Application of dynamic Bayesian networks in hydrologic forecast
Zhang Li · Computer Engineering and Applications Journal · 2010
Bayesian network is one of the most efficient models in the uncertain knowledge and reasoning field.A rainfall-runoff prediction model based on dynamic Bayesian network is put forward in this paper.The network model is based on knowledge of the field experts and the causes of rainfall-runoff,they can produce the probability of the flow rate by calculating the conditional probability among variables on the basis of historical rainfall and runoff data.Finally through the simulation of historical data about Wei He river basin from Xianyang gauge station to Lintong gauge station,the model and the results are analyzed.
