The main goal of the project is to quantify the relationship between the depositional environment in the Pearl River Delta/Estuary and its sedimentary facies. The environment will be described by the driving forces (hydrodynamic system) for the sediment transport features and ecological as well as anthropogenic impacts. Special attention will be paid to the role of events (strong storms/typhoons) for the redistribution of sediments. Facies characteristics describing the sediments are grain size, physical, mineralogical and geochemical properties. The relation between facies and environment will be analysed using methods of multivariate statictics. In addition, a transfer function will be elaborated to describe the relation between hydrographic regime and redistribution of sediments. What-if-sceanarios shall express the reaction of the sedimentary system to a change in the depositional environment. Assumptions of the IPCC will form the base of scenarios of sedimentological response to climate change. The models will be designed and implemented in a GIS environment.

该项目的主要目的是量化珠江三角洲/河口的沉积环境与其沉积相之间的关系。环境将通过沉积物输运特征的驱动力（水动力系统）以及生态和人为影响来描述。将特别注意事件（强风暴/台风）对沉积物重新分布的作用。描述沉积物的相特征是粒度、物理、矿物学和地球化学性质。应用多元统计学方法分析了沉积相与环境的关系。此外，将阐述一个传递函数来描述水文情势和沉积物再分布之间的关系。假设情景应表达沉积体系对沉积环境变化的反应。气专委的假设将构成沉积学对气候变化的反应设想的基础。这些模型将在地理信息系统环境中设计和实施。
