Trend and Mutability Analysis for River Runoff Time Series
Abstract: The river runoff time series has certain characteristics of trend and mutability, and the potential mutation point can be analyzed by discussing the variation regulation of those features, thus further grasping the runoff evolution law of runoff series. Taolinkou reservoir was selected as an example, and its trend and mutability properties of inflow runoff were analyzed, which clarifies the evolution characteristics of relative runoff series. It is shown that all kinds of runoff time series present the decrease trend year by year but no mutation obviously. The results can provide technical support and theoretical basis of sub-sequent model selecting of runoff forecasting, reservoir dispatching and water resources allocation.
