13. Analise morfodinamica do Rio Mogi Guaçu / Morphodynamics analysis of the Mogi Guaçu River
This study shows that fluvial dynamics of the Mogi Guaçu River (NE State of São Paulo, SE Brazilian) is influenced by hydrographic basin geological structures and lithologies that sustain the river bed. These structures and lithologies affect the shape of the longitudinal profile, changing the relationships between the stream flow dynamics and sedimentary

14. AvaliaÃÃo geoambiental das praias do municÃpio de JaboatÃo dos Guararapes, regiÃo metropolitana do Recife
As praias do MunicÃpio de JaboatÃo dos Guararapes vÃm passando por sÃrios riscos de erosÃo marinha, devido principalmente, Ã intensificaÃÃo descontrolada do uso e ocupaÃÃo destas Ãreas. Em funÃÃo disso, buscou-se fornecer uma avaliaÃÃo geoambiental das praias de Barra de Jangada, Candeias e Piedade (litoral sul da RegiÃo Metropolitana do Reci

18. Urban expansion and geomorfological expansion in backwater of reservatories: comparative analisis of two drainage basins that are in the source of Guarapiranga, São Paulo / Expansão urbana e evolução geomorfológica em remansos de reservatórios: análise comparativa de duas bacias hidrográficas em guarapiranga, São Paulo
The environmental problems created by the accelerated urban growth in the last fifty years have brought severe consequences to the group of people living in big urban centers. For this reason many scientists, mainly in the field of Earth sciences, have searched the development of new techniques, methodologies and parameters to measure, recognize and attenuat

19. "Morfologia e sedimentologia ao longo do sistema praia-duna frontal de Ilha Comprida, SP" / "Morphology and sedimentology along the beach-foredune system of Ilha Comprida, SP".
Ilha Comprida is a Holocene sandy barrier-island located on the south coast of São Paulo State, 63 km long and 2 to 5 km wide. Its transverse boundaries are Cananéia and Icapara inlets, at the SW and NE, respectively. The beach-foredune system of Ilha Comprida have experienced intense morphological variation in time, as showed by the successive truncations

20. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w

21. SANDY BEACH MORPHODYNAMICS AND MACROBENTHIC COMMUNITIES IN TEMPERATE, SUBTROPICAL AND TROPICAL REGIONS - A MACROECOLOGICAL APPROACH
A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and

22. Riscos e gestÃo ambiental no estuÃrio do Rio malcozinhado, Cascavel-CE
The Rio Malcozinhado lagoon-estuarine system is located in the Cascavel municipality, in the Cearà State Southeastern littoral 75km away from Fortaleza, Northeastern Brazil. Its 380 km2 hydrographic basin lies on basement rocks, Plio- Pleistocene Barreiras Formation sediments and Quaternary deposits. The urban expansion of the area in the last two decades w

23. CaracterizaÃÃo morfo-sedimentar e evoluÃÃo de curto e mÃdio prazo das praias do Pina, Boa Viagem e Piedade, Recife / JaboatÃo dos Guararapes
The high rate of human occupation in the coastal area of the metropolitan region of the city of Recife since 1960, gave rise to numerous conflicts in the use and soil management, mainly due to the lack of public policies to regulate this fragile environment. This work has the objective to reach a diagnostic view of the environmental conditions of the Pina, B

24. Cartografia temporal e análise geoambiental da dinâmica da foz do Rio Piranhas-Açu, regiao de Macau-RN, com base em imagens Landast 5-MT
This work embraces the application of Landsat 5-TM digital images, comprising August 2 1989 and September 22 1998, for temporal mapping and geoenvironmental analysis of the dynamic of Piranhas-Açu river mouth, situated in the Macau (RN) region. After treatment using several digital processing techniques (e.g. colour composition in RGB, ratio of bands, princ
