深水水道沉积动力学发展现状与展望
Advances of Depositional Dynamics in Submarine Channels
摘要
Abstract
[Objective]As the most extensive sediment transport systems on Earth,submarine channels shaped by turbidity currents transport billions of tonnes of sediment to the deep sea.[Methods]The internal structure,sedimen-tary architecture,and hydrodynamics of turbidity currents are revealed by summarizing the advances of depositional dynamics in a submarine channel.[Results and Conclusion](1)The definitions and flow properties(Re,Fr,and Ri number)of gravity current are provided.The general anatomy and structure of turbidity currents are shown by the head and body of the current,as well as the structure of velocity,density,and turbulence.(2)A review of the relat-ed literature describing sediment transport for uniform and non-uniform sediment beds and bedform development asso-ciated with open channel flow is provided.It is necessary to research the hydrodynamics of the turbidity current in submarine channel to reveal the morphology,geometry,overspilling,sediments distribution,and reservoir architec-ture,as well as guide deep-water hydrocarbon exploration.(3)Three main methods(field observations,experimen-tal modelling,and numerical modelling)for studying the depositional dynamics in submarine channels are intro-duced.(4)The frontier areas and controversial topics in current research on depositional dynamics in submarine channels are discussed.关键词
