Abstract

Abstract

From the perspective of interdisciplinary study, a brief review is conducted on the concept of "equilibrium" essential for the disciplines that the estuarine and coastal studies are closely related to. Based on output of the morphodynamic model PRD-LTMM, the water depth and corresponding area are selected as the state variables to construct the probability spaces that are used to calculate information entropy of the sub-delta systems. By comparing evolution of the depositional dynamic structures, which are briefly sketched in the context,and the geomorphic information entropy, it is found that the information entropy can be used as a phenomenological state function of the "morphodynamc equilibrium" in a given sense.
