Morphodynamic equilibria in double–inlet systems: Their existence, multiplicity and stability

Tidal inlet systems, which consist of back–barrier basins connected to the open sea by one or multiple inlets, are found at many places along sandy coasts. They are valuable for ecology (breeding and feeding areas), economy (gas–mining and sand–mining) and recreation, and are important for coastal safety. But they are also sensitive to external...

A reduced complexity model of a gravel-sand river bifurcation: Equilibrium states and their stability

We derive an idealized model of a gravel-sand river bifurcation and analyze its stability properties. The model requires nodal point relations that describe the ratio of the supply of gravel and sand to the two downstream branches. The model predicts changes in bed elevation and bed surface gravel content in the two bifurcates under...

A process-based, idealized study of salt and sediment dynamics in well-mixed estuaries

Estuaries are important ecosystems accommodating a large variety of living species. Estuaries are also important to people by their demand of freshwater for drinking, irrigation, and industry. Due to natural changes and human activities, the estuarine water quality, influenced by both salinity and turbidity (the cloudiness or haziness of water),...
