1. Morphodynamics of a wave dominated embayed beach on an irregular rocky coastline
Resumo Praias dominadas por ondas ao longo de litorais rochosos recortados são consideradas de grande potencial turístico, devido a beleza de seus recursos naturais. A compreensão das interações entre os processos oceanográficos, geomorfológicos e a herança geológica dominante neste tipo de praias ainda requer maiores investigações que permitam qu

2. Behavior and identification of ephemeral sand dunes at the backshore zone using video images
ABSTRACT The backshore zone is transitional environment strongly affected by ocean, air and sand movements. On dissipative beaches, the formation of ephemeral dunes over the backshore zone plays significant contribution in the beach morphodynamics and sediment budget. The aim of this work is to describe a novel method to identify ephemeral dunes in the backs

3. Morfodinâmica associada entre duna, praia e zona submarina como subsídio a adequada ocupação do espaço costeiro na Praia do Peró - RJ. / Morphodynamics associated between dune, beach and underwater area as an aid to proper occupation of coastal space in Praia do Pero - RJ.
The coastline offers a veritable mosaic of diversity in coastal landforms, which enable the development of a number of different economic activities. Coastal environments are highly dynamic and involve a complex series of continental and oceanic processes. The beach of Pero, located between Cape Buzios and Cabo Frio, Rio coast, appears as an area distinct fr

4. Sedimentation processes and beach morphodynamics active at the Doce River mouth, Espírito Santo State, Brazil
A sedimentação costeira adjacente à desembocadura do Rio Doce, Espírito Santo, Brasil destaca o efeito de jato hidráulico desempenhado pela descarga fluvial. Por ocasião da enchente, os sedimentos marinhos transportados pela corrente longitudinal são represados a barlamar da desembocadura, causando progradação nas praias adjacentes e erosão nas pra

5. Análise de risco à erosão costeira na região de Tibau do Sul/RN através de mapeamento geoambiental e análise morfodinâmica
The research area is located on the county of Tibau do Sul, in the east coast of Rio Grande do Norte State, about 80km south of the capital Natal. The tourism represents the main income activity and Pipa beach is the most visited beach in the city, annually receives a large influx of domestic and foreign tourists. Some recent studies have reported the occurr

6. "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

7. 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

8. 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

9. 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

10. 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

11. 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
