Abstract

Abstract

A long-term morphdynamic model (PRD-LTMM) and a non-linear dynamics theory Lagrangian coherent structures were applied to study the formation and development of the deposition bodies and main channels in the Zhujiang River Delta. The results indicated that mainly due to the convoluted coastline and hundreds of rocky islands scattered in the paleo-estuarine bay, seven different dynamic zones were formed, and many different kinds of medium and small scale dynamic structures were generated, then caused a great deal of deposition bodies. Deposition bodies is the basic unit in the hierarchical deposition structure of the Zhujiang River Delta. The general evolution of the Zhujiang River Delta can be summarized as a number of relatively separate ‘filling up’ processes. With the continuous growth of the deposition bodies, the broad water body was funneled into the channel frame of the Zhujiang River Delta network, and a continuous delta plain was formed.
