Abstract

Flocculation is an important process in fine cohesive sediment transport that still requires investigation as it is a complex process, involving the aggregation, break-up and reconformation of mineral and biological particles.
Fine cohesive sediments are found in rivers, estuaries and their adjacent areas. With the rapid economic development in the Changjiang (Yangtze River) estuary, human activities have intensified, including the development of shipping, and the exploitation of water and soil resources. The erosion and deposition problems in waterways and tidal flats have become increasingly prominent, affecting the evolution of geomorphology and ecological environment....
