Highlights:

A new stepwise spatial-temporal-multimember domain decomposition method improves high-performance parallel computing for grid-based hydrological modeling
Computational units are partitioned into parallel spatial layers and conflict-free temporal indices with independent multimember arrays for ensemble modeling
The high parallel efficiency is achieved in river basins with highly imbalanced workloads between channel and overland routing process
