Long-term morphological modeling and implication for estuarine regulation of the Modaomen Estuary, Pearl River Delta, China

The morphological evolution of estuarine areas occurs at multiple time scales. The Modaomen Estuary (ME) in Pearl River Delta (PRD), China, is one of the main outlets of freshwater and sediment into the South China Sea. A long-term morphodynamic model based on TELEMAC numerical modeling system was applied to the ME to explore input reduction of the river boundary condition, discuss the effect of wave, and analyze the classification of the ME and its long-term morphodynamic equilibrium.
