AbstractThe study will integrate a geomorphic model of tidal channels into a 3-D stratigraphic model and will use the Fly River Delta as the case study for building and testing the model, and then use the model to fill gaps in the current understanding of the Fly River source-to-sink dispersal system. The work will develop computational tools for modeling a tidal delta module for the INSTAAR SedFlux model as well as adapting existing modules for tidal river flow and 3D delta evolution. The study focuses on the critical 'missing link' in the Fly/PNG system, one of the two main field sites for MARGINS Source to sink, which is the delta region.

摘要本研究将潮汐通道的地貌模型整合到三维地层模型中，并以飞河三角洲为例进行模型的建立和验证，进而利用该模型填补目前对飞河源-汇扩散系统认识的空白。这项工作将开发计算工具，为INSTAAR SedFlux模型建模潮汐三角洲模块，并使现有模块适应潮汐河流流量和3D三角洲演变。该研究的重点是Fly/PNG系统中关键的“缺失环节”，这是margin Source下沉的两个主要现场之一，即三角洲地区。
