A spatio-temporal approach to predict river discharge at ungagged watershed

Due to the importance of watershed management and river discharge necessity for metropolitan and agricultural areas this study aimed to evaluate the capability of TOP-kriging to model an ungauged basin. Such modeling is capable to be applied in management projects where there are lack of data. Zanjanrou as a sub-basin of Sefid rud watershed was model under existing condition. Results approved capability of employed model in modeling of ungauged watershed. Furthermore, temporal estimation of sub-basin 10 was preformed via ANFIS. Defined input combination were analyzed and the combination which included seasonality of process by 12 month age features led to best outcome.
