| titleOfInvention | A method and system for dynamic analysis of river flow capacity |
| abstract | The invention provides a method for dynamic analysis of river channel flow capacity, comprising: collecting measured typical cross-section information, measured flow rate, and measured flow velocity data of a river channel; drawing a typical cross-sectional diagram of a river channel, and drawing a beach lip elevation H water level of a typical section below the beach lip ～Current cross-sectional area curve diagram; read S i and S flat beach from the graph, then the remaining flow area S remaining under the flat beach water level = S flat beach- S i , and obtain S remaining min ; select the measured flow rate of the river section According to the fitting relational formula, the corresponding flow velocity V i under the real-time measured water level H i and the beach lip elevation H the flat beach velocity V flat beach under the beach lip are obtained; based on the V flat beach Calculate the residual flow capacity of the river channel with V i ; calculate the channel flow capacity based on the residual flow capacity of the channel and the real-time measured flow. The present invention is an analysis method for estimating the flow capacity under the flat river channel according to the remaining flow area below the flat beach channel, and realizes dynamic analysis of the safe flow capacity of the river channel. |
