                            <p>It is veryimportant to make reliable runoff estimations and runoff modeling studies whenplanning and designing of water resources. In the study presented, anartificial neural network (ANN) model was established to estimate daily runoffof Yigitler Stream in Gediz basin. The ANN model was also compared with multi-linearregression model structures. Performances of each model were examined withobserved daily runoff values of Yigitler Stream. After analysis, it was noticedthat the artificial neural network algorithm is more successful than the regressionmodel&amp;nbsp;</p></trans-abstract>

Hazırlanan YSA modeli çokludoğrusal regresyon modeli ile karşılaştırılmış, model performansları, YiğitlerÇayına ait ölçülmüş günlük akım değerleri ile sınanmıştır.
