Rethinking runoff routing in differentiable hydrologic models

This code package provides the implementation used in our δHBV routing experiments, including the original δHBV model, the static response-operator routing model, and the dynamic LSTM-conditioned response-operator routing model. The package contains the training, testing, evaluation, and diagnostic scripts required to reproduce the temporal-split and PUB experiments reported in the paper. No CAMELS data, trained model checkpoints, or generated outputs are included; users should prepare the required data following the documented data interface before running the experiments.
