| Abstract: | Annual runoff forecasting is of great significance for the rational development and utilization of water resources and regional planning of society and economy.The problem of annual runoff forecast considering the influence of the uncertainty of original data was studied by using the rough set theory in this paper.Combining with actual examples,the entire forecast process by using rough set theory,which included from the establishment of forecast model,selection of effective data,generation of decision-making rule,to the final forecast results,was presented.The examples analysis showed that it was feasible for using the rough set theory to forecast annual runoff considering the influence of the uncertainty of data. |
