Standardization of sedimentary facies and topography based on the tidal channel type in Western coastal area, Korea

Abstract

ABSTRACT Eom, J., Choi, J.K.., Lee, Y.K., Ryu, J.H., Won, J.S., 2013. Standardization of sedimentary facies and topography based on the tidal channel type in Western coastal area, Korea The tidal flat area along the west coast of the Korean Peninsula is among the largest in the world. The Ganghwa-do tidal flat, which is an open type, the Geunso-bay tidal flat, which is a semi-closed bay, and the Hwang-do tidal flat in Cheonsu Bay have different benthic environments, formed by different surface sedimentary facies and topographic features. These benthic environments in each tidal flat are influenced mainly by the tidal channel network. In other words, knowledge of the tidal channel distribution pattern is a key for understanding the geophysical and surface-sedimentary facies. From a quantitative estimate of the tidal channel distribution pattern, it is possible to estimate the surface sedimentary facies and topographical features. In this study, we standardized the surface sedimentary facies and topography ...
