The introduction of parallel processing as an alternative to super-computing provides opportunities for rapid numerical integration of equations describing open-channel hydrodynamics. Parallel routing models can enhance the capabilities of deterministic watershed response models while increasing computational speed, provided these models employ cellular processors and efficient processor-management techniques. One-dimensional, open-channel conceptual cellular analogues of discretized hydrodynamic systems are illustrated, adapting existing finite-difference approaches. Cell programming can be extended to include hydrology and operations of water-control structures. Hybrid computer systems may be economically tailored in the future to specific water management applications.
