9711431 Parker 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.

9711431 Parker 大型海底扇的曲流通道具有类似于水下曲流的平面表达，但横截面形状不同。 海底航道中的堤坝更加突出且不对称。 Pis 将描绘海底扇上的渠道化沉积物驱动流与海底河道蜿蜒演化之间的联系。 他们还将开发海底曲流的数值模型，他们在海底曲流、河道和洪泛区方面的丰富经验将非常有用。 这项研究将有助于更好地了解这些鲜为人知的近海主要河流系统的形态特征。
