Turbidity maximum formation in a well-mixed macrotidal estuary: The role of tidal pumping

Yu, Q. (author), Wang, Y. (author), Gao, J. (author), Gao, S. (author), Flemming, B. (author)

Traditionally, vertical circulation (induced by gravity circulation and tidal straining), tidal pumping, and resuspension are suggested as the major processes for the formation and maintenance of the estuarine turbidity maximum (ETM). Due to strong mixing, tidal pumping is considered as the dominating process in macrotidal estuaries. To analyze...

Chen, Zhi Guo (author), Chen, R. Y. (author), Zhong, R. D. (author), Schneeloch, John (author), Zhang, C. (author), Huang, Y. (author), Qu, F. (author), Yu, R. (author), Li, Q. (author), Gu, G. D. (author), Wang, N. L. (author)

Three-dimensional topological insulators (3D TIs) represent states of quantum matters in which surface states are protected by timereversal symmetry and an inversion occurs between bulk conduction and valence bands. However, the bulk-band inversion, which is intimately tied to the topologically nontrivial nature of 3D Tis, has rarely been...

The relationship between inundation duration and Spartina alterniflora growth along the Jiangsu coast, China

Li, R. (author), Yu, Qian (author), Wang, Yunwei (author), Wang, Zhengbing (author), Gao, Shu (author), Flemming, Burg (author)

The above-ground biomass of Spartina alterniflora salt marsh meadows is influenced by numerous interacting factors, among them elevation, tidal range and inundation duration. Bio-geomorphological models make use of either linear or quadratic equations, but it is important to be aware that the variables are area specific and hence not generic. In...
