Coastal erosion forecasting is central to climate adaptation and risk management. However, shoreline dynamics exhibit complex spatio-temporal patterns with both local variations and long-range dependencies that conventional recurrent models struggle to capture efficiently. We propose a hybrid Mamba-LSTM framework for m...
