| Abstract: | The existing study on the regularity of adjustment of channel cross-section in alluvial river is summarized,including such the realms as empirical expressions,extremal hypotheses and mechanical theory analysis,etc.The relations between the channel cross-section and runoff-sediment combination,bed boundary condition are analyzed.The adjustment conditions of channel cross-section in the lower course of Weihei River are analyzed briefly,and the relations between the river width and runoff-sediment combination and antecedent boundary are established.In the end,the characteristics of these three methods are summarized and some advices for the future study are proposed. |
| Keywords: | adjustment of cross-section empirical expression extremal hypotheses mechanical theory analysis lower course of Weihe River |
