Method for predicting river channel erosion of yellow river
The invention relates to a method for predicting the dangerous situation during a flood season of a water conservancy project, in particular to a method for predicting whether erosion occurs to a river channel of the yellow river during the flood season or not so as to provide an early warning means for flood prevention and emergency rescue and belongs to the water conservancy field. The IPC international patent classification number of the method is E02B 1/00. The method for predicting river channel erosion of the yellow river includes the steps that when a mathematical model is established, parameters representing the physical characteristics of a deposition block are introduced, the starting critical flow velocity of a deposition block of the river channel is calculated in combination with test and measured data of a river reach to be predicated, the stress condition of the deposition block in the start process can be reflected more truly, whether the river reach is eroded or not every time a flood occurs can be accurately predicted, and corresponding emergency rescue preparation is made.
