FROM YELLOW RIVER MODELSTO MODELING OF RIVERS

The Yellow River in China is a heavily sediment-laden river that challenges the best minds to understand its hydraulic behavior. Scientific scale modeling of the river was first carried out in Germany, separately by Engels and Franzuis, in the early 1930s. It was the major river modeling at that time, and the disagreement between their results had profound effect on the regulations of the river and on later physical river hydraulic modeling. The background leading to the Yellow River models and the conditions of the experimental results are reviewed in this paper. Finally, issues related to numerical and physical modeling of rivers are discussed.
