The objective of this study is to understand the evolution of the typologies (physicochemical and phytoplankton) in Aglou-Sidi Ifni coastline according to hydrometeorological and climatic hazards. To achieve this objective, monitoring of the phytoplankton community and water physicochemical parameters was conducted at three stations along this coastline and during the winter and fall seasons of two different annual cycles (2014-2016). The first cycle experienced heavy flooding while the second cycle experienced severe drought. This study revealed spatial and temporal variability in phytoplankton composition and the relative abundance of its major groups. Temporal variability may be due to changes in the physicochemical characteristics of water masses as a function of continental inputs and wave intensity, which differ from cycle to cycle and season to another. Whereas the spatial variability would be due to the modification of these physicochemical characteristics from one station to another under the influence of the morphology of the coast in this zone, which curves westwards and carries Cape Aglou at its northern end, thus making the station of Sidi Ifni more exposed to currents than the other two stations which are somewhat sheltered.

Resumo: Este artigo analisa o comportamento do regime de chuvas, distribuído no município do Rio de Janeiro, a partir de dados observados em mais de 30 estações pluviométricas monitoradas pelo Sistema Alerta Rio da Prefeitura do Rio de Janeiro (SAR-RJ), entre os anos de 1997 e 2014. Na análise da variação temporal e espacial da precipitação no município é possível identificar possíveis tendências e padrões do volume precipitado em função da sazonalidade e localidade. O estudo se baseia na confecção de mapas de isoietas mensais, obtidos pelo programa Surfer 10, cuja representação gráfica das características pluviométricas de cada região é analisada mediante determinados fatores ambientais como relevo, clima e estações do ano. Os resultados evidenciam índices pluviométricos acentuados em todo o município e de forma concentrada no período entre outubro e abril. Conclui-se que regiões como Barra/Barrinha, Alto da Boa vista, Tijuca, Jardim Botânico, Rocinha e Vidigal apresentam precipitações mensais superiores aos demais locais, independente do período, devido a presença de áreas verdes preservadas e fatores climáticos variados. A padronização das chuvas na cidade do Rio de Janeiro está diretamente associada a fatores ambientais como uso e ocupação do solo, relevos de maciços geográficos e região oceânica.Abstract:This article analyzes the rainfall regime behavior, distributed in the city of Rio de Janeiro, based on observed data more than 30 rainfall stations followed by Sistema Alerta Rio da Prefeitura do Rio de Janeiro (SAR-RJ), from 1997 to 2014. When analyzing the spatial and temporal variability of rainfall in the city, it is possible identify some trends and patterns of the volume of rainfall according to the seasonality as well as the locality. This study consists to elaborate monthly isohyetal maps, provided by Surfer 10 software, whose graphical representation of each region is analyzed through certain environmental factors such as topography, weather and seasons of the year. The results show high rainfall rates on the city and concentrated between October and April. This article concludes that regions such as Barra/Barrinha, Alto da Boa Vista, Tijuca, Jardim Botânico, Rocinha and Vidigal present rainfall rates higher than other regions, regardless of the period of the year, due to existence of preserved green areas and different climatic factors. The rainfall pattern in the city of Rio de Janeiro is directly connected to environmental factors such as land use/cover, mountain massifs and coastal region.
