Background: Rainfall_Runoff modeling is necessary for hydrologic and hydraulic engineering design, integrated management of water resources, and forecasting flood. Objectives: The Objectives of this research was to build amodelof the relation between the runoff and the climatic parameters (rainfall, evaporation, temperature, relative humidity) in Alkabeer Aljanobee river in Syria by using artificial neural networks (ANN). Methods: Two type of dynamic neural networkswere used, the first type is Focused Time _Delay Neural network (FTDNN), and the second type is NARX network (HYPERLINK "https://en.wikipedia.org/wiki/Nonlinear_autoregressive_exogenous_model" \\o "Nonlinear autoregressive exogenous model" nonlinear autoregressive exogenous model). Also, Twenty four models were tested, each model had different combinations of inputs with time steps delaystake place in space [0 -3] days, in addition to historical values of runoff with time steps delaystake place in space [-1 -3]days.Results:This study reached to that the model which has input layer consists of rainfall, temperature, evaporation, relative humidity at time t=0 through t=-3, in addition to previous runoff at time t=-1 through t=-3, gives the best performance of formed neural networks. The architecture (19-25-1) ( 19 neurons in input layer and 25 neurons in hidden layer and one neuron in output layer) gives the smallest value of mean squared error (MSE)6.23*10^6, while the correlation of coefficient (R)equals 97.42 % for using data set. Conclusions: Thus, this researchhasshown the capability of using ANN in forecasting runoff depending on climatic variables and their effect on the runoff, the results have also shown that using historical runoff data improve the performance of the network very well.
