Short summary

This study introduces a computer model that simulates water flow both on the land surface and underground, and their interaction. The model can run efficiently on many kinds of computers, and its design lets each part update at its own pace to save time. In the tests performed, the model's results matched those from well-known tools in the field. Overall, the model offers a fast, flexible, and scalable way to study combined surface and groundwater behavior.
