Abstract Fluvial and surge-tide extremes can occur synchronously resulting in compound flooding estuaries, greatly intensifying the hazard. This flood risk has potential to increase future as frequency, phasing and/or intensity of these drivers change. Improved understanding how extreme fluvial discharge surge-tides interact will help inform mitigation methodology. In this paper, therefore, we ...

Exploratory statistical partitioning methods (K-means Clustering analysis) were applied to ADCP monitoring datasets collected inside the Douro and Minho estuaries. This analysis is aimed discriminate acoustic responses according variations of suspended particles within ensonified medium. Based on interpretation results, this work establishes general sediment transport patterns at both estuaries...

Estuarine fish assemblages are subject to a great environmental variability that largely depends on both upstream fluvial and downstream marine influences. From this ecohydrological view, our study introduces a macroecological approach aiming to identify the main environmental factors that structure fish assemblages among European tidal estuaries. The present paper focuses on the influence of l...

The nitrogen and carbon stable isotope ratios (dN and dC) of the pygmy mussel, Xenostrobus securis, were determined for three estuaries with varying levels of catchment disturbance in northern New South Wales, Australia. The lower Manning River catchment supported the highest human population densities and 3% residential development with some livestock agriculture (41%); the Wallamba River catc...

A coupled set of partial differential equations and associated boundary conditions is written to describe circulation salt-flux processes for estuaries in which turbulent mixing results primarily from tidal currents. Similarity solutions, motivated by characteristic salinity distributions observed estuaries, are obtained this compared with observational data. The separated into modes analogous ...

Estuaries host channel networks that can range from meandering single-thread channels to complex comprising looping, branching, and offshoot structures through which water, sediment, nutrients are transported in both the flood ebb directions. In this article, we use graph theory quantify structural dynamical connectivity of multidirectional estuarine using network analysis techniques rooted hav...
