In recent years,there has been a growing interest in using artificial intelligence(AI)for rainfall-runoff modelling,as it has shown promising adaptability in this *** current study involved the use of six distinct AI models to simulate monthly rainfall-runoff modelling in the Bardha watershed,*** models included the artificial neural network(ANN),k-nearest neighbour regression model(KNN),extreme gradient boosting(XGBoost)regression model,random forest regression model(RF),convolutional neural network(CNN),and CNN-RNN(convolutional recurrent neural network).The years 2003-2007 are classified as the calibration or training period,while the years 2008-2009 are classified as the validation or testing period for the span of time 2003 to *** available rainfall,maximum and minimum temperatures,and discharge data were collected and utilized in the *** compare the performance of the models,five criteria were employed:R^(2),NSE,MAE,RMSE,and *** CNN-RNN model simulates the rainfall-runoff model in the Bardha watershed best in both the training and testing periods(training:R^(2) is 0.99,NSE is 0.99,MAE is 1.76,RMSE is 3.11,and PBIAS is􀀀1.45;testing:R^(2) is 0.97,NSE is 0.97,MAE is 2.05,RMSE is 3.60,and PBIAS is􀀀3.94).These results demonstrate the superior performance of the CNN-RNN model in simulating monthly rainfall-runoff modelling when compared to the other models used in the *** findings suggest that the CNN-RNN model could be a valuable tool for various applications related to sustainable water resource management,flood control,and environmental planning.
