Prediction of and measures against risks by an extreme flood in the lower Yellow River

摘要

An experiment on a bed-movable model has been done to predict what will take place when an extreme flood flows through the channel similar to the current one of the lower Yellow River downstream of Dongbatou. Special attention is paid to the consequences in terms of change in streaming patterns, overflowing area, shifting of the mainstream course, and the situations of the flow going along the bank. Corresponding measures have been proposed against the potential risks.
