| description | The invention relates to the technical field of water conservancy engineering, in particular to a river pattern division method based on a longitudinal river regime adjustment transmission and blocking mechanism. A water level drop value DeltaH of an upstream channel and a downstream channel of the river section and an elevation drop value DeltaZ of an upstream channel bed and a downstream channelbed are calculated, when DELTA H is not greater than DELTA Z, the river regime adjustment of the downstream channel is not transmitted to the upstream channel, and the river section is longitudinallyblocked. When DELTA H is greater than DELTA Z, that is to say, the river regime adjustment of the downstream channel is transferred to the upstream channel, the river section in this study is a longitudinal non-barrier section. The river type dividing method of the invention accurately analyzes the transmission and blocking mechanism of the longitudinal river regime adjustment, can accurately divide the research river ran |
