本文分析了全球30个分流河道网络,发现分流河道长度与滋养面积之间存在类似Hack定律的标度关系,并揭示了两种不同的局部造陆模式。
原文开头
Apparent Hack’s law in river deltas Tian Y. Dong1*, Lawrence Vulis2, Hongbo Ma3*, Alejandro Tejedor4,5,2, Timothy A. Goudge6 River deltas are densely populated, ecologically vital landscapes threatened by rising sea levels. Distributary channel networks disperse sediment to build deltaic land, yet the relationship between the network organization and land building remains elusive. Inspired by Hack’s law, which shows that watershed drainage area scales with channel length in tributary networks, we analyzed a global dataset of distributary networks and found a nearly identical scaling relationship between distributary channel length and nourishment area, the land-building counterpart to drainage area. …
