Spatiotemporal extent of diel and episodic hypoxia in bottom water of a shallow, well-mixed estuary
Globally, declining dissolved oxygen levels represent a critical ecological challenge for coastal regions. This study investigates the spatiotemporal dynamics of hypoxia within the Banana River Lagoon, a shallow subtropical estuary, revealing its impact on fish populations and nutrient cycles. Utilizing a network of 80 monitoring stations, researchers documented significant diel and seasonal variations in bottom water oxygen concentrations, correlated with temperature, light, and sediment composition. Notably, areas near organic-rich sediments experienced more frequent daytime hypoxia.
Numerical simulation of sediment transport characteristics under tidal action in the Qiantang estuary
Understanding sediment dynamics in high-energy estuaries is critical for effective disaster prevention and resource management. This study introduces a validated, unstructured triangular-mesh numerical model specifically designed to simulate sediment transport within the Qiantang River Estuary (QRE), accounting for density variations and riverbed evolution. Empirical calibration and validation against field data demonstrate reliable representation of hydrodynamic and sedimentary conditions, revealing significant intra-tidal fluctuations and a distinct turbidity maximum zone.
