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.

小行星9711912 大型海底扇的曲流河道具有与陆上曲流相似的平面形态，但横截面形状不同。 在海底航道中，堤防较为突出，且呈不对称分布。 本研究将描述海底扇上的渠化沉积物驱动流与海底河道曲流演化之间的关系。 他们还将为海底曲流开发一个数值模型，他们在陆上曲流、渠道和洪泛平原方面的丰富经验将非常有用。 这项研究将导致更好地了解这些鲜为人知的形态特征离岸主要河流系统。
