Mechanistic Modeling of Self-Formed Channel Meanders on Submarine Fans (Collaborative Proposal)

9711912 Pirmez大型海底扇的曲流河道具有与陆上曲流相似的平面表达，但断面形状不同。海堤在海底河道中更为突出且不对称。Pis将描绘海底扇上河道化的泥沙驱动流与海底河道曲流演化之间的联系。他们还将开发海底曲流的数值模型，他们在水下曲流、河道和洪泛平原的丰富经验将非常有用。这项研究将有助于更好地了解近海主要河流系统的这些鲜为人知的形态特征。

9711912 Pirmez Meandering channels of large submarine fans have a planiform expression that is similar to subaerial meanders but cross- sectional shape differs. Levees are more prominent and asymetrical in the submarine channels. Pis will delineate the connection between channelized sediment-driven flows on the submarine fans and the evolution of submarine channel meandering. They will also develop a numerical model for the submarine meanders, where their vast experience in subaerial meanders, channels and floodplains will be very useful. The study will lead to a better understanding of these little known morphological features offshore major river systems.
