What if a river bottom is basically flat? Dr. Hongbo Ma of Rice University finds that extremely fine-grained river systems develop low dunes or so-called planar beds, which minimize form drag and allow for the water to carry exceptional bedload. Measurements in the Yellow River in China form prime evidence for this theory. More...
