Abstract This study focuses on the causes, modalities and obstacles of sediment transfer in longest cell littoral sand drift documented Earth so far. Sand derived from Orange River is dragged by swell waves persistent southerly winds to accumulate four successive dunefields coastal Namibia Angola. All are terminated river valleys, where aeolian flushed back ocean; yet transport continues at sea, tracing an 1800 km long submarine highway. would extend northward beyond Congo if shelf did not...
The present work focuses on two recent flash floods in coastal Benguela (Angola), both triggered by moderate rainfall but which had disastrous consequences for local populations (namely 71 deaths 2015 and 17 2019). research involved a regional survey to establish the effects of these combined with geomorphological socio-economic analysis most affected areas understand main forcing factors. produced major damage restricted sectors within very small catchments (<16 km2). prevalence...
Sub-Saharan Africa has been the last continent to experience a significant number of cases in novel Coronavirus (COVID-19). Studies suggest that air pollution is related COVID-19 mortality; poor quality linked cardiovascular, cerebrovascular, and respiratory diseases, which are considered co-morbidities deaths. We examine potential connections between country-wide environmental conditions Senegal, Cabo Verde, Nigeria, Cote D'Ivorie, Angola. analyze PM2.5 concentrations, temperatures from...
O delta do Catumbela é uma importante acumulação sedimentar no litoral SW de Angola. Neste trabalho apresenta-se a estratigrafia da sub-aérea e análise dos processos responsáveis pela sua evolução morfo-sedimentar. baseou-se na sedimentológica materiais colhidos em sondagens com trado manual amostrador percussão. A geometria planta deste característica um dominado ondulação. comporta sedimentos praia, ocasionalmente níveis lagunares que são particularmente comuns próximo região Lobito,...
