Short summary
The spatial runoff is decomposed into a deterministic trend and deviations from it caused by stochastic fluctuations which are described by Budyko method and stochastic interpolation. This coupled method is applied to spatially interpolate runoff in the Huaihe River basin of China. Results show that the coupled method reduces the error in overestimating low runoff and underestimating high runoff suffered by the other two methods, so it improves the prediction accuracy of the mean annual runoff.
