also a sandy tip that divides Tambaú beach, where we can notice a significant differentiation on the sand deposition. That’s why in the south side of the hotel, there’s a beach with an ‘estirâncio’ (specific term in Portuguese for a geographic specification of an area) and an extensive area after the beach with a lot of beach vegetation. Meanwhile, in the North way, there’s not enough sedimentation, and that’s why this area stays with a prominent slope, with a sand area only 30 meters large. Therefore, while the south area of the Hotel Tambaú is having a stability and sedimentation process, the north area of the Hotel is having the opposite process, of instability and erosion.
