Research Progress on Consolidated Silt in Estuarine and Coastal Areas

Authors:

Abstract

Consolidated silt is a special depositional landform. The properties, formation,y and evolution process of consolidated silt, which relates to the fields of marine sediment dynamics and marine geological engineering geology, is are of crucial importance for shore protection, navigation safety, and coastal engineeringmarine construction. In this paper,This paper introduces the concept, featurecharacteristics, and distribution of consolidated silt and focuses on mechanisms of formation and evolution is introduced. Regarding the formation and evolution mechanism as the main clue, rRecent research progress on consolidated silt is reviewed according to the three typical classic modes of formation and evolution mode (i.e. primary deposition mode, coarsening and sorting mode, and liquefaction and seepage mode). New research ideas and methods with regards to on consolidated silt is are prospected considered after analyzing the advantages and disadvantages of the emphasizing the existing three classic modes. It is proposed that future research directions should: combinening the basic approaches of marine soil mechanics and sediment dynamics; , carrying out the synchronized simultaneous observations of multiple -factors on characterizing the water, seabed surface, and internal seabed;, building an integrated conceptual model to describe the physical process; and establishing corresponding mathematical models to evaluate the formation and evolution of consolidated silt, are the future research directions.
