A historical sketch of the landscape of the red river delta

This article is an attempt to stand back and re-imagine the landscape of the Red River over the last two millennia. The only static components of the Red River valley and delta are its mountains and geological deposits, everything else has changed over time. By marrying historical records with recent scientific findings on the Red River, this article outlines aspects of these changes; including changes to the climate and landscape, the possibility of shifting river courses, the movement of historical trade routes, and the rise of Thang Long-Hanoi.
