13. A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais
The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed pa

14. Paradigms for the maritime works project in the context of climate change. / Paradigmas para os projetos de obras marítimas no contexto das mudanças climáticas.
Global warming and the consequent increase of the mean sea level rise will be a challenge to the maintenance and development of offshore structures in the coming decades. Both global climate change and the fact that the extreme storms are experiencing substantial changes have profound consequences for the society and the environment. The study aimed to prese

15. Caracterização ambiental de bancos areno-lamosos nos campos petrolíferos de Macau e Serra (RN), como subsídio às medidas mitigadoras ao processo erosivo
On Rio Grande do Norte northern coast the process of sediment transport are intensely controlled by wind and sea (waves and currents) action, causing erosion and shoreline morphological instability. Due to the importance of such coastal zone it was realized the multi-spectral mapping and physical-chemical characterization of mudflats and mangroves aiming to

16. Relações entre a morfodinâmica e a utilização em trechos da costa oceânica da Ilha de Santa Catarina, SC, Brasil
This Doctorate dissertation analyzes the relation among morphodynamic characteristics of oceanic sandy beaches and the use of its coast. The study area is the oceanic coast of Santa Catarina Island, in Florianópolis, SC, southern Brazil. First of all, data about forty beach profiles, which had been monitored, were collected. Several parameters were analyzed

17. Capacidade de Retenção de Fósforo e Material Particulado em Suspensão por Manguezal de Área Impactada por Efluentes da Carcinicultura. / Phosphorus retention capacity and Suspension of Particulate Matter in Mangrove Area impacted by effluents from Shrimp.
The mangrove forests stabilize the coastal erosion zone and act as a buffering between the continent and the sea. This forest presents high resilient degree, suggested to be used as marker of environmental changes. They play an important role in the energy flow and nutrients cycles. They are suffering with the growth of shrimp ponds. This tends to be respons

18. Estoque e qualidade da matéria orgânica do solo em áreas cultivadas com café sob sistemas agroflorestal e a pleno sol / Soil organic matter stock and quality in agroforestry and full sun coffee systems
Soil organic matter (SOM) restoring is considered a main goal in the enhancement of soil quality. The evaluation of changes in the SOM as a result of soil management practices is fundamental to identify strategies to increase agricultural production, avoiding soil degradation and decreasing the emission of greenhouse gases. In Brazil, no-tillage has been bro

19. Impactos sócio-ambientais do Processo de Erosão Costeira: subsídios ao planejamento e gestão na Praia da Caponga Cascavel CE. / Social and environmental impacts of coastal erosion process: planning and management grants Beach Caponga - Rattlesnake - CE.
A erosão costeira é um sério problema enfrentado pela praia da Caponga no município de Cascavel, litoral Leste do Estado do Ceará. O problema vem a pelo menos duas décadas causando danos econômicos significativos a região, tornandose emergencial. Além dos prejuízos visíveis configura-se como mais um empecilho ao desenvolvimento de atividades produ

22. Vulnerabilidade do litoral sul de pernambuco à erosÃo
This study proposes a methodology to estimate the vulnerability of coastal segments to erosion through a semi-quantitative approach and its application to 14 beaches on the southern coast of Pernambuco State, Northeast Brazil. Such analyses are important tools in the process of coastal management, aimed to establish priority areas for management. After resea

23. O litoral de JoÃo Pessoa (PB), frente ao problema da erosÃo costeira
The JoÃo Pessoa- PB coast like other places of the Brazilian Northeastern, show erosive problems associated to natural process and a urban disorder occupation, that happened from the 70 decade, of last century, when the city began expanding towards the beaches. This work was onjective to classify the study area in relation to coastal erosion vulnerability.

24. Morfologia e sedimentologia das praias do litoral sul do municÃpio de Olinda - PE
The littoral of Olinda has spaces with coastal erosion since the last century. Trying to soften the erosion and stabilize the shoreline, a good range of engineering techniques were used in the last 88 years. During the 60s decade were made two breakwaters semi submerged in front of the Carmo beach and 38 groins along the 1,8 km of the Bairro Novo beach. The
