Executive editor
Machine learning is used widely in hydrological research nowadays, but benchmarking them for various applications was lacking. This paper addresses the question which machine learning model to be used for which application and why.
Short summary
Using global and regional datasets, we compared attention-based models and Long Short-Term Memory (LSTM) models to predict hydrologic variables. Our results show LSTM models perform better in simpler tasks, whereas attention-based models perform better in complex scenarios, offering insights for improved water resource management.
