The understanding of the incipient motion of cohesive sediment is a great challenge in the research of sediment incipient motion. It is recognized that cohesive forces are critical in determining the characteristics of cohesive sediment incipient motion. Based on the analysis of current research, cohesive forces are summarized in two main categories ( containing six types) according to the formation mechanism, and the formation mechanism and influencing factors of the typical electric double layer force and EPS cohesive force are explored. The impact of cohesive forces on cohesive sediment incipient motion is examined in terms of two aspects, i. e. sediment stability and incipient motion modes. Based on the discussion above, it is concluded that current studies generally focus on one certain cohesive force and seldom take the interaction and comprehensive effect between cohesive forces into consideration, lacking systematicness. Moreover, most of the current research achievements based on measured data are empirical and short of quantitative relationship derived from mechanism level, suffering from a theoretical deficiency. It is suggested that the various cohesive forces should be considered comprehensively in line with the specific sedimentary environment. What′s more, the formation mechanism research of cohesive forces should be concerned fundamentally, and the quantification research of cohesive forces needs more attention. [ABSTRACT FROM AUTHOR]

The response of tidal flats to storm surges is an important scientific problem in the evolution of tidal flats under climate change. To investigate the evolution of silt-muddy tidal flats in response to storm surges along the Jiangsu coast, the measured surface elevation of tidal flats pre- and post-storms and associated hydrological data were analyzed. The evolution of intertidal flats induced by storm surges is characterized by erosion in the upper intertidal flats while accretion in the lower flats. This is distinct from the evolution of sandy coasts which show erosion in the upper zones and accretion in the lower zones led by offshore sediment transport. A two-dimensional numerical model (Delft3D) is established considering tidal currents and sediment transport to simulate the bed evolution under calm and storm conditions, respectively. The hydrodynamic mechanism is explained for the regional characteristics of tidal flats, which shows an episodic effect on morphology after storm waves. The flood-dominated tidal current plays a key role on the long-shore sediment transport. [ABSTRACT FROM AUTHOR]

To explore the evolution mechanism of tidal flats under the influence of multiple factors, a cross-shore profile numerical model is developed based on vegetation growth and tidal processes. For a bare flat driven by tides, a general convex cross-shore profile is obtained after medium-to long-term simulation. Sediment supply determines the width of mudflat. and a higher sediment supply leads to a wider and gentler mudflat. For marsh flats, different spatial distribution of biomass affects tidal hydrodynamics differently. At the upper intertidal flat, the flow reduction effect with parabolic distribution of biomass production is stronger than that with linear distribution , and it is converse at the lower intertidal flat. A scarp is simulated at the edge between the bare flat and marsh flat, and it moves seaward as the sediment deposition on intertidal flats. [ABSTRACT FROM AUTHOR]
