Phân vùng địa mạo, động lực học hình thái ven bờ và khả năng xuất hiện bùn loãng tại luồng tàu biển Việt Nam

Abstract

Fluid mud occurs quite normally at several navigation channels with such specific natural characteristics: coastlines shapes, sedimetary shores, river, tides and marine dynamics factor, and mud specifications. This fenomenon is rarely recorded in other areas with different natural characteristics with those mentioned above. According to professional experience, there are several specific natural characteristics for fluid mud to be happened in navigation channels including: tides, delta estuary with high sediment volume and busy navigation.

On the basis of coastlines and estuary classification, as well as analysis on river marine dynamics in Vietnamese estuaries, monthly bathmetry survey data, this report provides general evaluation on the interrelationship between these factors and the possibility of fluid mud appearance in specific navigational channels. As a result, the effectiveness of navigation channel operation in Vietnam would be strengthened.

Keywords: Fluid, mud Navigational channels, sedimetary, coastlines classification.
