In order to analyze the runoff situation of Xiaojinchuan river basin
Markov chain model is used to predict the annual runoff situation. Combined with the changes of historical inflow
by calculating the Markov transition probability of the mutual transformation of abundant
normal and dry in history
the runoff situation of Mupo hydropower station in the next year is predicted according to the inflow situation of that year. Taking the situation prediction of Mupo hydropower station in 2018 for example
the case analysis is carried out. The results show that the prediction results are consistent with the actual results
and the runoff situation prediction analysis method has strong practicability
which provides a practical idea and method for runoff situation prediction analysis.
