FAQ
What are ungauged basins and why are they challenging?
Ungauged basins lack direct water flow measurements, making it difficult to predict streamflow and extreme events. This absence of observational data increases uncertainty and limits traditional forecasting methods.
Why compare Transformers to LSTMs for this task?
Transformers excel at capturing long-range dependencies in sequential data, while LSTMs are established for time-series prediction. Comparing them reveals which architecture better handles complex watershed dynamics with limited information.
