Abstract
The snowmelt runoff prediction using the fuzzy reasoning method has been developed. However, to improve the prediction accuracy, it is necessary to adjust the predicted hydrograph based on the level of prediction error.
In this paper, the fuzzy reasoning method with a function of predicted error correction is presented for the snowmelt runoff prediction. The applicability of the model is assessed and compared by making 3-hr lead time prediction of runoff in experimental basins. It is concluded forecast results by the use of proposed method have higher degree of accuracy in comparison with the snowmelt prediction model using only fuzzy reasoning method.
