Abstract
The water supply of Ranchi has been significantly affected by the declining capacity of a reservoir over time, primarily due to various infrastructural developments that have encroached upon its drainage area and reduced water inflow. This study aims to predict the reservoir water level (RWL) at Hatia Dam, a crucial water source for Ranchi, Jharkhand, India. For RWL prediction, machine learning (ML)-based models, including recurrent neural network (RNN) and long short-term memory (LSTM) models, were employed with lead times ranging from 10 to 90 days. The performance of these models was evaluated using several statistical metrics. The results indicate that the RNN model outperformed the LSTM model for a 10-day lead time, achieving a correlation coefficient (R) of 0.982, Nash–Sutcliffe efficiency (NSE) of 0.964, root mean square error (RMSE) of 0.414, and mean absolute error (MAE) of 0.227. Overall, both RNN and LSTM models demonstrated very good performance for lead times up to 60 days and satisfactory performance for a 90-day lead time. These findings provide valuable insights for strategic water resource planning and future RWL prediction.
