“…The hydroDL library contains models for several versions of LSTM models for hydrologic and water quality variables, multiscale models, physics-informed differentiable models (ecosystem, routing -so far small scale), and in the future Transformer models. Besides streamflow (Feng et al, 2020(Feng et al, , 2021, hydroDL has been employed to simulate soil moisture J. Liu, Hughes, et al, 2023), stream temperature , dissolved oxygen (Zhi et al, 2021(Zhi et al, , 2023, sediment (Chaemchuen et al, 2023), nitrate (Saha et al, 2023), phosphorous and snow water equivalent, etc.…”
