Regression Method of Calculating River Real-time Discharge for Noncontact Current Gauging
CAIFu-Dong
Abstract：Noncontact river lfow measurement is easier to implement and has lower risk due to its less artiifcial participation. Despite of its advantages, however, only surface velocities instead of velocities of a cross section are directly measured, which means the real-time discharge of the cross section of the river cannot be calculated as in those traditional methods. This paper proposes a regression model for calculating river real-time discharge under noncontact measuring condition. The error performance analysis of the model is also presented. Based on the model, the real-time discharge of the river can be calculated with surface velocities, river depth and cross section data provided by noncontact measurement.
