The article analyses and predicts the hydrodynamic feature of Tang Shan bay on the basis of Ecomsed model, thus the calculation accuracy is improved. And then it predicts erosion-deposition characteristics of the study sea area.The paper assesses the influence of the artificial island construction in aspects of hydrodynamic and erosion-deposition environment. Research shows that the sea area in the north of the artificial island is deposition area because of sand excavation and the water inside is slightly deposit.

The article analyses and predicts the hydrodynamic feature of Zhifu bay on the basis of Ecomsed model, thus the calculation accuracy is improved. And then it predicts erosion-deposition characteristics of the study sea area. The paper assesses the influence of the sea wall backout in aspects of hydrodynamic and erosion-deposition environment. Simulating results show that the velocity of flow will increase after the sea wall backout and the ability of water exchange will be improved gradually. Research shows that the deposition-dominating areas are located at the north and east of study area, while the southeast side area is dominated by erosion. The accretion tendency will weaken in south of study area together with the accretion thickness 1cm/a annually, while the accretion thickness is 5cm/a in southeast of study area.

Cretaceous Period

The development of the area, of the Thames Estuary is briefly traced since the late Cretaceous period, with its present outline being due to a combination of factors. The overall subsidence of the North Sea area, the ‘Alpine5 fold movements, and the transgression of the sea since the retreat of the Weichselian icesheets have all contributed. The positions of the shore-line during the critical phase, 9600 b.p. to 8000 b.p., of this last transgression of the sea are shown. Subsequent to this main transgressive phase, erosion of the shoreline has been rapid due to storm-waves and tidal current action. An estimation of the average rate of subsidence and/or sea-level rise is given based on the concept of sedimentary equilibrium in which a figure of 12.7 cm (5 in) per century is arrived at.

The Impact

The Southern Adriatic Sea is a dynamic region under the influence of diverse physical forces that modify sea water properties as well as plankton dynamics, abundance, and distribution in an intricate way. The most pronounced being: winter vertical convection, lateral exchanges between coastal and open sea waters, and the ingression of water masses of different properties into the Adriatic. We investigated the distribution and abundance of tintinnid species in this dynamic environment in pre- and post-winter conditions in 2015/2016. A strong ingression of the saline Levantine Intermediate Water, supported by the cyclonic mode of the North Ionian Gyre in 2015 and 2016, in December was associated with a high diversity of oceanic species. An unusual spatial distribution of neritic-estuarine species Codonellopsis schabi was observed in deeper layers along the analyzed transect, which emphasizes the strong influence of physical processes on deep water biology in the South Adriatic. A shift of population toward greater depths (mesopelagic) and modification of deep sea community structure was recorded in April as a consequence of the winter convection-driven sinking of tintinnids. Our findings indicate that tintinnid abundance and composition is heavily influenced by physical conditions and they are good indicators of the impact of physical forces, including climate changes, on marine environment.
