Inundação em estuários : do histórico aos indicadores de avaliação do risco

As margens dos estuários são afetadas por episódios de inundação com origem em vários fatores forçadores. Ao mesmo tempo, são também zonas densamente ocupadas onde se registam danos relevantes. Neste contexto, torna-se importante o desenvolvimento de instrumentos de avaliação do risco de inundação que possam apoiar a gestão nestas áreas e que integrem simultaneamente as duas dimensões do risco (fatores forçador...

The complexity of the coastal zone: definition of typologies in Portugal as a c...

Mainland Portugal presents an extensive, diversified and complex coastal zone. This diversity gives rise to diverse geomorphologic features which support different densities of human occupancy and a range of land uses and activities. In this sense, the coastal zone becomes an area of great national strategic value, but has also into a multi-hazard zone. To understand this complexity, two statistical techniques,...

Improving Estuarine Flood Risk Knowledge through Documentary Data Using Multipl...

Estuarine margins are usually heavily occupied areas that are commonly affected by compound flooding triggers originating from different sources (e.g., coastal, fluvial, and pluvial). Therefore, estuarine flood management remains a challenge due to the need to combine the distinct dimensions of flood triggers and damages. Past flood data are critical for improve our understanding of flood risks in these areas, ...

Dealing with multisource information for estuarine flood risk appraisal in two ...

Estuaries are usually affected by compound flooding triggers that cause diverse territorial damages. While fluvial flood risk assessment frameworks are well established in the literature, integrated management instruments that deal with estuarine flood risk remain incomplete and often lacking. This research presents a methodology to extract relevant information from multiple sources post-event and a database bu...

Enhancing estuarine flood risk management: comparative analysis of three estuar...

Estuarine flood risk management is a challenge for coastal managers since this type of system is usually complex due to the presence of multiple trigger combinations that can induce flood events affecting different types of human occupation. Furthermore, legal directives demanded countries to have flood risk assessment tools therefore enhancing knowledge on estuarine triggers and flood damage typologies is usef...

Storm induced morphological changes in Carcavelos Beach, Portugal: contribution...

Field data based information on the coastal sediment dynamics becomes even more relevant for coastal managers in the present context of climate changes. Due to the sea level rise and the increase of frequency and intensity of coastal storms, coastal managers need to implement effective and efficient solutions for increasing coastal resilience, namely through reprofiling the beach for restoring the sediment bala...

Estuarine flooding in urban areas: enhancing vulnerability assessment

The assessment of vulnerability provides valuable knowledge in the risk assessment steps of a risk governance process. Given the multiscale, multilevel, and multisectorial aspects of flood risk, the diversified entities that directly and indirectly intervene in risk management require specific outputs from the assessment studies. Urban areas in estuarine margins are particularly exposed and vulnerable to floodi...

The contribution of historical information to flood risk management in the Tagu...

Estuarine areas are often affected by flood episodes with significant infrastructural and human damages caused by the overlap of different triggering factors. Currently flood risk management practices are subject to increased scrutiny by the public and relevant stakeholders requiring rigorous justification by flood risk managers and careful validation of the technical options and human and financial resources a...
