Abstract

Missing value in hydrological research is common, and there is a growing interest to recover missing streamflow data as accurate information is required for various purposes. Due to missing data limitations, this study aims to evaluate the performance of the RNN-based method compared to the non-RNN based imputation methods to predict recurrence in a streamflow dataset. In this study, daily streamflow datasets from Malaysia's Langat River Basins were used. Following that, the datasets were fed into the Multiple Linear Regression (MLR) model. The validation of the best estimation methods was performed based on the estimation error, using methods such as Nash-Sutcliffe Efficiency Coefficient (CE), Mean Absolute Percentage Error (MAPE), and Root Mean Squared Error (RMSE). The findings revealed that the RNN-based method coupled with MLR (BRNN-MLR) outperformed all the approaches examined for filling missing values in streamflow datasets, with the highest CE value and lowest MAPE and RMSE value regardless of any missing data conditions
